Permanent magnetism low speed generator

Disclosed is a permanent magnetism low speed generator, comprising a housing, an external stator, a rotor, and an internal stator, wherein the rotor is operated between the internal stator and the external stator, thus to make the double surfaces of the magnet be reasonably utilized and increase the number of pole pairs to make the generator reach low speed generating. The utility model, with simple structure and low cost, can be widely used for the generating with wind power, small hydro, or engine, and can be used in civil power shortage area.
