A rotary motor comprising an annular rotatable bearing having an inner surface having a diameter equal to or greater than 0.5 meters and an outer surface, the bearing including a plurality of magnetic rotor teeth elements positioned around a circumference of the outer surface and a stator including a plurality of permanent magnets and a plurality of energizable coils, the stator mounted separately from and positioned with respect to the bearing such that the plurality of rotor teeth elements of the bearing are radially proximate to the permanent magnets of the stator. Upon application of alternating current in a flux switch pattern in the plurality of energizable coils of the stator, torque is applied to the plurality of magnetic rotor teeth elements.

Large diameter rotary motor driven by flux-switching

A method for sanitizing an electric motor is provided. The method includes setting operational parameters for the electric motor for destroying targeted microbes; and energizing the electric motor using the set operational parameters. Computer program products and an electric motor are disclosed.
