ABSTRACT:
An electric motor is provided with a multi-layered winding stator core configuration. A plurality of individual layers of wire strands are successively formed on each stator pole of a pole pair. Each winding layer is fabricated of the same relatively thin wire gauge. A first layer is applied directly on a pole and each successive layer is assembled on top of the last previous layer. Each layer of one pole of the pole pair is connected in series with a layer of the other pole of the pole pair to obtain a number of individual series coil connections equal in number to the number of layers. As inductance and resistance characteristics of the layers differ from each other as the layers increase in distance from each pole, layers from one pole of the pole pair are connected to respective layers different in order from that of the other pole pair.
