Abstract
A brushless electrical machine has a stator assembly with spaced coils and a rotor assembly with spaced permanent magnets and with axial air gaps between the assemblies. The magnets define rotatable flux-producing modules and the coils are in positions adjacent to the paths of travel of the magnets. The machine can be operated as a low speed, high torque motor or as a low speed, high power output generator with output characteristics proportional to the number of axially interleaved stator and rotor assemblies.
