The utility model solves the technical scheme that its technical problem adopted: a kind of hybrid excitation generator is used the pawl utmost point; The a plurality of pawl utmost points that comprise pawl utmost point body and be arranged on the pawl utmost point body refer to; Have on the said pawl utmost point body and be used for and the endoporus that cooperates of axle, the both sides that said each pawl utmost point refers to all have the magnet standing groove.
Have at least two positioning splines on the periphery that lays respectively at the pawl utmost point body of the adjacent pawl utmost point between referring on the said pawl utmost point body, these positioning splines are distributed on the circumference of pawl utmost point body, and positioning spline connects the two sides of pawl utmost point body.
Said each positioning spline refers to that with respect to endoporus, yoke end face and the pawl utmost point position degree of center line is 0.05mm.
Each magnet standing groove with respect to the position degree of endoporus, yoke end face and positioning spline less than 0.2mm.
The width of said magnet standing groove is than the long 0.2mm of the thickness of the permanent magnet of putting into it.
The cell wall of the contiguous pawl utmost point periphery of said magnet standing groove is 2.5~3.5mm to the distance of pawl utmost point periphery.
Said endoporus tolerance is 0.018mm.
The yoke end face of the said pawl utmost point and the perpendicularity of endoporus are 0.03mm.
Said pawl utmost point periphery is 0.02mm with respect to the axiality of endoporus.
The beneficial effect of the utility model: the utility model has solved the defective that exists in the background technology, has the magnet standing groove in the both sides that the pawl utmost point refers to, is formed for placing the magnet groove of permanent magnet after the assembling of the front and back pawl utmost point, has guaranteed the stability of permanent magnet position; Pawl utmost point body is provided with positioning spline, and the width of the magnet groove that pawl utmost point assembling back forms before and after having guaranteed conforming also is convenient to realize the automation of assembling simultaneously, can not only enhance productivity, can also labor savings.

Embodiment
A kind of hybrid excitation generator shown in Fig. 1~6 is used the pawl utmost point, comprises pawl utmost point body 1 and a plurality of pawl utmost points of being arranged on the pawl utmost point body 1 refer to 2.Have on the said pawl utmost point body 1 and be used for and an endoporus 3 that cooperates.Said each pawl utmost point refers to that 2 both sides all have the magnet standing groove 2-1 of a similar keyway, and the width of this magnet standing groove 2-1 is than the long 0.2mm of the thickness of the permanent magnet of putting into it 11.Pawl utmost point assembling back, front and back forms the magnet groove of hollow, and permanent magnet 11 just is embedded in this magnet groove, leaves certain clearance all around, is convenient to install.Need soak insulating paint at the assembling process rotor, insulating paint is penetrated in the slit, just tightly combines permanent magnet 11 with the pawl utmost point after solidifying.The quantity of this magnet groove is confirmed according to the power output of generator, but must is even numbers.The cell wall 2-11 of the contiguous pawl utmost point periphery 4 of said magnet standing groove 2-1 is 2.5~3.5mm to the distance of pawl utmost point periphery 4; This thickness has enough intensity to resist the centrifugal force of permanent magnet 11 in the rotor high-speed rotation; Add the magnetive attraction of permanent magnet 11 self; Thereby when the generator amature high speed rotating, guaranteed that permanent magnet 11 is not loosening.
When rotor assembled, the front and back pawl utmost point matched with axle through endoporus 3, and the front and back pawl utmost point tightly fits together yoke end face 5 through ambient pressure, so the endoporus 3 of the pawl utmost point is benchmark of processing magnet groove with yoke end face 5.In addition; The consistency of the width of each the magnet groove that forms for pawl utmost point assembling back before and after guaranteeing and be convenient to assembly automation; Have at least two on the said pawl utmost point body 1 and lay respectively at the adjacent pawl utmost point and refer to the positioning spline 1-1 on the periphery of the pawl utmost point body 1 between 2, this case preferred embodiment: positioning spline 1-1 is provided with two.This two positioning spline 1-1 is distributed on the circumference of pawl utmost point body 1, and positioning spline 1-1 connects the two sides of pawl utmost point body 1.Positioning spline 1-1 is an auxiliary base, guarantees the position degree between this auxiliary base and each the magnet groove.
Said endoporus 3 tolerances are 0.018mm; The yoke end face 5 of the said pawl utmost point is 0.03mm with the perpendicularity of endoporus 3; Said pawl utmost point periphery 4 is 0.02mm with respect to the axiality of endoporus 3; Said each positioning spline 1-1 refers to that with respect to endoporus 3, yoke end face 5 and the pawl utmost point position degree of center line 6 is 0.05mm; Each magnet standing groove 2-1 with respect to the position degree of endoporus 3, yoke end face 5 and positioning spline 1-1 less than 0.2mm.
Should be appreciated that specific embodiment described above only is used to explain the utility model, and be not used in qualification the utility model.By the spirit conspicuous variation of being extended out of the utility model or change and still be among the protection range of the utility model.
