Rotary electric motor having separate control modules for respective stator electromagnets

A rotary electric motor comprising:

• a permanent magnet rotor having a plurality of permanent magnets disposed in an annular ring configuration;
• and
• a stator coaxial with the rotor and separated therefrom by an axial air gap;
• wherein the stator comprises a plurality of independent stator units, each of the units comprising a ferromagnetically isolated core having a winding formed thereon and circuitry for controlling energization of the winding.
