Abstract
Magnetic gearboxes an inner rotor and an outer rotor are known with pole members between them. However, these gearbox arrangements generally have a fixed gear ratio between the rotors. By provision of pole members with coils between them and associated switches to adjust the magnetic flux modulation capacity between the rotors it is possible to create open circuit, closed circuit and variable impedance configurations which will relatively passively adjust the magnetic flux modulation capacity or by presenting a voltage to the coils or drawing a voltage from the coils to more actively adjust the magnetic flux modulation capacity across the arrangement. In such circumstances a wider range of gear ratios is achieved as well as the capability with regard to localized electrical power generation through the gearbox arrangement or electro magnetic braking achieved upon the gear box as required.
