To provide a device for suppressing and control vibrations of an electric motor, capable of suppressing the vibrations of the electric motor by a simple controlling method and moreover capable of achieving the suppression and control of the vibrations of the motor that can be applied to different car models, too, comparatively in a simple way.
An electric motor (SR motor) 3, as a traveling and driving power source of an electric vehicle, is controlled by a microcomputer. The microcomputer computes target torque in accordance with the opening of an accelerator. Based on this target torque (taking motor revolutions Nm and a battery voltage into consideration), command values (a current indicated value I, an angle-indicated value θ) obtained by referring to a map MP are commanded to control the torque of the SR motor 3. signal data of the motor revolutions Nm, detected from the SR motor 3, is passed through a band-pass filter 51. PD computation processing is carried out for the signal data of 0.1 to 50 Hz, derived by passing through the band-pass filter 51 to control the subtraction of the calculated corrected value from the target torque.
