Claims

[Claims for Utility Model Registration] A coil assembly formed by winding a coil around a bobbin,
A stator consisting of a yoke attached to this coil assembly is stacked and housed in a frame consisting of a first frame and a second frame, and a rotor rotatably supported by the frame is disposed inside the stator. In a stepping motor in which both frames are positioned and fixed, the first frame and the stator facing the first frame, the second frame and the stator facing the second frame. An engaging portion is formed on one of the frames, and an engaged portion that engages with the engaging portion is formed on the other, and these engaging portions and the engaged portion are engaged to connect both frames and the above-mentioned frames. A stepping motor characterized by positioning a stator.
