MOTOR DRIVE DEVICE

A motor drive device is provided which is able to reduce loss between a drive power source and a controller. The motor drive device (6) includes a plurality of motors (4), a single drive power source (7) which drives these motors (4), and a controller (8) which controls energizing times during which motor coils of the plurality of motors (4) are energized, by a PWM drive method. The controller (8) includes phase shift portion (10a) which sets a PWM signal for causing a current to flow to the motor (4), into a phase different per motor. By the phase shift portion (10a) setting the PWM signal for causing a current to flow to the motor (4) into a phase different per motor, so-called overlap of energizing times of currents is avoided.
