Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/042237
Kind Code:
A1
Abstract:
A motor control device: prepares compensation wave information beforehand in a storage unit; monitors a state quantity (torque reference, motor speed) that defines a drive state that creates pulsation in a motor's generated torque; selects, from the storage unit, compensation wave information that corresponds to the positive or negative polarity of the state quantity; generates a sinusoidal compensation wave for periodic torque pulsation (torque ripple, cogging torque), on the basis of the selected compensation wave information; and controls the drive of the motor on the basis of a compensated torque reference replacing a torque reference entered from a host device for the purpose of controlling the drive of the motor, said compensated torque reference being a combination of the torque reference and the generated compensation wave.
