Abstract
An electric machine or assembly 10 including a housing 12, a stationary stator 14, two substantially identical and opposed rotors 16, 18, and a pair stationary field coils 22, 24. Field coils 22, 24 are selectively energizable to controllably vary the flux generated by assembly 10, thereby allowing assembly 10 to provide a relatively constant output torque, power, or voltage over a relatively wide range of operating speeds.
