STATOR PORTION FOR AN ELECTRIC MACHINE COMPRISING AN PERMANENT MAGNET ROTOR

摘要

A ferromagnetic core for a stator coil of a permanent magnet electric rotary machine, wherein the ferromagnetic core includes a compound including a polymer matrix composition and a functional filler, the functional filler including a material selected from ferromagnetic material, magnetic material, and a combination thereof. The ferromagnetic core includes at least one fluid channel extending through the core. A stator coil for an electric rotary machine, including a ferromagnetic core and at least one winding of a conductor wound around the core. A stator for an electric rotary machine, including a stator frame around a central axis, having an opening for receiving a fluid flow and stator coils. A permanent magnet electric rotary machine including a rotational shaft, a stator, a rotor connected to the rotational shaft, wherein the rotor is provided with permanent magnets, the permanent magnets facing the ferromagnetic cores of stator coils of the stator. The rotor includes ventilation means for in operation generating a fluid flow through the fluid channels of the ferromagnetic cores.
