摘要:
An armature for a permanent magnet brushed motor includes a shaft, a number of silicon steel laminations circumferentially around the shaft, a commutator adjacent to an end of the shaft, and an enameled wire winding wound around the silicon steel laminations and the commutator. A plastic sleeve capable of withstanding high temperature is disposed between the commutator and the silicon steel laminations and adjacent to the commutator. A plastic member wraps around where the enameled wire winding winds the commutator, and fixedly attaching to the plastic sleeve. As such, the plastic member establishes a first point of attachment at where the enameled wire winding winds the commutator and a second point of attachment to the plastic sleeve. The problem of the enameled wire winding being loosed or broken due to the armature's high-speed rotation is prevented, thereby enhancing the motor's robustness and operational life.
