Claims

[Scope of utility model registration request]

An alternating current power source, a rectifier that converts the alternating current supplied by the alternating current power source into direct current, a triangular wave generation circuit that emits triangular waves, a mechanically driven device, and a control amount for driving the mechanically driven device. a control device that outputs an output, a drive circuit that generates a drive output by comparing and calculating the triangular wave and the control amount, and a drive that mechanically drives the mechanically driven device in accordance with the drive output from the drive circuit. A drive device using alternating current as a power source, characterized in that a triangular wave generated from the triangular wave generating circuit is synchronized with the frequency of the alternating current power source.
