Abstract
The utility model relates to a device for controlling forward and reverse rotation position of a motor, and belongs to the field of motor control technology. The device comprises an AC contactor, travel switches and a button switch; when five elements (namely, a stop button TA, a forward start button QA1, a normally closed contact C2.3 of the AC contactor, a coil C1.1 of the AC contactor, and a normally closed travel switch XW1) are connected in series, two ends of the device are connected with two fuses respectively; and when four elements (namely, a reverse start button QA2, a normally closed contact C1.3 of the AC contactor, a coil C2.1 of the AC contactor, and a normally closed travel switch XW2) are connected in series, one end of the device is connected with to a connection point of the stop button TA and the forward-direction start button QA1, and the other end thereof is connected with a fuse RT2. The device provided by the utility model is simple, safe and reliable, and has the advantages that when equipment is in place, the equipment can stops automatically, the equipment can automatically operate in the reverse direction by pressing the button again, the equipment is accurately in place, and accidents are avoided.
Description
Technical field
The utility model belongs to the Motor Control technical field, particularly a kind of motor rotating control device.
Background technology
Existing is the carrier equipment of the reciprocal operation of power with the motor, after equipment puts in place, stops by Artificial Control, behind the handling goods, again by the Artificial Control inverted running.If operate inaccurately, the equipment off-position is inaccurate, must repeatedly adjust, and control is complicated, also easily causes the accident, and becomes potential safety hazard.
The utility model content
The utility model provides a kind of motor rotating position control, equipment operation is put in place after, automatic stopping, press the inverted running button after, automatic reverse operation again.
The utility model comprises: A.C. contactor, travel switch, push-button switch.The A phase of power supply, C connect the end of fuse RT1, RT2 mutually respectively; After stop button TA, forward start button QA1, A.C. contactor normally-closed contact C2.3, ac contactor coil C1.1, five element connected in series of normally closed travel switch XW1, two ends are connected with the other end of fuse RT1, RT2 respectively; Oppositely after start button QA2, A.C. contactor normally-closed contact C1.3, ac contactor coil C2.1, four element connected in series of normally closed travel switch XW2, an end is connected the tie point of stop button TA and forward start button QA1, another termination fuse RT2; The two ends of A.C. contactor normally opened contact C1.2, C2.2 are connected with the two ends of forward start button QA1, reverse start button QA2 respectively.
The beneficial effects of the utility model are: a kind of simple, safe and reliable motor rotating position control is provided, and energy automatic stopping after equipment puts in place is pressed the operation of button devices automatic reverse once more, puts in place accurately, has prevented the accident generation.

Fig. 2 is the motor main circuit figure that uses the control of the utility model device.
Embodiment
The utility model provides a kind of simple, safe and reliable electric electromechanics motivation rotating position control, and as shown in Figure 1, the utility model comprises: A.C. contactor, travel switch, push-button switch.The A phase of power supply, C connect the end of fuse RT1, RT2 mutually respectively; After stop button TA, forward start button QA1, A.C. contactor normally-closed contact C2.3, ac contactor coil C1.1, five element connected in series of normally closed travel switch XW1, two ends are connected with the other end of fuse RT1, RT2 respectively; Oppositely after start button QA2, A.C. contactor normally-closed contact C1.3, ac contactor coil C2.1, four element connected in series of normally closed travel switch XW2, an end is connected the tie point of stop button TA and forward start button QA1, another termination fuse RT2; The two ends of A.C. contactor normally opened contact C1.2, C2.2 are connected with the two ends of forward start button QA1, reverse start button QA2 respectively.
Fig. 2 is a main circuit diagram of using the control of the utility model device, and three phase mains enters through knife switch DZ, often opens main contacts C1.4 to motor D through A.C. contactor, and energising can make the operation of motor D forward; A.C. contactor often leaves main contacts C2.4 and meets motor D after with the three-phase alternating current commutation, and energising can make motor D inverted running.
During the forward operation, knife switch DZ closes, press forward start button QA1, the A phase current forms the loop through fuse RT1, stop button TA, forward start button QA1, A.C. contactor normally-closed contact C2.3, ac contactor coil C1.1, normally closed travel switch XW1, fuse RT2, the ac contactor coil C1.1 work of switching on, A.C. contactor main contacts C1.4 in the main circuit connects, the operation of motor forward; Simultaneously, A.C. contactor normally opened contact C1.2 connects, and realizes the circuit self-locking, the follow-up reforwarding row of release button; A.C. contactor normally-closed contact C1.3 disconnects, and realizes forward and reverse operation interlocking, prevents to press simultaneously reverse start button QA2, causes the accident.After equipment operation put in place, travel switch XW1 normally-closed contact disconnected, and equipment is out of service automatically.
During inverted running, press reverse start button QA2, the A phase current is through fuse RT1, stop button TA, reverse start button QA2, A.C. contactor normally-closed contact C1.3, ac contactor coil C2.1, normally closed travel switch XW2, fuse RT2 forms the loop, the ac contactor coil C2.1 work of switching on, A.C. contactor main contacts C2.4 in the main circuit connects, the motor inverted running, simultaneously, A.C. contactor normally opened contact C2.2 connects, and realizes the circuit self-locking, the follow-up reforwarding row of release button, A.C. contactor normally-closed contact C2.3 disconnects, realize forward and reverse operation interlocking, prevent to press simultaneously forward start button QA1, cause the accident.After the equipment inverted running put in place, travel switch XW2 normally-closed contact disconnected, and equipment is out of service automatically.Equipment such as need are in operation and stop in emergency, and press stop button TA, and equipment is out of service at once.
Travel switch XW1, XW2 answer the ground of secure fixation at the equipment operation two ends, should be able to reliably trigger open circuit after equipment puts in place.The utility model motor rotating position control is installed in ground fixed position, by cable controlled three-phase alternating current is led on the motor of operational outfit.
