Abstract

An electrical motor and method of manufacturing an electrical motor includes producing a stator having a yoke and a plurality of windings in magnetic communication with the yoke. A rotor is juxtaposed with respect to the stator to rotate in response to magnetic flux produced by the stator. A variable frequency power supply is connected with the windings in order to produce a magnetic flux with the stator. The yoke is made from a polymer bonded soft magnetic material that does not substantially increase in permeability in response to an increase in frequency of the power supply.
