It incorporates a set of electromagnetic contactors that are made inoperable, and connects the operating contacts provided in the contacts to the line connecting the three-phase AC power supply and the terminals of the motor for driving the electric valve. A limit switch is provided so that the electric valve can rotate freely, and a limit switch is provided that disconnects each self-holding circuit of the excitation coil for opening and closing the electric valve from the power supply when the electric valve is in the fully open position and the fully closed position. In an electric valve drive device that performs An electric valve drive device characterized in that contacts are interposed in lines connecting a power source and the excitation coil on the side of the excitation coil for opening or closing that is not excited by the swinging of the contact.
