Abstract:
An electrical machine includes a rotor comprising a rotor core and a plurality of permanent magnets embedded radially within the rotor core to form a plurality of rotor poles. The electrical machine further includes a stator comprising a stator core disposed concentrically outside the rotor and including a plurality of stator teeth defining a plurality of stator slots there between. An arithmetic sum or difference of twice the number of stator teeth and the number of the stator poles equals the number of rotor poles.
