What is the difference between permanent magnet synchronous motor and asynchronous motor for new energy vehicles

2021-09-15

Compared with the asynchronous motor, the permanent magnet synchronous motor mainly differs in that the rotor is a permanent magnet, which reduces the loss caused by the excitation, and the stator is installed with windings to generate torque through alternating current, so the cooling is relatively easy.

What parameters of permanent magnet materials affect the performance of permanent magnet motors?

The development of permanent magnet motors is closely related to the development of permanent magnet materials. The world's first motor that appeared in the 1820s was a permanent magnet motor, which could generate an excitation magnetic field from a permanent magnet. But the permanent magnet material used at that time was natural magnetite (Fe3O4), which has a very low magnetic energy density, and the motors made of natural magnetite (Fe3O4) were bulky and were soon replaced by electric excitation motors.

Motor manufacturers take you to understand how much energy saving permanent magnet motors are compared to ordinary motors

How much energy saving is the permanent magnet motor compared to the ordinary motor? The details are as follows: the permanent magnet motor saves 10-50% of the energy than the ordinary motor. The specific equipment working conditions are different, and its power saving rate is also different. Energy efficiency, energy efficiency is above 95%; ordinary motors are three-level energy efficiency, energy efficiency is only about 90%.

FOC/DTC of permanent magnet synchronous motor, can you figure it out?

Permanent magnet synchronous motors are more and more widely used in automobiles, and their traces can be seen in actuators from power drives to steering brakes. Today I want to talk about the control of permanent magnet synchronous motor.
