Abstract
The invention relates to an additional direct current electromagnet brake electromotor. The additional direct current electromagnet brake electromotor comprises a stator and a rotor. The stator is installed above the rotor. An end cover is installed in front of the stator and the rotor. The additional direct current electromagnet brake electromotor has the advantages of being small in size, light in weight, stable and reliable in operation, large in brake torque, high in brake speed, accurate in locating and convenient to maintain.
Description
Technical field
The present invention relates to a kind of motor, particularly a kind of additional DC electromagnet brake motor.
Background technology
The direct current disc brake of electromagnetic brake motor is arranged on the end cap of motor non-shaft stretching end.When brake motor access power supply, brake is also worked simultaneously.Due to electromagnetic attraction effect, electromagnet attracts armature Compress Spring, and brake disc is thrown off in armature end cap, motor entry into service.When cutting off the electricity supply, brake electromagnet loses magnetic attraction, and spring promotes armature and compresses brake disc, and under rub-moment effect, motor shuts down immediately.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of volume little, lightweight, operate steadily reliable, braking moment is large, retro-speed is fast, accurate positioning, motor easy to maintenance.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of additional DC electromagnet brake motor, comprise stator and rotor, and described stator is arranged on the described stator in top of rotor and the place ahead of rotor is provided with end cap.
The invention has the beneficial effects as follows: volume is little, lightweight, operate steadily reliable, braking moment is large, retro-speed is fast, accurate positioning, easy to maintenance.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the place ahead of described end cap is provided with brake disc, and described brake disc top is provided with baffle plate.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the place ahead of described brake disc and baffle plate is provided with armature.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the place ahead of described armature is provided with electromagnet.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the place ahead of described electromagnet is provided with and automatically terminates device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In accompanying drawing, the list of parts of each label representative is as follows:
1, nail, 2, rotor, 3, end cap, 4, brake disc, 5, baffle plate, 6, armature, 7, electromagnet, 8, automatically terminate device.
Embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of additional DC electromagnet brake motor, comprises stator 1 and rotor 2, and described stator is arranged on the described stator in top of rotor and the place ahead of rotor is provided with end cap 3.The place ahead of end cap is provided with brake disc 4, and described brake disc top is provided with baffle plate 5.The place ahead of brake disc and baffle plate is provided with armature 6.The place ahead of armature is provided with electromagnet 7.The place ahead of electromagnet is provided with and automatically terminates device 8.
While switching on power, electromagnetic brake magnet exciting coil is also connected DC power supply simultaneously, and electromagnetic attraction by armature suction _ L, makes spring-compressed immediately. and the braking surface of brake disc and back end cover for motor and armature are thrown off, and rotor and fan and brake disc rotate together with just; The rear brake of cutting off the electricity supply is power-off simultaneously also, and electromagnet loses electromagnetic attraction, and spring promotes armature immediately makes merit dish processed contact with rear end cap, produces friction torque rotor is checked rapidly.As need brake off. with release lever, insert in release aperture and move axially; After extracting release lever, just recover braking.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., all should be included in protection scope of the present invention.
