Inwall in described rotary shell is fixed symmetrically six to amount to 12 for suppress tooth harmonic wave electromotive force output voltage waveforms to produce distortion and eliminates magnetic pole surfaces loss and tortuous leakage reactance magnetic pole as permanent magnetism rotor.
Connecting described rotary shell 1 by the axle body coupling end of power shaft, driven rotary housing rotates, and permanent magnetism rotor is around generating winding relative movement.
Described stator core 3 is provided with the fixed orifices 8 being no less than 2, does not deflect for fixing described stator core. Described stator core 3 can be fixed on the surface of power shaft body by fixed orifices 8, and axle body with power shaft does not come in contact.
Described stator core 3 is obtained by silicon steel, and described stator core 3 is become by multi-disc silicon steel plate stacking.
The wire casing number scope of described stator core 3 is: 18��72.
The surface of described rotary shell is provided with multiple through hole. The through hole of any number can be set, for the heat radiation of generator.
The number of phases of described generating winding is single-phase or three-phase.
It is to be understood that, although this specification sheets is described according to enforcement mode, but not each enforcement mode only comprises an independent technical scheme, this kind of narrating mode of specification sheets is only for clarity sake, those skilled in the art should by specification sheets integrally, technical scheme in each enforcement mode through appropriately combined, can also form other enforcement modes that it will be appreciated by those skilled in the art that.
A series of detailed explanation listed above is only the concrete explanation implementing mode for feasibility of the present utility model; they also are not used to limit protection domain of the present utility model, all do not depart from the utility model skill equivalent enforcement mode of doing of spirit or change all should be included within protection domain of the present utility model.
