An electric motor design is described including coaxial, concentric multiple cylindrical stators and rotors with air gap registration maintained and rotor rotation and fixed stator position facilitated by use of one or more precision bearings mounted on a common shaft. The multiphase stator winding routing is facilitated by the use of multilayer printed circuit boards to allow multiphase excitation of the stator winding to provide induction motor drive to the rotor. The rotor is a double squirrel cage design that allows supplemental resistors and inductors to augment the construction materials inherent physical resistance and inductance of the squirrel cage. The design is further enhanced for high torque startup by construction superposition of a reluctance motor feature incorporated into the squirrel cage rotor construction. |
