Transverse regulated flux machine
A machine has a rotor to be associated with a shaft. The rotor is provided with permanent magnets. A stator has pole pieces, including a main winding and flux diverters separating the main winding from a control coil. Control is provided for controlling the power passing through the control coil. The machine is a transverse flux machine. The machine may be utilized as a generator, an electric motor, or for other application.
