Abstract

A motor or generator comprises a rotor comprising an axially directed magnet having end mounted radially facing poles, the poles being circumferentially off-set. Respective stator pole assemblies face the rotor poles, the stator poles carrying windings. A design of the stator/rotor teeth is disclosed, fig 18 and the stator/rotor assembly may form a module, fig 20, successive modules being arranged with like poles adjacent. End magnets, figs 22, 22a, may be included to prevent flux leakage. The machine may have up to 48 rotor teeth and 48 windings per rotor pole allowing the machine in the generating mode to be driven by a slow speed power source eg spring or wind power.
