  • Patent number: 4156822
    Abstract: A stator core lamination and a rotor core lamination for a dynamoelectric machine are formed from the same lamination blank. The stator core lamination has a series of operations performed on it, preferably during the punch press manufacture of the laminations. Those operations enable a stator core, formed from the stator laminations, to receive a rotor core, formed from the rotor laminations, without any machining steps being performed on either core in order to accomplish the reception. The stator lamination includes a yoke section having a central rotor receiving bore opening formed in it. A plurality of slots extend radially outwardly from the bore opening. That area of the lamination between adjacent slots define a plurality of stator teeth. The teeth include a root section attached to the yoke and a stem having an inboard face delimiting the bore opening. The yoke and teeth initially lie in and define a first physical plane area.
