A motor/alternator is formed by a single toroidal magnet, which may be a hybrid magnet, having flux conductors which, in combination with flux switches, create an alternating magnetic circuit around a power coil. The motor/alternator minimizes the amount of material experiencing hysteresis by making the flux switches small and reduces eddy currents in the flux conductors by using a material very resistant to eddy currents. The subsequent reduction in core losses allows for very high electronic frequency operation and thus a high power density. The form of the flux conductors allows for a high number of poles in the motor/alternator thus enabling a high electronic frequency at modest rotational speed.
