ABSTRACT:
The stator core assembly for an electric motor, particularly such a motor in which operating characteristics of the motor is accomplished by means of a secondary coil, such as a choke coil. The stator core assembly comprises a plurality of laminations made of suitable magnetic material with the laminations assembled in a stack to form a core having a central bore extending longitudinally therethrough for the reception of a rotor of the electric motor and having a plurality of slots extending longitudinally through the core for receiving coils of wire which constitute the windings of the motors. Each of the laminations further has other openings therein so that upon the laminations being stacked in a core, the other openings form a receptacle for the reception of the above-mentioned secondary coil.
