PMSM electrical spindle has the advantage of high torque at both high and low rpms.
The rotor of the permanent magnet synchronous electric spindle has no induced current, and the rotor has low heat generation. It also has excellent hard torque characteristics, and still has high speed stability under load fluctuations, which can maintain the uniform rotation of the grinding wheel. Therefore, the surface quality of the processed parts is higher.
Therefore, it is widely used in CNC milling machines, CNC machining centers, robot arms and etc. It can be configured with BT40, BBT40, HSK63 and ISO40 noses.
