Lithium electric stirring

High speed motor, also known as spindle motor, can be broadly referred to as electric spindle, high-speed electric spindle, etc. It usually refers to a motor with a speed exceeding 10000r/min, and currently the highest speed can reach 300000r/min.

High speed motors are further divided into: AC asynchronous motors, DC synchronous permanent magnet motors, BLDC brushless motors, BLDC variable frequency motors, etc.

Advantages of high-speed motors:

Due to its high speed, the motor has a high power density and a much smaller volume than ordinary motors of the same power, which can effectively save materials;

2. It can be connected to the prime mover, eliminating the traditional reduction mechanism, resulting in high transmission efficiency and low noise;

3. The high-speed motor has a small moment of inertia, so its dynamic response is fast.
