ABSTRACT:
An electric motor comprises a stator fixedly mounted to a shaft and a rotor, surrounding the stator, rotatably mounted to the shaft. The shaft is stiffened by a plurality of plates mounted to the shaft and held thereon under significant compression by a lock nut. The compression is high enough to inhibit bending that would otherwise occur from external forces acting on the shaft. The plates also form the windings for the motor.
