3. armature spindle 4. stator cores
5. stator winding 6. front end housings
7. rear end cap 8. fore bearings
9. oil sealing 10. fans
11. rear bearing 12. plane brake mounts
13. brake material 14,14 '. brake silpper
15. 16. fens magnet of compression spring
17. conical surface brake mount
Embodiment one
As shown in Figure 1, this solid rotor side magnetic braking threephase asynchronous machine is mainly by casing 1, solid rotor 2, armature spindle 3, stator core 4 and stator winding 5 are formed, the two ends of casing 1 are respectively equipped with front end housing 6 and rear end cap 7, it is protruding that the output shaft head of armature spindle 3 passes front end housing 6, and be provided with fore bearing 8 and oil sealing 9 between the front end housing 6, the other end passes rear end cap 7 backs fan 10 is installed, and be provided with rear bearing 11 between the rear end cap 7, solid rotor 2 is fixed on the armature spindle 3, stator core 4 and stator winding 5 are solidly fixed with casing, plane brake mount 12 is fixed on the casing inboard, has a circle annular stop material 13 on it, brake silpper 14 can be sleeved on the armature spindle 3 by compression spring 15 with moving axially, and be provided with branch magnet 16 between the solid rotor 2, this minute, magnet was fixed on the armature spindle 3, and the frictional fit face between brake silpper 14 and the plane brake mount 12 is the plane.
Because brake silpper can move axially, when electrical power, the elastic force that divides magnet generation magnetic force absorption brake silpper to overcome the compression spring separates with the plane brake mount, motor runs well, when motor cuts off the power supply, divide the magnetic force of magnet to disappear, the elastic force of compression spring makes brake silpper and plane brake mount friction catch, thereby motor is stopped operating.After this motor was used in crane, the impact phenomenon during startup had very significantly improvement, and the soft start effect can prolong the useful life of crane and associated mechanical transmission mechanism.In addition, its energy-saving effect is also very obvious.
