1. A method for manufacturing a permanent magnet motor, said method comprising:
- fabricating a stator core to have a skew based on a least common multiple of a number of rotor poles and a number of stator teeth;
installing windings about teeth of the skewed stator core to generate a wound stator core; and
positioning a permanent magnet rotor with respect to the wound stator core.
