。[Scope of Claim for Utility Model Registration] An automatic door drive device configured to open and close a door by a three-phase induction motor 1 to which three-phase AC is input via an inverter circuit 3, wherein when the motor 1 is started, the motor A first control means controls the inverter circuit 3 so that the frequency of the AC output to the motor 1 gradually increases from a low frequency and the voltage of the AC output to the motor 1 is limited to a certain value or less corresponding to the frequency. When the motor 1 is driven at a constant speed, the frequency of the AC output to the motor 1 is constant, and the voltage of the AC output to the motor 1 is reduced when the rotation speed of the motor 1 is high, and the rotation speed of the motor 1 is An automatic door driving device characterized in that a second control means is provided for controlling an inverter circuit 3 to increase the speed when the speed becomes slow.
