An axial pole motor includes a stator (9) and a rotor (3) which face one another across a plane perpendicular to the rotor axis, the stator having coil windings (12) substantially uniformly circumferentially spaced and lying in planes substantially perpendicalar to the rotor axis defining a number of stator poles (11), the rotor also including a number of rotor poles (4) comprising one or more permanent magnets. The number of stator poles (11) is different to the number of rotor poles (4) and the stator poles (11) and rotor poles (4) are of substantially the same size and shaped to provide a pole overlap pattern in which when any one rotor pole completely covers a facing stator pole, the difference between the number of rotor poles and the number of stator poles which exist between that rotor pole and the next rotor pole which completely covers a facing stator pole is one.
