| 摘要 |
An economical, miniature electric motor exhibiting improved efficiency and in-specification, first-use performance after substantial periods of non-use, which is especially suited for operating the film eject mechanism of a self-developing camera, includes single piece, base metal brushes, a plain bore armature bearing in the commutator end cap, and a fibrous wicking material containing a supply of commutation enhancing lubricant bearing against the commutator to provide a supply of the lubricant thereto which minimizes brush friction while enhancing electrical conduction therebetween. Additionally, migration of the commutator lubricant along the rotor shaft into the plain bore journal in the motor end cap is encouraged to provide a supply of surface lubricant for the journal.
