Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail: the present embodiment is implemented under premised on technical solution of the present invention, gives detailed execution mode, but protection scope of the present invention is not limited to following embodiment.
embodiment one:
As depicted in figs. 1 and 2, axial magnetic circuit one pole slotless deceleration type motor protecter, described axial magnetic circuit one pole slotless deceleration type motor protecter comprises non-magnetic stainless steel sleeve 1, permanent magnet 3 and two circular magnetic stainless steel baffle plates 2;
Described permanent magnet 3 is disc-shape, the permanent magnet 3 of disc-shape is installed in non-magnetic stainless steel sleeve 1, the magnetic circuit of the permanent magnet 3 of disc-shape is arranged vertically, described two circular magnetic stainless steel baffle plates 2 are fixed on the two ends in non-magnetic stainless steel sleeve 1, and circular magnetic stainless steel baffle plate 2 reclines mutually with two end faces of the permanent magnet 3 of disc-shape, the middle part of two circular magnetic stainless steel baffle plates 2 is respectively equipped with axis hole, the middle part of the permanent magnet 3 of disc-shape is also provided with axis hole, the axis hole of the axis hole of the permanent magnet 3 of described disc-shape and two circular magnetic stainless steel baffle plates 2 is coaxially arranged, during use, the output shaft 4 of described motor 6 passes the permanent magnet 3 of disc-shape and the axis hole of two circular magnetic stainless steel baffle plates 2, and be equipped with gap between the axle hole inner circle side face of the axle hole inner circle side face of the permanent magnet of disc-shape (3) and two circular magnetic stainless steel baffle plates 2 and the output shaft 4 of motor 6.
