ABSTRACT:
A magneto dynamic machine, which may be an electric motor not having a commutator, for example one having electronic commutation, has a permanent magnet rotor comprising a rotor shaft carrying a rotor body, the rotor being provided with permanent magnet elements. The latter consist of a plurality of segments of magnetic material, retained in position by clamping rings engaging around free ends of the magnetic segments. The space between each segment and the next is occupied by a spacing bar.
