動機の始動装置。[Scope of Claim for Utility Model Registration] 1. In a capacitor run single-phase induction motor, a starting capacitor is added in addition to the operating capacitor, and the starting capacitor is connected in parallel to the operating capacitor for a very short period of time during startup. A starting device for a small electric motor, characterized in that when used, torque at starting is increased only during extremely low shaft rotational speeds. 2 Claims for Utility Model Registration Paragraph 1 states that the circuit cutoff switch of the starting capacitor is configured to utilize the magnetism of the motor core so that the movable iron piece of the switch is attracted to the stator core of the motor. This is a starting device for small electric motors.
