Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.
As shown in Figure 1, the utility model discloses a kind of speed governing electromagnetic braking motor, comprise load motor 10, brake assembly, velocity package, the blade cover 40 of the fan blade 30 of heat transmission and protection, the axle of load motor 10 is armature spindle 20.
Brake assembly comprises that the brake seat 51 that is provided with installing hole, some springs 52, some hexagon prism 53(present embodiments adopt four hexagon prisms), be provided with friction seat 54, friction plate 55 and the brake(-holder) block 56 of spline groove, brake seat 51 outer rings are provided with spring eye, spring 52 is installed in the spring eye, hexagon prism 53 1 ends pass installing hole brake seat 51 are fixed on load motor 10 bottoms, the other end is placed in the spline groove of friction seat 54, friction plate 55 is bonded on the friction seat 54, and brake(-holder) block 56 is locked on the armature spindle 20.
Velocity package comprises velocity coils fixed head 61, velocity coils 62, magnet ring 63 and speed control test the speed, velocity coils fixed head 61 is fixed on hexagon prism 53 ends, velocity coils 62 is installed on the velocity coils fixed head 61, the magnet ring 63 that tests the speed is locked on the armature spindle 20, and speed control can be set the rotating speed of load motor 10 according to the voltage that velocity coils 62 produces.The fan blade 30 adjacent magnet rings 63 that test the speed, and be locked on the armature spindle 20.Fan blade 30 gets close to the magnet ring 63 that tests the speed, and can utilize the space of fan blade 30 and the external diameter difference of velocity coils 62 fully, makes the airflow smooth of fan blade 30, and radiating effect is better.
The process of its installation is as follows:
Four hexagon prisms 53 pass the installing hole of brake seat 51 correspondences, the bottom of brake seat 51 being close to load motor 10, put several springs 52 in the spring eye that bores in brake seat 51 outer rings, the spring force size is according to the braking force adjustment, friction plate 55 is bonded on the friction seat 54, and the end of four hexagon prisms 53 just in time is placed in the spline groove of friction seat 54.Lock brake(-holder) block 56 at armature spindle 20, velocity coils fixed head 61 is screwed four hexagon prism 53 ends, lock the magnet ring 63 that tests the speed at armature spindle 20, fixing velocity coils 62 again, lock fan blade 30 at the adjacent magnet ring 63 that tests the speed, the blade cover 40 of protection is installed at last, has just been finished the assembling of this speed governing electromagnetic braking motor.This installation can allow heavier brake seat 51 be close to electric machine casing bottom, the part cantilever of other lighter weight in the back, the center of gravity of overall part is near the end face of screw locking.In frequent braking, be not easy to cause the loosening of screw.Make that the quality of product is more reliable.
The implementation process of the electro-magnetic braking functions of this utility model is as follows: when its implementation process is load motor 10 rotations, coil in the brake seat 51 gets, friction seat 54 is attracted, make friction plate 55 and brake(-holder) block 56 break away from, load motor 10 freely rotates.When load motor 10 stops, coil losing electricity in the brake seat 51, friction seat 54 is pushed to brake(-holder) block 56 by spring 52, make friction plate 55 and brake(-holder) block 56 rub, because friction seat 54 blocks four hexagon prisms 53, can not rotate, brake(-holder) block 56 is locked on the armature spindle 20, brake(-holder) block 56 is by friction plate 55 friction ecelerations, so also retarding braking of rotor.
