Abstract
A motor drive device includes an inverter to apply power to a motor, and a plurality of relays to switch a connection state of the motor by each switching its state between a first state and a second state. A timing at which at least one of the plurality of relays switches from the first state to the second state is different from a timing at which the other relays switch from the first state to the second state.
