Motor with stator formed from stator motorettes and compression spacers for increased heat transfer efficiency

An electric motor, comprising:

• a stator;
• and
• a rotor rotatably mounted in the stator;
• the stator including:
• a plurality of motorettes, each including a ferrous metal core segment, and a conductive winding on the core segment, the plurality of motorettes being arranged in a circular arrangement,
• a plurality of wedges that each include a non-tapered radially outermost surface that is wider than a pointed radially innermost surface, one of the wedges being positioned in each interface between the conductive windings of adjacent ones of the motorettes that presses the conductive windings of the adjacent ones of the motorettes towards respective ones of the ferrous metal core segments, wherein the plurality of wedges each include two winding contact sides that extend between a radially outer end and a radially inner end, and the radially inner end includes the pointed radially innermost surface which is radially aligned with a radially inner surface of the plurality of motorettes;
• an electric insulator on each of the ferrous metal core segments, the conductive windings being wound on the electric insulator;
• and
• a potting material surrounding the conductive windings.
