Electrical circuit of a chandelier with a two-speed fan. Connection diagrams for a chandelier with a fan

During the hot season, a large ceiling fan performs better than other fan models in normalizing the microclimate in the room. The air flow from it covers a significant area. And even at low speeds, the effect is very pleasant for residents. The fact that the fan occupies a central place on the ceiling, which is usually used for a chandelier, does not cause problems, since in some models the functions of the fan and chandelier are combined.

But attaching an ordinary chandelier to the ceiling and combined model somewhat different. For an ordinary chandelier, a hook is sufficient, which is provided in any room. It is motionless and other than gravity, no other forces act on it. And when the impeller rotates, a torque arises. It is directed in the direction opposite to rotation. And this feature should be taken into account when hanging a ceiling fan of any design, especially when combined with a chandelier. In the absence of rigid fastening, axial movements will appear when the impeller rotates.

For high ceilings

Simple ceiling fan during these movements it is not noticeable. But the movement of light bulbs in a chandelier with a fan will create an unpleasant lighting effect in the room. Light and especially shadows will begin to move. If the ceilings in the room are high, suspended ceilings are usually installed. The base of an ordinary chandelier is made according to the level suspended ceiling and suspended on a chain or cable. These extension cords cannot be used for a chandelier with a fan. In this case, the best extension cord would be a metal pipe. Its diameter should be such that it fits onto the ceiling hook with two holes made near its end. These hook holes should be diametrically opposed.

The pipe is also convenient for placing wires inside it. Although the wires are connected as if to one device, they actually create two separately operating circuits. After all, during the day when the impeller rotates, lamp light is not needed. Therefore, to control the lamps in the simplest circuit, you will need the same thing as for a chandelier. And the fan has its own separate circuit. It allows you to adjust the speed of the impeller. The connection diagram of the simplest model is shown in the image below. It has one lamp and one impeller rotation speed. Therefore, to control such a chandelier-fan, a switch with two keys is enough.

Variety of models

The number of lamps can be three, five, and sometimes more. The impeller speed can be divided into two or three stages and can even be adjusted smoothly. You can also smoothly regulate the light of lamps using dimmers. There are many models of such combined structures produced and it is unlikely that they can be standardized with just a few schemes. In order not to experience problems with installing the connection diagram for such a chandelier, when purchasing, you need to make sure that the accompanying documentation is available and everything is clearly stated in it regarding connecting the product to the electrical network.

If the connection diagram for a chandelier with a fan turns out to be too complicated to assemble it with your own hands, there will probably be specialists who will do everything necessary. When the selected model contains sensors for lighting control, or impeller rotation speed, there is a separate control unit, the possibility of programming is better to resolve the issue immediately upon purchase by calling a specialist to connect such a chandelier with a fan. You can not only fail to assemble a complex circuit with your own hands, but also damage something.

A control circuit for the chandelier with a fan is included with the product and should be included in the packaging. In the latest modifications of electrical products, the manufacturer does not provide an operation diagram, but shows a connection diagram. This way he protects his products from counterfeiting.
The simplest schematic diagram of a chandelier with a fan and its connection to the electrical network is shown in Figure 1.

The principle of operation is that when you turn on the power using a single-key switch, the electric light and fan are turned on simultaneously, i.e. The light is on and the fan is spinning.
A slightly complicated circuit diagram for connecting a chandelier is shown in Figure 2.

Here the operating principle is separate, i.e. When you press one key of the switch, the light comes on, when you turn on the other, the fan runs. The fan operates regardless of the state of the lamp.
Turning on a chandelier with a fan in electrical network comes down to the correct connection of wires and this is a necessary condition for her work. Depending on the type of grounding, it comes different quantity wires to the apartment and, accordingly, to the devices. For apartments of old construction, the TN-C grounding system is used, which is shown in Figure 3 (click to enlarge).

The main thing in this system is that two wires come into the apartment - phase and neutral (PE and N conductors are combined). To connect a chandelier with a fan, you need to connect conductors N and PE on the terminal block of the distribution box according to Figure 4 (click to enlarge).

In this system, three wires come into the apartment - phase, neutral and ground. The PE conductor allows you to ground all equipment in the apartment and equalize the potentials. This system, is modern and well protects people and electrical appliances in the house from the effects of electricity. Used to connect modern devices.

It is not possible to consider each of the chandelier circuits with a fan due to the huge number of manufacturers who expand the capabilities of the product. Chandeliers with a fan are found on sale and each of them has individual possibilities, control and connection diagrams:

1. Chandelier with direct connection (Fig. 1);
2. With separate switching on of the chandelier and separate switching on of the fan (Fig. 2);
3. Fans with different blade rotation speed modes, with the ability to select a mode on a chandelier or multi-key switch.
4. Using optical sensors to turn on the fan and electric light, depending on the illumination of the room;
5. With a remote control unit, programmable settings: fan rotation speed, lamp brightness, depending on the light level, with the ability to set the on and off time for both lamps and the fan.
Chandeliers with big amount lamps, with upper and lower light, have the same principle of operation.
To properly turn on a chandelier with a fan, you must carefully read the connection diagram and follow the operating instructions or instructions for use.

