METHOD FOR MANUFACTURING COMPACT MOTOR, COMPACT MOTOR, EQUIPMENT, APPARATUS AND TOOLS

摘要

PROBLEM TO BE SOLVED: To provide a compact motor capable of obtaining a high reliability against a grease leakage from a bearing at output side and the flowing of oil or the like from equipment at opponent side. SOLUTION: A compact motor 1 is designed to have a wall 14 on a bracket 10 with a fixed clearance along the surrounding of an output shaft 3 between a commutator 7 and a bearing 6. Thereby, when a grease is leaking from the bearing 6 at output side, or oil or the like is flowing from equipment at opponent side, their adherence to the commutator 7 and a brush 5 can be prevented, and abnormal wear of the brush 5 and deteriorated performance of the compact motor 1 can be prevented.
