Claims

[Scope of utility model registration request]

In a drive device for an electric actuator that is reversibly driven in an opening direction and a closing direction by a reversible drive motor, open-side and close-side field windings are provided between the open-side and close-side field windings of the reversible drive motor and a power source, respectively. A limit switch and a malfunction prevention relay at the fully closed and fully open positions are inserted in series, and an open position indicator and a closed position indicator are interposed between the normally open contacts of the open and closed limit switches and the ground. An electric actuator drive device characterized by being inserted into the drive device.
