Abstract
A rotor for an electrical alternator or motor is described. The rotor has a number of disc shaped, axially magnetized, permanent magnets separated by steel discs, and elongated pole shoes parallel to the rotor axis making up the rotor periphery. The pole shoes are fixed to appropriate steel discs to give pole-shoe polarities which alternate around the rotor periphery. In order to .[.allow starting as a motor.]. .Iadd.stabilize the machine.Iaddend., alternate pole shoes are divided near one end and fixed to the same steel discs as transversely adjacent pole shoes .[.to give a solid metal rotor section which gives starting by induction motor action, and forms a toothed wheel which runs at synchronous speed by reluctance motor action.]..
