Abstract

PURPOSE:To enable to freely change the size of the bearing and the shaft for the subject motor by a method whereing a cylinder is fitted to the void located inside a stator, the section exposed to the outside of the stator is widened in diameter and the bearing is placed in this widened section. CONSTITUTION:The mounting plate 2, whereon a mounting hole 2A and a lead wire outlet hole 2 are provided, has a cylindrical section 2C, having the base section of a large diameter and the point section of a small diameter. The outer circumference of the small diameter section of the cylindrical section 2 is fixed to the inner void 4A of the stator core 4 having a stator coil 3 and the bearing 6 is arranged on the inside of the large diameter section. Through these prodecures, the size of the bearing 6 and the rotor shaft 1 can be changed without changing the shape of the stator core 4.
