Abstract:
An electric motor comprising:one or more laminations of a metallic material forming an outer casing of the electric motor; one or more circular non-metallic, flat, thermally conductive disks positioned between said laminations for conducting heat generated by an electrical current flowing within the motor through said conductive disks; an electrically conductive material wound in a plurality of layers within the laminations so as to form an electric field that drives an armature when an electrical current is applied, thermally conductive strips interleaved between preselected layers of the electrically conductive material, said thermally conductive strip extending outside of the area covered by the electrically conductive material; and means for conducting heat at the end of the non-metallic thermally conductive disk and the thermally conductive strips thereby cooling the motor.
