Motivation is a machine that converts electrical energy into mechanical energy. The wall fan motor structure mainly includes two parts: the rotor and the stator. The rotor is the rotating part of the wall fan motor and consists of a shaft seat. Its basic principle is to use the interaction between a charged conductor and a magnetic field to convert electrical energy into mechanical energy. The arrangement of conductor windings determines the type and characteristics of the wall fan motor.

Classification of AC motors

According to function, AC motors are usually divided into AC generators, AC motors and, synchronous cameras according to their functions. Due to the reversibility of the motor's working state, the same motor can be used as both a generator and a motor.

The division of wall fan motors into generators and motors is not very precise, but some motors are mainly used as generators, and some motors are mainly used as motors.

According to the variety, AC motors are divided into two categories: synchronous motors and asynchronous wall fan motors. The speed ns of the rotor of the synchronous motor is the same as the speed of the rotating magnetic field, which is called the synchronous speed. There is a strict relationship between ns and the frequency (f) of the connected alternating current and the number of pole pairs (P) of the wall fan motors.


The role of the motor

A wall fan motor is a single-phase AC motor that uses capacitors to shift phases to obtain a rotating magnetic field, which rotates the motor and drives the blades to rotate to generate wind.

Adjust the working voltage of the wall fan motor to adjust the speed. The methods used are: use reactance of different inductance in series without changing the working voltage of the wall fan motor, or use the change of the conduction angle of the triac to adjust the working voltage of the wall fan motor.

Changes in wind direction: One is to use the rotating blades in front of the blades to change the direction of the wind, the other is to use the worm mechanism to decelerate and drive the connecting rod to drive the fan to rotate.


How to test a wall fan motor?

1. Human eyes can’t see the problem. It’s best to use the digital universal meter to test and adjust the gear to 0Q-2kQ. The wall fan motor is a single-phase AC 220v. It starts with a starting capacitor. The wall fan motor has two windings. One is the starting winding and the other is the running winding.

2. The resistance of the starting winding is larger and the resistance of the running winding is smaller. There are actually 3 wires out of the wall fan motor. Use a multimeter to measure the DC resistance between the 3 wires. The maximum value is the resistance of the starting winding + the running winding, and then the starting winding. The resistance value, and finally the resistance value of the running winding. 3. Put the multimeter in the 20MQ gear, measure the windings, and choose any of the three wires of the wall fan motor at will, so that the insulation resistance between it and the stator core of the wall fan motor should be above 2M. You can use this to check whether the wall fan motor is has a problem.


It is the responsibility of each manufacturer to produce an industrial wall fan motor that meets the standards, so as to ensure the safety of the use of wall fan motor and the healthy development of the wall fan motor market. Guangzhou Yuexun Electric Appliance Co., Ltd. many tests on the wall fan motor before they leave the factory, and the quality qualification rate is guaranteed. If you are in the wall fan motor business, you can consider our cost-effective products.
