。[Claims for Utility Model Registration] 1. An electric motor provided with an electric motor M that rotates a valve body 1 that opens and closes a flow path as it rotates, and a control means 100 that controls the operation of the electric motor M. The control means 100 is a valve, and the control means 100 controls the valve body 1.
The starting command is given so that the open state and the closed state are alternately switched as the motor rotates in the same direction, and each of the open state and the closed state appears multiple times during one rotation. The electric valve is configured to control the operation of the electric motor M so as to rotate the valve body 1 by a set angle each time the valve body 1 is rotated. 2. The control means 100 includes a power supply unit 21 that alternately reverses the polarity of conduction to the electric motor M each time a starting command is given; a rectifier D that rectifies the current so that the polarity of the current flowing to the rectifier D is the same as that of the current flowing polarity; Consisting of a first switch A that cuts off the connection between the rectifier D and the electric motor M, and a second switch B that cuts off the connection between the rectifier D and the electric motor M when the conduction polarity from the power supply section 21 is reversed. The motor-operated valve according to claim 1 of the claimed utility model registration.
