Turn.
Described stator 1 includes casing 11 and is arranged on the permanent magnet 12 of casing 11 inwall, described in be loaded on the bearing on stator 1
4 bottoms being positioned at casing 11, described end cap 3 is fixedly mounted on the opening at casing 11 top, in the inner side of end cap 3 upper bearing (metal) 4
Pad is provided with stop tab 31, is equiped with some brushes 33 by brush holder 32 below end cap 3.
Described rotor 2 includes the rotating shaft 21 with bearing 4 interference fit, the sleeve pipe 22 being set in rotating shaft 21 and diverter
23 and the rotor core that is fixed in rotating shaft 21 between sleeve pipe 22 and diverter 23, described diverter 23 and brush 33
Contacting, connecting on diverter 23 has a varistor 24, is also associated with oil baffle 25 in the end of diverter 23；Described
Rotor core is by some stalloys 26 and is fitted in the insulating trip 27 of stalloy 26 both sides and forms, be wound with outside rotor core with
The enamel-covered wire winding 28 that diverter 23 connects.
This utility model simple in construction, reasonable in design, it is possible to be effectively improved the properties of permanent magnet DC motor, make motor
Work more stable.
