It includes a brake switch (22) that connects and opens a direct current power (20) with a brake coil (24L), an exciting circuit (50) generating a torque by connecting the direct current power (20) to a three-phase winding of a motor (11) and making the current flow into the motor (11), and a rescue switch (32) that connects and opens the exciting circuit (50) with the direct current power (20). The exciting circuit (50) includes a first excitation pattern in which one electrode of the direct current power (20) is connected to one phase of the three-phase winding, and the other electrode of the direct current power (20) is connected to the other two phases of the three-phase winding, a second excitation pattern in which the phase formed by the three-phase winding of the motor (11) is set forward by an electrical angle of 90 degrees in a direction in which a car (17) is to be moved, and an off pattern in which windings of two phases are set apart from the direct current power (20).
