ABSTRACT:
An electric motor having a circular stator with angularly spaced, radially inwardly extending teeth that define winding slots therebetween. The teeth inner ends define a bore whereat the motor rotor is located. The stator is made of a plurality of bound laminations of magnetically permeable material. The end lamination includes tab portions between the stator teeth which are punched out of the same stock material during the punching process and which are, thereafter, bent to extend away from the stator. The bent tab portion provided a resting ledge whereat wire extending between the coils on the stator teeth extends over and is retained away from the rotating rotor. The tabs further aid in properly locating the wire from coil to coil during the winding process. The tab portions have a rounded, semi-circular end part to prevent the snagging and possible damage of the wire during the initial winding process.
