Several advantages of permanent magnet synchronous motor

Update:18 Feb 2021

Permanent magnet synchronous motor has the advantages of simple structure, small volume, light weight, low loss, high efficiency and high power factor. It is mainly used in high-performance servo drive system which requires fast response, wide speed range and accurate positioning, and the replacement of DC motor. Permanent magnet synchronous motor can be installed on the axle as a whole to form a whole direct drive system, that is, an axle is a driving unit, which saves a gearbox. The application of permanent magnet synchronous motor is so extensive, let's take an inventory of the advantages of permanent magnet synchronous motor.
1.The permanent magnet synchronous motor (PMSM) has no gearbox, so the bogie system can be designed at will, such as flexible bogie and single axle bogie, which greatly improves the dynamic performance of the train;
2. PMSM has high power efficiency and power factor;
3. The permanent magnet synchronous motor allows a large overload current, and its reliability is significantly improved;
4. The whole drive system of permanent magnet synchronous motor is light in weight, the weight under spring is lighter than that of traditional axle drive, and the power per unit weight is larger;
5.The permanent magnet synchronous motor system adopts a fully enclosed structure, no transmission gear wear, no transmission gear noise, no lubricating oil, no maintenance;
6. The permanent magnet synchronous motor has small heating, so the motor cooling system has simple structure, small volume and low noise. the above are the major product advantages of permanent magnet synchronous motor, hoping to help you better understand permanent magnet synchronous motor.
