Claims

[Scope of utility model registration request]

(1) In an axial gap type flat coreless motor, there is a flat cylindrical motor case, a field magnet fixed to the inner surface of one axial end of the case, and the magnet and the other axial end surface of the case. and a rotor having a disk-shaped coreless armature fixed to the rotating shaft with a gap therebetween, and a circular magnetic plate between the inner surface of the other axial end of the case and the armature. A flat coreless motor characterized by being equipped with.

(2) Utility Model Registration Scope of Claims 1. The flat coreless morph according to claim 1, wherein the magnetic plate extends from a circle on its circumferential surface to a position where the diameter is approximately equal to the inner circumferential diameter of the case. A plurality of extending engaging claws are provided, and the engaging claws are brought into contact with the inner circumferential surface of the case to fit and fix the magnetic plate to the case.
