Claims

[Claims for Utility Model Registration] (1) A stator comprising a field having a plurality of N and S magnetic poles, which faces the field through an axial gap and is rotatably supported. In an axial gap type flat motor equipped with a coreless flat armature consisting of a group of coreless armature coils, when the coreless flat armature rotates, the coreless flat armature rotates eccentrically and vibrating. A vibrating axial gap type flat electric motor comprising a weight provided at a predetermined location of a coreless flat armature and on the opposite surface facing the field. (2) The vibrating axial gap type flat electric motor according to claim (1) of the utility model registration, wherein the weight is a magnetic material. (3) The vibrating axial gap type flat electric motor according to claim 1 or 2 of the utility model registration claim, wherein the armature coil is an air-core armature coil. (4) The vibrating axial gap type flat electric motor according to claim (3), wherein the air core type armature coil group is arranged at equal intervals so as not to overlap each other. (5) The above-mentioned weight is a vibrating type axial type according to claim 3 or 4 of the utility model registration claim, which is integrated at the same time as the armature coil group is molded with plastic. Air gap type electric motor.
