Abstract: An electric machine has a stator with N posts. A rotor is mounted on bearings for rotary movement about an axis relative to the stator with an air gap between the rotor and stator. The bearings are pre-loaded axial thrust bearings or pre-loaded angular bearings. The pre-load forces are provided at least in part by magnetic attraction between the stator and rotor. The rotor has M poles. The values for N and M have the property that the greatest common divisor of N and M is four or more.
