Abstract
A motor drive device which drives a motor including a winding set and a winding set that are electrically separate from each other includes an inverter that outputs three-phase alternating currents to winding set, an inverter that outputs three-phase alternating currents to winding set, and controllers that output drive commands to inverter and inverter by generating PWM pulses. Controllers generate the PWM pulses such that the three-phase alternating currents that are output from inverter to winding set and the three-phase alternating currents that are output from inverter to winding set have reverse polarities in three respective phases.
