A motor drive device (20) includes a circuit (31) (e.g., an inverter) with a connection configuration that is switchable among: (a) a drive operative connection configuration that allows a motor unit (6) to be driven with power supplied from a battery unit; (b) a regenerative braking connection configuration; and (c) a short-circuit connection configuration that causes motor coils of the motor unit (6) to short-circuit to create a braking force. The motor drive device (20) also includes a short-circuit current controller (26) configured to control a short-circuit current that flows when the connection configuration of the circuit is (c) the short-circuit connection configuration. The motor drive device (20) also includes a regenerative braking and short-circuit braking switching controller (25) that may cause switching from (b) the regenerative braking connection configuration to (c) the short-circuit connection configuration, or vise versa.
