Title:
MOTOR CONTROLLER
Document Type and Number:
Japanese Patent JP2007043889
Kind Code:
A
Abstract:

To provide a motor controller capable of reducing noise and vibration generated by a rotation order component of a motor.

A sine wave torque output part 8 receives a detection signal from a rotation speed detection means 4, extracts the amplitude Kn and the phase θn from a map Mn corresponding to a rotation order n, and outputs to a control arithmetic section 6 a control signal for generating a sine wave torque T represented by formula 1: T=Kn×sin{n×θd-θn}(wherein the θd represents a rotation angle). The control arithmetic section 6 generates a q-axis current command value iq for causing a drive torque following the pulsation of a load torque and a sine wave current command value is for causing a sine wave torque, and outputs a synthetic value (iq+is) to a drive circuit section 7.
