Abstract

PURPOSE:To reduce the diameter of a bearing box supporting a bearing while obtaining the compact small-sized motor by inserting the bearing into a box body from the direction opposite to a rotor. CONSTITUTION:With a bracket 29 at the non-load side forming one part of the box body, the stepped section 292 of the bearing box 291 is shaped in the direction of the rotor 3, and used as the contacting section of the bearing 5. On the other hand, the bearings 5, 7 are inserted into the bearing section 291 from an opening 298 at the side opposite to the rotor 3 of the bearing section 291. A screw hole 294 is formed to the bracket 29, and a bearing hold-down section 9 is mounted to the hole by a clamping screw 10, thus preventing movement in the axial direction of the bearings 5, 7 and a motor shaft 4. Accordingly, the outside diameter of the bearing box supporting the bearings can be reduced, and the compact small-sized motor can be obtained.
