  • Patent number: 6058593
    Abstract: A micro motor is manufactured by slipping the parts (24a, 24b) of a stator (24) on the mandrel (60) which is placed into an injection mold (50). The motor housing is made by injecting polymer material (63), the stator parts (24a, 24b) being encapsulated in the housing. During injection, a bearing (27) is contained in the injection mold (50). Subsequently, the mandrel (60) is drawn from the stator and a prepared rotor is inserted. Thus, a cost effective and high-precision manufacture of an electric motor with very small dimensions is made possible.
