Miniaturmotor

摘要

A miniature electric motor comprises a metallic case (31) formed into a bottomed hollow cylindrical shape, and on the inner circumferential surface of which a permanent magnet (32) is fitted. A rotor (34) with an armature (35) and a commutator (36) is supported in a bearing (37) in the case and a bearing (38) in a case cover (33) fitted to the open end of the case (31). Brushes (3, 39) in the cover (33) make sliding contact with the commutator (36) and input terminals (2, 41) are electrically connected to the brushes. One or more electronic components (7) are connected to the input terminals (2) and held in place by a spring member (9) made of an electrically conductive material.
