摘要
An input control current command signal (52) is modified in accordance with a number of compensation factors stored in a memory and corresponding to each of a number of angular shaft positions to provide a control signal to cause an inverter (84) to drive each of the number of phases of a permanent magnet axial-field motor (88) to cause the motor to produce a ripple-free torque output. The compensation values stored in the memory are identified and determined in accordance with the source of the torque ripple such as vibration, load operation, noise and variations within the motor construction.
