PERMANENT MAGNET ROTOR FOR A SYNCHRONOUS ELECTRICAL MACHINE, PARTICULARLY FOR A RELUCTANCE MOTOR

摘要

The rotor has N poles, where N is an even number, and comprises a stack (LS) of plates (L) of magnetic material, each of which has N adjacent angular sectors (1-4), in each of which is formed a corresponding plurality of cavities or apertures (C) in which there extend corresponding permanent magnetic elements (M) which are magnetized in each sector (1-4) in the opposite direction to those of the adjacent sectors, and which are formed from a magnetic material moulded in the apertures or cavities (C) of the stack (LS) of plates (L).
