Description
Technical field
The utility model relates to a kind of frequency control AC brake motor.
Background technology
The rotating speed of three-phase asynchronous motor rotor is lower than the rotating speed of rotating magnetic field, rotor windings is induced electromotive force and electric current because there is relative motion between magnetic field, and produces electromagnetic torque with magnetic field interaction, realizes energy conversion, threephase asynchronous runnability is good, and can save various material.
Frequency control AC brake motor can be widely used in the industries such as light industry, weaving, machine driving, plating production line, and all requirements need speed governing, the equipment of fast braking, accurately location is all applicable to using this serial braking motor;
In use brake is not inhaled, and has serious vibration and shriek, friction disc wear, working clearance increases, and moment declines, and the slow-speed of revolution operates steadily poor with unfailing performance, higher starting torque cannot can be obtained under less starting current, be not easy to safeguard, motor motor surface temperature when the long-time running of slow-speed of revolution permanent torque is higher, exceedes electric machine temperature rise value, there is certain potential safety hazard installed surface out-of-flatness, rigidity is poor, easily causes bearing damage, reduction of service life.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of slow-speed of revolution to operate steadily, reliably, without torque pulsation, can obtain the frequency control AC brake motor of higher starting torque under less starting current.
The utility model solves the technical scheme that its technical problem adopts: a kind of frequency control AC brake motor, there is body, the middle position of described body is provided with power shaft, the outer surface of body is provided with cooling blower, power shaft is provided with armature card and electromagnet, movable gap delta is provided with between armature card and electromagnet, the screw rod be fixedly connected with by nut is provided with between armature card and electromagnet, between screw rod, position is provided with lock nut, is provided with tripping spring between lock nut and armature card.
Further, the top of described body is provided with suspension ring and hand release.
Further, described nut often revolves 60 ° of advance 0.10-0.15mm.
Further, the surface of described body is provided with insulating barrier.
The beneficial effects of the utility model are: the utility model slow-speed of revolution operates steadily, reliably, without torque pulsation, can can obtain higher starting torque under less starting current, easy to maintenance, independently-powered cooling blower is to motor surface forcing functions, ensure that motor temperature rise when the long-time running of slow-speed of revolution permanent torque is no more than permissible value, install firm, solid, good rigidity, installed surface is smooth, can not bearing damage be caused, improve useful life.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. bodies, 2. power shaft, 3. cooling blower, 4. armature card, 5. electromagnet, 6. screw rod, 7. lock nut, 8. tripping spring, 9. nut, 10. suspension ring in figure, 11. hand releases, 12. insulating barriers.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of frequency control AC brake motor as shown in Figure 1, there is body 1, the middle position of described body 1 is provided with power shaft 2, the outer surface of body 1 is provided with cooling blower 3, power shaft 2 is provided with armature card 4 and electromagnet 5, movable gap delta is provided with between armature card 4 and electromagnet 5, the screw rod 6 be fixedly connected with by nut 9 is provided with between armature card 4 and electromagnet 5, between screw rod 6, position is provided with lock nut 7, tripping spring 8 is provided with between lock nut 7 and armature card 4, the top of body 1 is provided with suspension ring 10 and hand release 11, nut 9 often revolves 60 ° of advance 0.10-0.15mm, the surface of body 1 is provided with insulating barrier 12.
Distance movable between concrete armature card 4 and electromagnet 5 is called gap delta, and normal working clearance δ controls at 0.2 ~ 0.3mm, is maximumly no more than 0.5mm.After motor runs a period of time, because friction disc wear makes gap width increase, after exceeding maximal clearance, the normal adhesive of ac brake and braking will be affected, must adjust; With substitutes such as the iron sheets of similar thickness, nut 9 often revolves 60 ° of 0.15mm that about advance, and gap adjustment 3 must be even, otherwise can affect brake adhesive and braking, can burn out coil time serious; After motor uses a period of time, after friction disc wear, tripping spring 8 is slightly relaxed, and braking moment relatively slightly declines, and does not have large impact as used, can be motionless.As felt, moment declines to some extent, when need increase braking moment, can by lock nut 7 evenly precession about 180 ° forward, a maximum circle, can not be too many, due to braking moment too conference cause adhesive difficulty, or send unpleasant to hear electromagnetic sound, serious meeting burns out coil.If need reduce braking moment, then lock nut 7 is unscrewed 180 ° backward, a maximum circle, otherwise moment is too little, no matter moment is turned down or tuned up all will be readjusted gap.
Above-mentioned execution mode is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection range of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection range of the present utility model.
