Abstract:
Electrodynamic apparatus, comprising:a stator subassembly including a plurality of spaced apart stator core members configured as extending from a stator backiron, said stator cores and stator backiron being integrally formed of magnetically soft pressure shaped processed ferromagnetic particles which are generally insulatively associated, said stator core members and stator backiron being disposed about an axis, a plurality of stator windings extending about corresponding said stator core members at winding core portions and extending thereon to core flux interaction portions, and two or more winding leads extending from said plurality of stator windings to respective exit termini; an encapsulation structure formed around said stator subassembly of molded rigid injection moldable thermoplastic surrounding at least said stator windings and the space between said windings, having a central opening region disposed about said motor axis extending from a rotor operational region and configured having one or more shaft bearing mounts integrally formed therein and symmetrically disposed about said axis; one or more shaft bearings mounted upon corresponding said bearing mounts; a shaft mounted with said one or more shaft bearings for rotation about said axis and extending into said rotor operational region; and a rotor within said rotor operational region, mounted for rotation with said shaft and defining a working gap with said core flux interaction portions.
