Claims

[Claims for Utility Model Registration] 1. An AC motor whose rotational speed changes according to the frequency of the power source, an output shaft driven by this AC motor, and an outer diameter that corresponds to the frequency ratio of the different power sources to be used. A plurality of driving wheel bodies are connected to each other in a concentric manner on the output shaft in a manner in which the ratio is set, and are removably fitted in a state in which rotation is stopped in a concentric circle on the output shaft, and one of the driving wheel bodies and a driven wheel body are wound around A rotary drive device characterized by consisting of a rotated endless band. 2. An input shaft driven by an AC motor whose rotation speed changes depending on the frequency of the power supply, and an output shaft connected to a driven part and rotatably provided in parallel to the input shaft, each having a different number of teeth. a plurality of input gears arranged in the axial direction and fixedly fitted to the input shaft; and a plurality of input gears arranged in the axial direction and fixedly fitted to the output shaft, and different gears for use. a plurality of output gears each having a number of teeth matching a gear ratio corresponding to a frequency ratio of a power source and selectively meshing with one of the input gears; and at least one of the input gear and the output gear. A rotary drive device comprising a speed change operation means for shifting in an axial direction.
