Specific embodiment
For content of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following examples, and coordinate
Accompanying drawing describes in detail as follows:
Refer to Fig. 1, a kind of electric lost dental inlay permanent magnet brake, including ring gear 1, terminal pad 2, armature 3, permanent magnetism body disc 8
And yoke；Described ring gear 1 one side end face is provided with end-tooth, and described armature 3 is positioned at described ring gear 1 inner circumferential and solid with described ring gear 1
Connect, described terminal pad 2 is in axial sliding connection with described ring gear 1 and rotates with described ring gear 1；Described yoke includes inner yoke 6 He
Outer yoke 9, described outer yoke 9 includes disc portion a and cylindrical part a, and described inner yoke 6 includes disc portion b and cylindrical shape
Portion b, described cylindrical part a, described disc portion b and described cylindrical part b enclose annular groove, described permanent magnetism body disc 8
Between described disc portion a and described disc portion b and affixed with both, it is provided with coil 5 in described annular groove；Described rank
Ferrum 3 end face is provided with shoulder hole, is provided with stage clip 4, the shoulder end face of described shoulder hole in the in the hole being relatively large in diameter of described shoulder hole
It is connected with the end thereof contacts of described stage clip 4；It is cased with lead, described lead one end passes through described shoulder hole in described stage clip 4
Affixed with described terminal pad 2, the described lead other end is provided with shoulder, another termination of described shoulder end face and described stage clip 4
