Abstract
The utility model discloses a brake control device of a direct current tubular motor. The brake control device comprises a brake disc and a brake coil that are fixed inside a casing. A brake sheet is pushed by a brake spring to be movably arranged between the brake disc and the brake coil. The brake disc is connected with an output shaft of a direct current tubular motor. The brake coil is connected with a brake control module. The brake control device allows connection and disconnection of the brake sheet and the brake disc to be controlled individually. Under control of the brake control module, when electricity is supplied to the brake coil, suction is generated by the brake coil to suck back the brake sheet, no frictional force is generated by the brake disc, and the direct current tubular motor works normally. Several seconds later, power supplied to the brake coil is reduced and the direct current tubular motor can still work normally. When electricity is not supplied to the brake coil, the brake sheet is pushed by the brake spring toward the brake disc, thereby braking the direct current tubular motor. The brake control device is capable of easily meeting requirement of a design, exhibits an appropriate temperature rise, and is high in one-time yield ratio for batch production.
Description
Technical field
The utility model relates to a kind of direct-current tubular motor, especially refers to the braking control device of direct-current tubular motor.
Background technology
Generally being applied in the door and window industry, when load is heavier, can stop reliably to stop in order to make motor, generally use the big more motor model of power, the brake spring elastic force in the brake gear be big more, and the suction that is used for release brake is just big more.And the volume of brake gear is generally all less owing to the restriction of tube shaped electric machine volume, and sealing.In addition, because the brake clearance of this device need be adjusted in the smaller scope when brake strength is little, this spacing is difficult to control when causing production. and the short suction in gap can be smaller, but can not throw off reliably; Gap length can reliablely be thrown off, but suction requires bigger (brake spring strength needs to strengthen).Therefore; Present way all is in design, between the three, to look for a balance point as far as possible in the industry; But because These characteristics; During design or be that brake coil (electromagnet) heating is severe, burn brake brake coil (perhaps require stream time short) brake gear one-pass finished rate was low when brake can not reliably be thrown off or produce easily like this, need adjust repeatedly.
As shown in Figure 1, the brake coil (electromagnet) in the brake gear of prior art is directly parallel in motor brake coil two ends, during machine operation, and the brake coil work of also switching on simultaneously.Three problems of brake gear ubiquity of the direct-current tubular motor of structure like this.1: the brake coil temperature in the brake gear is too high; 2: the brake gear dynamics is soft partially; 3: during batch process, this device one-time success rate is low, needs adjustment repeatedly.
The utility model content
To the weak point that exists in the prior art, the utility model provides a kind of braking control device of direct-current tubular motor.This braking control device ratio is easier to reach designing requirement, the temperature rise appropriateness, and it is high to produce the one-pass finished rate in batches.
For realizing above-mentioned purpose, the utility model technical scheme is:
A kind of braking control device of direct-current tubular motor is characterized in that: this braking control device comprises a brake disc and a brake coil that is fixed in the housing, and a brake spring ejection one brake block activity is being arranged between brake disc and the brake coil; The output shaft of described brake disc connection direct-current tubular motor, described brake coil connects the brake control module, and this brake control module is controlled the electricity condition that gets of brake coil.
The usefulness of technique scheme is:
The utility model braking control device is controlled brake block and brake disc adhesive with throwing off separately.Under the control of brake control module, under brake coil got electricity condition, brake coil produced suction with the past resorption of brake block, and brake disc does not have frictional force, and direct-current tubular motor normally moves; Under brake coil must not electricity condition, brake spring was pushed brake block to brake disc, thereby realized direct-current tubular motor is checked.Thus, adopt total power to supply power, make brake coil produce suction and make brake block and brake disc reliable separation by design load to brake coil in former seconds of work, this moment the device operate as normal, the motor normal operation; Reduce to supply with the power of brake coil then, do not reach the release voltage of brake coil this moment, so brake gear reliable work still, and motor runs well until stopping.But in whole duration of work, the significantly reduction of effective operating current of brake coil (minimum reduce to 30% normal the time) reduces the caloric value of brake coil greatly.Therefore; Can be from designing the operating current of brake coil toward high direction design; So dynamics (can improve the one-pass finished rate of batch process simultaneously) when can guarantee the normal adhesive of brake block and brake disc can reduce the whole work of the brake coil caloric value in period again.

Embodiment
Combine accompanying drawing and embodiment that the utility model is described at present.
The braking control device of a kind of direct-current tubular motor as shown in Figure 2, this braking control device comprise a brake disc (1), a brake block (3), a brake spring (5) and a brake coil (or electromagnet) (4) that is fixed in the housing (6).The output shaft of described brake disc (1) connection direct-current tubular motor, described brake coil (or electromagnet) (4) connects the brake control module, and this brake control module is controlled the electricity condition that gets of brake coil (or electromagnet) (4).Have certain brake clearance (2) between brake disc (1) and the brake coil (or electromagnet) (4), this brake clearance (2) supplies brake spring (5) ejection brake block (3) activity being arranged between brake disc (1) and the brake coil (or electromagnet) (4).
The brake control module is controlled at direct-current tubular motor when stopping, and brake spring (5) is pushed brake block (3) to brake disc (1), thereby realizes direct-current tubular motor is checked; When direct-current tubular motor was worked, brake coil (4) got electric, and brake coil (or electromagnet) (4) produces suction with the past resorption of brake block (3), and brake disc (1) does not have frictional force, and direct-current tubular motor normally moves; After several seconds, the power of supplying with brake coil (or electromagnet) (4) reduces, and direct current machine is operate as normal still, until stopping.
