ABSTRACT:
An electric motor comprises a laminated stator core supporting windings to define similar adjacent poles. A rotor is mounted to rotate within the stator. The similar poles in a group define flux paths with adjacent pole groups. Thus the flux paths required are restricted to those between adjacent dissimilar pole groups. In this way the material of the core between the flux paths can be reduced as it is not required to carry flux itself. This redundant portion of the core can be shaped to accommodate neighbouring components or to reduce the material of the core laminations.
