Modular electrical machine

Markus Anton Mueller (Inventor), Alasdair Stewart McDonald (Inventor)

Research output: Patent


A modular electrical machine includes multiple integrated rotor modules releasably mounted upon a power transmission member to form a torus-like structure, wherein each integrated rotor module includes a series of parallel rotor plates spaced apart to provide an air gap between successive rotor plates in the series. The rotor plates hold permanent magnets securely within the air gap. Corresponding stator modules, each made of multiple air-cored coils potted in a resin material to form a blade. Each blade is externally supported with respect to the rotor module and is positioned between the permanent magnets within one of the air gaps between successive rotor plates.
