ABSTRACT:
A motor is equipped with a magnetic structure, stator assemblies having a non-magnetic molding member for being incorporated in the magnetic structure and coils for being wound on the outer periphery of each stator assembly.
The magnetic structure is provided with magnetic pole plate bodies, a recess provided in each magnetic pole plate body, bridge members incorporated in the magnetic pole plate body in such a manner as to surround the recess and a plurality of terminal elements whose base ends are coupled to the bridge members and whose free ends are extended toward the recess. The recess, together with the free ends of the terminal elements, is filled with the non-magnetic molding member. On the other hand, the bridge members are not embedded with the non-magnetic molding member but are subsequently cut and removed, so that the base ends of the terminal elements are arranged in such a manner as to project from the surface of the non-magnetic molding member.
