  Square wave control principle of brushless motor

  1.Theoretical basis of square wave control Square wave control is also called six-step control. In an electrical cycle, the motor has only six states, or the stator current has six states (three-phase bridge arm has six switching states). Each current state can be regarded as a vector torque in ...

  What are the daily maintenance tasks of servo motor?

  Users of servo motors often do not pay attention to the oil seal of the motor to ensure the improvement of the running speed of the motor. The servo motor can be used in places that will be invaded by water and oil drops, but it is not completely waterproof or oil-proof, so the servo motor shoul ...