A fan is a device that creates air flow for cooling or circulation to eliminate unpleasant odors or removal of harmful substances. Fans in everyday life are used as:

• tabletop or floor devices to create comfortable conditions in hot weather;
• exhaust devices in kitchens, bathrooms and toilets;
• V computer technology for cooling power units: power supply, processor, hard drives, as well as for housing ventilation;
• V welding inverters for cooling power electronic components.

Fans fail, but not in all cases you need to rush to a specialized workshop. The cost of repairing some products is sometimes comparable to the cost of purchasing new ones. Therefore, it is more advisable to try to repair them yourself.

DIY fan repair

Symptoms of a problem mechanical The fan parts are:

• strangers noises at work;
• speed reduction rotation, while the rotation of the shaft of the switched off device by hand occurs with force;
• full stop, in which rotation of the fan shaft by hand is impossible or requires significant effort.

TO electric malfunctions include:

• tripping of protective devices(circuit breakers) when the fan is turned on;
• smells burnt or overheated insulation during operation;
• speed reduction rotation when the shaft of the device is turned off;
• interruptions in operation when changing modes.

Mechanical faults that are not corrected in a timely manner progress and lead to electrical problems. Prolonged operation of the fan with jamming on the shaft leads to overheating and failure of the electric motor windings. A loose bearing allows the motor shaft to move in the radial direction, which leads to damage to the stator windings.

Therefore, if signs of a malfunction are detected, you must immediately begin to eliminate it.

Troubleshooting mechanical problems

Household fans do not have rolling bearings or the like, which are replaced in case of failure. They install plain bearings, the shaft rotates in bronze bushings. They are permanently pressed into the body. But even if you take them out of there, there will be nothing to replace them with. Therefore, it is necessary to lubricate such bearings in a timely manner. If they run dry for a while, the gap between the shaft and the bearing will increase. This will lead to axial runout of the shaft, resulting in extraneous noise, a decrease in speed and an increase in the rate of bearing wear. This is especially fatal for computer coolers.

Used for lubrication machine oil, but it is better to use spindle. If there is sewing machine, then the oil to lubricate it is the best option for fan bearings. For lubrication, the fan must be disassembled to get to the bearings. At coolers and some exhaust fans It is enough to peel off the protective film on one side.

Please note availability pollution bearing. In some cases, you will have to disassemble the assembly, clean it, and then reassemble and lubricate it. There is no need to apply a lot of lubricant: one or two drops are enough for the bearing to function normally. The rest will be splashed all over the body during the first launch. Drops of oil inside the case collect dust quite well.

If after lubrication there is still noise during operation or shaft beating, then the product will have to be thrown away. It is not possible to replace the plain bearing.

Troubleshooting the electrical part of the fan

When the fan stops completely, you need to check the serviceability power cord and switches operating mode. For this you will need a multimeter. Best method checking the power cord - measure the voltage at the input terminal block of the fan or at the points where the cord is connected to its internal elements. Be careful when testing: do not touch live areas with your hands. After checking, immediately remove the plug from the outlet.

The serviceability of the switches is checked by measuring their resistance in the “on” position. They can fail if used frequently. It is best to immediately measure the voltage on the electric motor, but for this you need to know electrical diagram fan And also the principle of its operation and control of the rotation speed.

The speed is adjusted by switching leads from the motor. In this case, one of its windings has a number of taps (tap taps), by switching which the number of turns on the stator changes. With this design, you need to measure before and after the switch to find out if it is working. If there is voltage and the motor does not rotate, you need to measure the resistance of its windings. If the device shows a break, it means that the engine is to blame for the malfunction.

Another element whose malfunction causes the fan to stop is phase shifting capacitor. In circuits where it is used, the electric motor has two windings. One of them is connected to the power supply directly, and the other is connected through a capacitor, which shifts the voltage across it in phase by 90 degrees.

If the capacitor malfunctions, the winding either does not receive power or there is no phase shift. In both cases, the electric motor will not rotate. You can check the serviceability of the capacitor with a multimeter in resistance measurement mode. In this case, you need to select the largest measurement limit. Before connecting the device, the capacitor must be discharged by shorting its terminals together.

If, at the moment the multimeter probes touch the multimeter, readings appear briefly, and then it shows a “break,” then the capacitor is working. If its readings are zero or infinity and do not change, then the capacitor is faulty and requires replacement.

The operating voltage of the new capacitor should not be less than that of the one being replaced, and the capacitance should correspond to the original one. Its value is calculated in relation to the parameters of the electric motor winding; if it is changed, the phase shift angle will be greater or less than 90˚, and the fan will not start or will rotate more slowly.

Attention, do not mix up the winding terminals. Before disconnecting, mark the wires and sketch how they were connected. Additionally, take a photo of the assembly before disassembling.

If breaks in the motor windings are detected, the repair ends. You can try to find the break point or make sure that the winding has burned out (this is indicated by the darkening of the color of the insulation of its wires). But rewinding modern household devices is not economically feasible, and to carry it out at home you need to have professional wrapping skills. Therefore, devices with burnt-out electric motors can be thrown away without remorse.

