DIRECT CURRENT MOTOR

摘要

A motor includes a shaft, at least one bearing, a rotor, a stator, and a brush carrier. The bearing is located adjacent to the shaft. The rotor is interconnected to the shaft and magnetically interacts with the stator. The brush carrier is releasably interconnected to the rotor and/or stator such that the brush carrier can mechanically disconnect from the rotor and/or stator without disturbing a bearing and other motor elements. By disconnecting the brush carrier from an endbell and viewing the commutator surfaces through an endbell aperture, the commutator surfaces of the motor are inspected. Since more than one winding portion of the armature can act as a commutating surface, motor assembly is simplified and the motor has a long useful life. A motor including more than one brush carrier is also provided. Each brush carrier is releasably interconnected to the rotor and/or stator such that either brush carrier can be mechanically disconnected from the rotor and/or stator without disturbing other motor elements.
