Understanding permanent magnet motors

Controlling the speed of ac motors is accomplished using a variable frequency drive (VFD) in most cases.

How does the permanent magnet motor work?

It does not need to know the position information of the rotor, and an open-loop control scheme with a constant voltage-frequency ratio is often used. The self-controlled permanent magnet synchronous motor also adjusts the rotor speed by changing the frequency of the external power supply.

What factors need to be considered when choosing a permanent magnet motor?

Permanent magnet motors are a type of electric motor that uses rare earth magnets to create the rotating magnetic field needed to turn the rotor.

How to distinguish the cooling method of the motor?

As a new type of high-efficiency energy-saving product, the permanent magnet synchronous motor has been widely recognized and developed rapidly.

What are the benefits of a permanent magnet motor with a frequency converter?

The frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply.

Permanent magnet synchronous motor, which equipment to match is more reasonable to save energy?

the permanent magnet synchronous motor is more suitable for loads with frequent load changes

Energy-saving comparison calculation of high-efficiency permanent magnet motor and asynchronous motor
