ABSTRACT:
A stator assembly for a brushless DC permanent magnet motor or generator features an internal stator with electrical windings surrounded by a permanent magnet rotor. The stator assembly includes a collar member matingly interconnecting the stator core and the winding's power supply circuit board so as to automatically position them, during manufacture of the device, in predetermined angular and axial relationships with respect to each other, and in predetermined axial relationships with respect to the rotor. The collar member also contains an axial passageway which facilitates handling of the stator assembly during manufacture.
