Description
Technical field
The utility model relates to a kind of folding curtain motor with electromagnet clutch, belongs to motor manufacturing technology field.
Background technology
Folding curtain motor is divided into two classes in the market, exchanges folding curtain motor and direct current folding curtain motor.Exchange folding curtain motor and generally adopt mechanical clutch mechanism, direct current folding curtain motor generally adopts electromagnetic clutch realize while power failure manual folding curtain and chargedly pull automatic startup folding function.
But this two classes motor all exists the defect of self at present, as the problem of temperature rise that exchanges folding curtain motor is the hidden danger being applied on curtain always, and the arrangement of clutch of direct current folding curtain motor, torsion is little, cost height is its bottleneck always, and noise aspect is because the rotating speed of d.c. motor is higher, noise aspect is also large than alternating current machine.
Existing folding curtain motor, generally includes motor, reducing gear and clutch.If motor directly connects folding curtain, because rotating speed is larger, not stretchy folding curtain, therefore need to obtain compared with the slow-speed of revolution, generally can realize by increase planetary gear deceleration device after motor.
Existing mode has and after motor, adds primary planet pinion and add two-stage planet as reducing gear with after motor as two kinds of reducing gears.
Increase the motor of primary speed-down in the time of dead electricity, due to primary planet pinion, speed reducing ratio is little, still can use less power manually to pull curtain adjustment; And the motor that increases double reduction is pulling when operation, due to two-stage planet, speed reducing ratio is large, directly pulls strength at all inadequate, cannot pull motor.
Summary of the invention
The utility model for above-mentioned prior art and deficiency, a kind of folding curtain motor with electromagnet clutch is provided, adopt d.c. motor, after motor, increase two reduction gear, coordinate electromagnet clutch, realize the torsion that powers on large, dead electricity pulls easily.The motor AC and DC improving after design all can be controlled, and can realize power on electric functions and dead electricity manual function.
A kind of folding curtain motor with electromagnet clutch, comprise the reduction box that motor is connected with motor, it is characterized in that described folding curtain motor comprises electromagnet brake, sensing module and control module, separation and the connection between reduction box and motor controlled in electromagnet brake, sensing module monitors motor rotary speed is also transferred to control module by rotary speed information, control module, according to rotary speed information, reaches the control of motor rotary speed by the input voltage of governor motor.
Described reduction box adopts secondary planetary gear to slow down.
After electromagnet brake energising work, reduction box is connected with motor, and motor drives folding curtain normally to work; After electromagnet brake power-off, reduction box separates with motor, and reduction box is not worked.
Reduction gearbox output shaft can, under external force drives, together with the rotation of motor output shaft rotor synchronous, be realized power failure manual function, and the curtain that can drive motor carries out manual folding.
After reduction box is connected with motor, reduction gearbox output shaft can be under the drive of external force, related rotor can together rotate to an angle, by the passive rotation direction of sensing module monitors gear box and motor, thereby judge the direction of the suffered external force of curtain that motor drives, starter motor, can reach and pull function, and curtain carries out folding automatically.
Between motor 1, sensing module 4, control module 5, form closed-loop control, as motor load increases, motor 1 will decline by rotating speed, rotary speed information is passed to control module 5 by signal transducer 4, and control module 5 increases the input voltage of governor motor 1 torque of motor 1, promotes rotating speed, sensing module 4 is monitored again, form like this closed-loop control, reach the variation with load, control motor speed.
The utility model reduction box speed reducing ratio is little, along with the variation of load, control module is constantly adjusted the input voltage of motor according to sensing module institute detection signal, make motor in the situation that being no more than nominal load, and output speed is stabilized in needed setting range always.
Brief description of the drawings
Fig. 1 is the utility model electric machine structure explosive view.
Embodiment
As shown in Figure 1, folding curtain motor comprises the formations such as motor 1, reduction box 2, electromagnet brake 3, sensing module 4, control module 5, power module 6, network interface key-press module 7 and shell.Shell is made up of the first housing 81, the second housing 82 and the 3rd housing 83, and above-mentioned parts are included.
This programme adopts 24V d.c. motor, and deceleration device adopts secondary planetary gear to slow down, and clutch adopts electromagnet braking mechanism.Motor passes through control module, configuration input power exchanges forceful electric power line options, can realize wireless remote control control and exchange heavy-current control motor, motor input line quad, a ground wire G, a zero line N, two live wire L1 and L2, when after L1 and L2 short circuit, passing into after interchange forceful electric power, motor is realized wireless remote control control; Motor forward in the time only meeting L1 and N, in the time only meeting L2 and N, motor reversal, motor is realized heavy-current control; In addition, control board leaves the wiring of 2RJ11 network interface, can realize bus and dry contact control; Deceleration device adopts double reduction, and speed reducing ratio is large, and torsion is large, can drive the curtain (scope of application is more extensive) of heavy load.
Electromagnet brakes after 3 energising work, and reduction box 2 is connected with motor 1, and motor drives folding curtain normally to work; Electromagnet brakes after 3 dead electricity, reduction box 2 separates with motor 1, reduction box 2 is not worked, reduction box 2 output shafts can be under external force drives, together with the rotation of motor output shaft rotor synchronous, can easily pull, the curtain that can drive motor carries out folding control, realize dead electricity manual function, possess the electric functions of powering on and dead electricity manual function simultaneously.
Between motor 1, sensing module 4, control module 5, form closed-loop control, as motor load increases, motor 1 will decline by rotating speed, and rotary speed information is passed to control module 5 by signal transducer 4, and control module 5 is by the input current of governor motor 1, increase the torque of motor 1, promote rotating speed, sensing module 4 is monitored again, forms like this closed-loop control, reach the variation with load, control motor speed.
