A compact, rugged, variable reluctance, variable speed, electric motor capable of producing high torque at high electrical energy conversion efficiencies is provided. The present invention provides for a multi-stage motor design having a number of discreet rotor and stator elements on a common shaft. This configuration provides for the simplest of magnetic structures and produces a powerful magnetic flux modelling design technique that is used to further optimize the motor design and subsequent control logic. Thermal mapping of the magnetic mass provides for advanced cooling techniques that are used to ensure long in-service life in the most extreme of industrial applications. The electric motor inherently provides low vibration thereby greatly reducing noise; low turn to turn voltage potentials thereby eliminating costly phase to phase shorting potential; efficient motor operation through the reduction in switching and copper losses in both the machine and its control system.
