Title:
ELECTRIC MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/116787
Kind Code:
A1
Abstract:
Disclosed is an electric motor control device with a simple structure which can satisfactorily suppress torque ripples in response to the rotational state of an electric motor. The device is provided with a sign determination unit (1), which determines the sign of torque output by the electric motor; an adjustment parameter setting unit (2), which sets the phase difference of the benchmark phase of a sinusoidal ripple correction wave (NTR6) for lowering electric motor torque ripples, where said phase is set in response to the sign of the output torque as a correction parameter; and a correction wave generation unit (3), which generates the ripple correction wave (NTR6) based on the correction parameter.
