Abstract
The utility model discloses a clockwise and anticlockwise rotation controller which is used for preventing false activation of a motor, comprising a clockwise rotation starting button switch, an anticlockwise rotation button switch, a clockwise and anticlockwise rotation assistant button switch, a stop button switch, a first contactor and a second contactor. When the clockwise rotation starting button switch and the clockwise and anticlockwise rotation assistant button switch are pressed at the same time, the first contactor is electrified to close and self-locked; the main contact is closed; and the motor rotates clockwise; when the anticlockwise rotation starting button switch and the clockwise and anticlockwise rotation assistant button switch are pressed at the same time, the second contactor is electrified to close and self-locked; the main contact is closed; and the motor rotates anticlockwise. The clockwise and anticlockwise rotation controller disclosed by the utility model can effectively prevent the false activation of a motor; if any one button is mis-pressed at ordinary times, the false activation of the motor can be avoided, so that the clockwise and anticlockwise rotation controller is applicable for manufacturing machines at complex construction occasions.
Description
Technical field
The utility model relates to a kind of control device of electric motor, relates in particular to a kind of positive and negative rotating controller that is used to prevent the motor error starting.
Background technology
In each processing industry, using motor is absolutely necessary; Tend to because misoperation, mistake are bumped switch, cause situation such as damage machine, have an accident, the error starting motor is a kind of breakneck operation; Particularly when machine is detected; The error starting motor just is in peril of one's life probably, so general control device security performance is very poor.
Summary of the invention
The purpose of the utility model provides a kind of positive and negative rotating controller that is used to prevent the motor error starting with regard to being in order to address the above problem.
The utility model is realized above-mentioned purpose through following technical scheme:
The utility model comprises just changes start button switch, counter-rotating start button switch, rotating assistant starting push-button switch, stop button switch, first contactor and second contactor; Said just changeing after the series connection of start button switch and said rotating assistant starting push-button switch two ends be first shunt circuit after the normal open switch of said first contactor is parallelly connected; Said counter-rotating start button switch and two ends after said rotating assistant starting push-button switch is connected be second shunt circuit after the normal open switch of said second contactor is parallelly connected; One end of AC power is connected with an end of said first contactor and an end of said second contactor simultaneously; The other end of said first contactor is connected in series with the normally closed switch of said second contactor, said first shunt circuit and said stop button switch successively; The other end of said stop button switch is connected with the other end of said AC power; The other end of said second contactor is connected in series with the normally closed switch and said second shunt circuit of said first contactor successively, and the other end of said second shunt circuit is connected with the public connecting end of said first push-button switch and said first shunt circuit; Said AC power also is connected in series with the thermal relay break contact.
The beneficial effect of the utility model is:
The utility model can effectively prevent the error starting of motor; If bump any one button at ordinary times by mistake; Can not cause the error starting of motor, and not know hints on operation, can not make motor start-up at all yet; Therefore this device also has encryption character, applicable to some manufacturing machine of complicated construction occasion comparatively.
Description of drawings
Accompanying drawing 1 is the circuit structure schematic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing: the utility model comprises just changes start button switch S B2, counter-rotating start button switch S B3, rotating assistant starting push-button switch SB4, stop button switch S B1, the first contactor KM1 and the second contactor KM2; Just changeing after start button switch S B1 and the rotating assistant starting push-button switch SB4 series connection two ends be first shunt circuit after the normal open switch of the first contactor KM1 is parallelly connected; Counter-rotating start button switch S B3 and two ends after rotating assistant starting push-button switch SB4 connects be second shunt circuit after the normal open switch of the second contactor KM2 is parallelly connected; One end of AC power is connected with the end of the first contactor KM1 and the end of the second contactor KM2 simultaneously; The other end of the first contactor KM1 is connected in series with normally closed switch, first shunt circuit and the stop button switch S B1 of the second contactor KM2 successively; The other end of stop button switch S B1 is connected with the other end of AC power; The other end of the second contactor KM2 is connected in series with the normally closed switch and second shunt circuit of the first contactor KM1 successively, and the other end of second shunt circuit is connected with the public connecting end of the first push-button switch SB1 and first shunt circuit; AC power also is connected in series with thermal relay break contact FR.
Shown in accompanying drawing: the utility model is a rotating control device that prevents error starting, compares with typical positive and reverse rotation control circuit, has increased a rotating assistant starting button SB4, thereby needs with the hands operation.
Shown in accompanying drawing: when just changeing start-up control, the right hand is pressed just changes start button switch S B2, and left hand is pressed rotating assistant starting push-button switch SB4, just can make contactor KM1 get electric adhesive and self-locking, and its main contacts is closed, and motor just changes.
Shown in accompanying drawing: during the counter-rotating start-up control, the right hand is pressed counter-rotating start button switch S B3, and left hand is pressed rotating assistant starting push-button switch SB4, just can make contactor KM2 get electric adhesive and self-locking, and its main contacts is closed, the motor counter-rotating.
Shown in accompanying drawing: when stopping to control, press stop button SB1, cut off the control circuit power supply, the motor stall.
Because actuating motor must be pressed two buttons simultaneously, if bump any one button at ordinary times by mistake, can not cause the error starting of motor, and not know hints on operation, also can not make motor start-up at all.Therefore this circuit also has encryption character, applicable to some manufacturing machine than the complicated construction occasion.
