Abstract
The utility model relates to an electric driven door rolling up machine, which comprises an electromagnetic brake and a single-phase motor, wherein, a suction coil of a DC electromagnet of the electromagnetic brake is connected with a winding of the single-phase motor in series. Due to the adoption of the series connection of the suction coil of the DC electromagnet and the winding of the single-phase motor, the utility model has the advantages of control circuit simplification and cost reduction. Meanwhile, the operating voltage of the DC electromagnet is within 10v, the power consumption of the DC electromagnet is about 10w, and thus, the utility model can ensure that the pressurization of a bridge rectifier can be correspondingly reduced, the temperature rise of the DC electromagnet can be reduced, and the reliability of the electric driven door rolling up machine can be increased.
Description
The utility model relates to a kind of electric roll-up door mechanism, is meant a kind of single-phase electric roll-up door mechanism that is made of electric power control driving mechanism electromagnetic brake and single-phase motor especially.
At present, single-phase electric roll-up door mechanism both domestic and external all adopts the DC electromagnet suction coil connection in parallel with the motor winding.Because electromagnet designs by the short time condition of work, its heat radiation is relatively poor, simultaneously, electromagnet suction coil two ends operating voltage height and the suction coil turn is many, resistance is big, power is bigger, and temperature rise is higher; The alternating current-direct current terminal voltage height of the bridge rectifier of electromagnet causes the withstand voltage of commutation diode to want high, and punch-through often takes place.
The purpose of this utility model is to provide a kind of alternating current-direct current terminal voltage that can reduce the bridge rectifier of DC electromagnet greatly, thereby the electric roll-up door mechanism that reduces the DC electromagnet temperature rise and avoid the bridge rectifier commutation diode to puncture is to overcome above-mentioned defective.
The electric roll-up door mechanism that the utility model proposes is design like this, and it comprises: electromagnetic brake and single-phase motor, the suction coil of the DC electromagnet of its electromagnetic brake and the windings in series of single-phase motor.
Because the utility model adopts the suction coil of DC electromagnet and the connection of motor windings in series, has simplified control circuit, has saved the pair of switches contact in the control circuit, has reduced cost; Simultaneously, the operating voltage of DC electromagnet is in 10V, and power consumption guaranteed the withstand voltage corresponding reduction of its bridge rectifier like this about 10W, and the DC electromagnet temperature rise reduces greatly, has improved the reliability of electric roll-up door mechanism.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the wiring schematic diagram of electric roll-up door mechanism.
Fig. 2 is the structural representation of electric roll-up door mechanism.
Among the figure: 1 be electrical box, 2 for fire prevention blocking device screw, 3 for electromagnetic brake, 4 for the ratchet isolator, 5 for single-phase motor, 6 for gear reduction unit, 7 for curtain axle shaft coupling, 8 for chain, 9 for supporting plate, 10 for the center to center distance adjustment screw, 11 for journey controller, 12 for the chain that goes in ring, 13 for manual operation support, 14 for attaching plug, 15 is press button, M is that single-phase motor, YB are that electromagnet, U are that bridge rectifier, C are capacitor.
With reference to Fig. 2, the electric roll-up door mechanism that present embodiment proposes comprises: electromagnetic brake 3, single-phase motor 5, journey controller 11, gear reduction unit 6 and electrical box 1 etc.With reference to Fig. 1, single-phase motor 5 is a capacitor motor, the starting winding of single-phase motor 5 is connected with capacitor C, connects with single-phase bridge rectifier again with after the operation winding is formed the shunt circuit, and the load of single-phase bridge rectifier is the suction coil of the DC electromagnet of electromagnetic brake 3.
The concrete course of work is: when giving electricity, DC electromagnet and single-phase motor move simultaneously, and electromagnetic brake 3 unclamps, and single-phase motor 5 one shaft extension ends drive the curtain axle by gear reduction unit 6 decelerations, chain 8 transmissions, make curtain door open and close; During dead electricity, electromagnetic brake 3 produces braking rapidly, makes also instantaneous the stopping of single-phase motor 5 after the dead electricity.Can change as required the line footpath size of electromagnet suction coil and the number of turn what, adjust its suction and power consumption, thereby make the voltage distribution between itself and the single-phase motor reach optimum better, satisfy the requirement of electromagnet suction and single-phase motor moment.It can be applicable to the various door lifters of retractable door machine, plate-turning door and rolling door.
