Abstract:
PCT No. PCT/EP98/01867 Sec. 371 Date Dec. 1, 1998 Sec. 102(e) Date Dec. 1, 1998 PCT Filed Mar. 31, 1998 PCT Pub. No. WO98/44619 PCT Pub. Date Oct. 8, 1998A 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.
