ABSTRACT:
The present invention relates to a rotary electrical machine comprising:at least one stator; andat least one rotor;the rotor having an axis of rotation and co-operating with the stator to define at least one airgap, the rotor comprising permanent magnets and pole pieces between the magnets;at least one pole piece being associated with one or more permanent magnets to concentrate the magnetic flux from said magnet(s); andsaid magnet(s) defining at least three different directions of magnetization, the resultant flux in the pole piece towards the stator being non-coplanar with at least two of the directions of magnetization.