Air circulation is very important, so the combination of a ceiling chandelier with a fan creates optimal conditions for work. Such lighting devices can provide an influx of fresh air in any season. Reviews of these models indicate that the rotation of its elements does not lower the temperature in the room.

There are different prices for lighting fixtures with a fan:

• in a low price category that can be bought inexpensively;
• at an average price, based on the family budget, select the appropriate quality;
• There are luxury models, their price is quite high.

If someone wondered how to connect a chandelier with a fan independently in a three-phase network, then here you can find information on this issue.

Before you start connecting a chandelier with a fan, it is important to decide on its location so that the light falls evenly without disturbing the overall mood of the room. If you plan to connect it in place of the previous chandelier, then you can skip this point.

Next, define approximate weight chandelier and if you find that it weighs more than 13-15 kg, you need to install a beam that will help hold the chandelier. If you skip this step, you may damage the wires or the surface of the ceiling. In ordinary apartments it is unlikely that such a heavy chandelier will be found, so, most likely, you can do without installing an auxiliary beam.

Installation of distribution box

Before you start connecting the chandelier to the fan, you need to connect junction box with power cable. This must be done carefully and carefully, following all safety regulations.

The heart of the structure, that is, the electrical circuit, must be connected at a distance of slightly more than 10 cm with the installed box; a supply of wires after connecting the cable is necessary in case of damage to the wires. Then you need to cover all the wires with a special cover. All wires must be insulated and the box must be tightly bolted.

There are already many reviews that are full of pleasant words in favor of such a design. This is not surprising, because buying such a lamp means giving yourself a soft, pleasant coolness along with gentle lighting. Air conditioners consume a large number of electricity, which cannot be said about ceiling chandeliers-fans, which can be bought in a specialized store. For example, you can find a high-quality, sophisticated and functional model at Leroy Merlin.

Moscow stores have established themselves as reliable suppliers of high-quality designs, where you can easily find a wide variety of lighting fixtures and inexpensively. A photo of a chandelier with a fan will help you get to know the design better. In addition, the photos that are in this article can be an excellent assistant in choosing a chandelier suitable for combating stuffy and stagnant air in the room. The price of a chandelier with a fan is low compared to an air conditioner, and it is still more profitable to purchase such a design than an air conditioner and a chandelier separately.

I got a substandard West SF-1602T fan (with a mechanical timer) made in China, sold by our company Ost-West, almost for free. The approximate cost of a similar one is about $20. The motor windings did not ring. For external wires only gray-blue 0.1k. The external capacitor has one end to the black common and the other to just one terminal from the windings (after opening, see below). Nothing more useful. I removed the rear engine casing (the rotating mechanism and external capacitor are still attached to it) and middle part(plates with coils). The front casing with the rotor remained on the front panel of the fan as there was no need for manipulation.
A detailed inspection of the conductor contacts revealed several breaks (as if rotted) of the coil leads under the cambrics. Restored contacts. Added definition: black (general)-red 1.0k. Naturally nothing works.
As a result, an almost vandal attempt was made, but the only one, so the correct option (already doubtful) was to unsolder all the terminals of the coils. I didn’t think about resoldering the remaining contacts just in case, because it was already too late. I drew the conclusions with an accuracy of 99%. Three conductors came out from almost the same point - I didn’t sign them (well, it was inconvenient), I just sketched the location. After releasing the winding terminals from captivity, everything began to ring. Four windings - 1.0k, 0.2k, 0.1k and 0.7k. Using my sketches and logical calculations (about three conductors from one point), I reconstructed the connection diagram for the windings and capacitor (see figure)

Sketch of winding terminals:

Just in case, for possible connection experiments, all eight terminals of the windings using twisted pair cables (conveniently by color) were brought out of the motor casing. On the windings, I insulated all the wires with heat shrink and secured them around the circumference with a thick thread (as it was).
Reassembled in reverse order). Everything worked.
But the engine gets very hot!!! After five to ten minutes it’s already hot. It’s bearable to wrap your hand around, but the iron plates are hotter, and you can’t hold your finger on them for long. Where's the joint?
I checked the rotor grout. I pulled the iron together normally. It couldn't have worked out better. The free movement seems to be good. This takes into account the fact that the design is without bearings, on ordinary bushings. I repeat, the circuit was almost certainly restored to the original one. If necessary, I will give my sketch of the winding terminals (for electricians who have been smoking the topic)). The photo will not be available due to the lack of the necessary device. Maybe the Chinese robot got it wrong? Maybe I need to connect it differently? Extending the ends of the windings 20 cm beyond the motor should not seem to affect heating. I checked the resistance on the fork of a similar but working fan (with a timer) - approximately the same (1.3k-1speed, 1.2k-2speed and 1k-3speed). On simple fans, the resistance is two times less. It seems that the starting winding with a capacitor can be used as a working winding if the device power is no more than 1.5 kW. If the windings are connected to each other in some other way, then this will no longer be an original circuit. But maybe it will be better? Or maybe this is how it should be heated (not sure)?
I ask the guru for help!
