ABSTRACT:
A motor having a stator and a rotor housed in a U-shaped cylindrical case. The cylindrical case has a connector bushing fitted at one end, and an opening at the other. Located on the periphery of the opening is a cylindrical support that projects inside the cylindrical case. A ball bearing is fitted inside the cylindrical support. A shaft is inserted into the opening and one end of the shaft is supported in the bearing. The other end of the shaft is supported in another bearing, which in turn, is mounted in a bearing bushing housed in the cylindrical case. One end of the stator touches a step of the inner circumference of the case, thereby fixing the position of the stator in the axial direction. One end of the inner circumference of the stator is fitted to an outer circumference of the cylindrical support, thereby fixing its position in the radial direction. Two rotor cores are mounted on the shaft. The gap between the stator core and the rotor cores is approximately 40-50 microns. The connector is integrated with the connected bushing.
