Device for controlling the torque of an asynchronous electric motor by controlling the phase of the motor stator voltage |
摘要 |
A device controls the torque of an asynchronous electric motor by controlling the phase of the motor stator voltage relative to a motor flux on the basis of a set point for the quadrature component of the stator current in a frame of reference related to the flux in turn derived from the motor torque set point. The device includes a first difference detector for detecting any difference between the set point and the current value of the quadrature component and a first regulator operating on the basis of the difference to provide the phase value to be applied to the motor to reduce the difference.
