Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1, the utility model comprises: comprise the stator 1 of circular arc, and circular-arc can be along the rotor 2 of stator 1 circular motion, rotor 2 is arranged on stator 1 inner side, or is arranged on stator 1 outside, forms outer-rotor structure.Referring to Fig. 2, stator comprises the stator hypomere arranging from the bottom to top, 1-3, stator stage casing 1-2, stator epimere 1-1, stator epimere 1-1, stator stage casing 1-2 radially offer respectively some grooves in same position, form dentalation, dentalation is along circular arc circular array, and stator stage casing 1-2 internal diameter is greater than the internal diameter of stator epimere 1-1,, form cannelure; Stator hypomere 1-3 is identical with stator epimere 1-1 internal diameter, but does not slot.In the groove of stator stage casing 1-2, being provided with by the first output winding 6 of groove coiling serial connection and the number of turn of the second output winding 5, the first output windings 6 and the second output winding 5 is linear distribution.1-2 outside in stator stage casing is also provided with excitation winding 4.Between stator 1 and rotor 2, leave gap, in rotor 2 rotation processes, between the endoporus of stator 1 and the cylindrical of rotor 2, form multistage air gap 3.
