| Abstract: | In accordance with structure of PM AC servo motor powered by current inverter,with expanding series,it analyses magnetic field harmonic wave produced by stator winding and rotor magnetizor of PM AC servo motor.And then,according to basic principle of that function each other between stator magnetic potential and rotor magnetic potential could produce torque,it derives formula of electro-magnetic torque. It poduced by harmonic wave of stator,rotor magretic potential can reduce torque waviness of servo motor,raise its performance and operation precision. |
