The household ceiling fan motor belongs to a single-phase motor, and the industrial ceiling fan motor part is a three-phase motor. The electric fan is a single-phase AC motor, which uses the capacitance to shift the phase to obtain a rotating magnetic field, which rotates the motor and drives the fan blades to rotate to produce wind.
Inductor speed regulation, i.e., different inductances of core inductors connected in series in the motor circuit. It is a series inductor [the governor is a multi-tap sense] to change the current through the motor.
When the current becomes smaller, the generated magnetic field weakens, and the force on the rotor wire is smaller, and the rotor rotates slowly. This includes external inductors and different taps that utilize the main coil of the motor.
The principle is: because the frequency of the power supply is fixed (50Hz), and the more pairs of stator poles of the motor when the motor is working, the slower the speed, so by changing the number of pole pairs of the stator when the motor is working, the speed of the rotor can be changed.
Single-phase asynchronous motor positive and negative**
Let the current flowing through the main winding be IA and the current flowing through the secondary winding be IB. In general, the number of turns of the working winding is large, the inductance is large, and it is an inductive load, so the IA lags the power supply voltage in phase.

Summary. The motors of plastic ceiling fans are often referred to as "AC motors" or simply "fan motors". It is a rotating electric motor that converts electrical energy into mechanical energy to drive the blades of the ceiling fan to rotate and generate air flow, thereby achieving the effect of cooling.
Compared with other types of motors, AC motors have the advantages of low noise and high efficiency, so they are widely used in home and commercial ceiling fans.

The fan motor is a single-phase motor, and there are two sets of winding coils in the single-phase motor, one is the running winding, and the other group is the secondary winding coil, that is, the starting coil, and the starting coil is matched with the starting capacitor to complete the starting of the motor and the motor steering work. The circuit diagram is as follows:
Because the direction of rotation of the ceiling fan is not used to switch back and forth, there is no need to turn the transfer switch.
If the speed of the ceiling fan is relatively high, a 1 3 microfara capacitor can be connected in series in the circuit to reduce the speed, and a switch can be connected in parallel at both ends of the capacitor as a high-grade transfer switch. This sail capacitor can be connected in series at either end of the live and neutral wires.

1. Wall control mode.
This control method is to install a switch on the wall to use, and it should be noted that if there is a lamp and a ceiling fan, these two are to be controlled separately, and to install this kind of wall control, you need 2 live wires, one is to control the speed and switch of the ceiling fan, and the other is to control the light.
2. Pull the rope.
This kind of ceiling fan is basically a combination of lamp and fan, and there will be two pull ropes in the middle of the ceiling fan, which control the lamp and fan separately and do not affect each other.
3. Remote control mode.
This kind of ceiling fan is much more convenient than the previous one, and it is more controlled by remote control like an air conditioner, and some remote controls also have a timing function. Generally, a receiver is installed inside the ceiling fan, which only needs a power cord and no other extra lines.
How to install a ceiling fan.
1. Height. The installation height of the ceiling fan must be calculated, if the ground is too close to easily hurt people, the installation height of the fan blade is generally on the ground, and the distance from the ceiling is 400 500mm.
2. Hook. This is the core of the fixed ceiling fan, when installing, you must confirm whether it is fixed, if the hook falls off and hits someone, it is not good, so the diameter of the hook should be larger than the hanging of the ceiling fan, which is safer.
3. Ceiling fan assembly.
The fan blades of the ceiling fan are designed according to the standard, and do not change its angle without permission, so as not to appear that there should be no obvious flutter when the fan takes the mu leaves in operation.
4. Hook installation.
The hook is generally installed when pouring concrete, and is generally installed on the beam or the floor of the ceiling, and this hook is very firm, and the hook basically adopts the steel bar with a diameter of 8 10mm.

The power of the ceiling fan is generally about 65 watts, and the power consumption is one degree for about 15 hours of continuous work.
The electric fan is about 60-100 watts of power, so it generally consumes about 100 watts of electricity after turning it on for an hour. 24 hours to figure it out for yourself. Generally, the larger the fan blades, the greater the electric power and the more power it consumes.
The power consumption of the electric fan is directly proportional to the speed of the fan blades, and the power consumption of the fastest and slowest gears of the same electric fan is about 40, and the power consumption of 1 hour in fast gear can be used in slow gear for nearly 2 hours. Therefore, if the fan meets the usage requirements, try to use the medium or slow gear.
The power consumption of electric fans is different depending on the power and speed of the wind. If the power of the electric fan is 40 watts per hour, it needs to consume kilowatt-hours of electricity per day; If the power of the electric fan is 100 watts per hour, it needs to consume kilowatt-hours of electricity per day; If the power of the electric fan is 150 watts per hour, it needs to consume kilowatt-hours of electricity per day. The power consumption of electric fans is different depending on the power and speed of the wind.
If the power of the electric fan is 40 watts per hour, it needs to consume kilowatt-hours of electricity per day; If the power of the electric fan is 100 watts per hour, it needs to consume kilowatt-hours of electricity per day; If the power of the electric fan is 150 watts per hour, it needs to consume kilowatt-hours of electricity per day.

The first floor describes the phenomenon more or less correctly, but the understanding of the essence of the problem is not deep and clear. The working principle of the motor is to use the magnetic effect of the electric current, and at the same time as the magnetic effect, the coil generates an induced electromotive force opposite to the applied voltage, which causes a fundamental change in the structure of the circuit, so that the circuit cannot be understood from the perspective of Ohm's law, so the phenomenon you mentioned appears.
Diagram of the working principle of the stepper motor.
There are three pairs of magnetic poles A, B and C on the stator of the motor, and there are coils around the magnetic poles, which are called phase A, phase B and phase C respectively, and the rotor is an iron core with teeth, and this kind of stepper motor is called a three-phase stepper motor. If the first circle is passed by direct current, a magnetic field will be generated, when the coils of the three poles of A, B and C are electrified in turn, then the three pairs of magnetic poles of A, B and C will take turns to generate a magnetic field to attract the rotor to rotate. First of all, there is a phase coil (set to phase A) to be energized, then the two teeth of the rotor are attracted by the magnetic pole A, and the rotor stays at the position of Figure 5-5a. >>>More
