Working principle of explosion-proof permanent magnet motor

Last time we introduced the magnetization requirements and design methods of permanent magnet motors. It can be seen that permanent magnet motors have attracted much attention from all walks of life. So for explosion-proof permanent magnet motors, what kind of product is it? Next, let's learn the working principle of explosion-proof permanent magnet motor.

Nowadays, with the rapid development of the motor industry, a new motor has been developed based on the previous explosion-proof motors, which is the explosion-proof permanent magnet motor. This new type of explosion-proof motor will also become the mainstream market in today's society.

Explosion-proof permanent magnet motors are widely used and have many functions. They are used in various mechanical fields such as petroleum, chemical industry, elevators, electric vehicles, fans, machine tools, etc., and its working principle and performance are also very suitable for these occasions.

The working principle of explosion-proof permanent magnet motor is as follows:

1. This kind of explosion-proof motor is a device that uses a magnetic field as a medium to convert corresponding mechanical energy and electrical energy into each other.

2. Create a magnetic field in the explosion-proof motor that can carry out energy conversion between motors and a corresponding gap. There are two methods. One is to generate a magnetic field through current in the windings of the explosion-proof motor. This is what is commonly used today. The basic principles of DC motor, synchronous motor and asynchronous motor used in time. The second type uses a permanent magnet material to generate a magnetic field, that is, a permanent magnet synchronous explosion-proof motor.

3. The permanent magnet synchronous explosion-proof motor is the same as the general electric magnetic synchronous explosion-proof motor. The only difference is that the traditional electric magnetic synchronous explosion-proof motor brings the magnetic field inside the explosion-proof motor through the current in the electric magnetic winding. Today's permanent magnet explosion-proof motors use a material with a permanent magnet inside the motor to generate a corresponding magnetic field. Therefore, there are corresponding differences between general explosion-proof motors and permanent magnet explosion-proof motors.
