Here is the comparison of the advantages and disadvantages of synchronous motors and asynchronous motors by Motor Suppliers:


Let's talk about the Synchronous Motor first. Its advantages are obvious. Under the same weight and volume, the permanent magnet synchronous motor can output higher power and torque. Similarly, under the same power and torque, its weight and volume are small, leaving enough space and quality for another extremely important component, the power battery. In addition, the permanent magnet synchronous motor also has the characteristics of low noise.

As for the shortcomings, permanent magnets rely on rare earths. If you want high power, you need large permanent magnets, which are expensive; and although it is called "permanent magnet", it is easy to demagnetize in harsh environments such as high temperatures.


As for the Asynchronous Motor, the cost is very low, the process is simple, the operation is reliable, and the maintenance is convenient. It can work in a complex working environment and has a relatively strong ability to adapt to large changes in the surrounding operating temperature.


But under the same power and torque, the volume and weight required by asynchronous motors are much larger than permanent magnet synchronous motors.


You can choose a suitable motor according to your needs. The company also provides AC motors and induction motors. Please feel free to contact if necessary.
