Motor-driven is the basic driver form of pipelining, as the product of raw-material conveying, tinuous production or semi-finished product conveying etc.Because need long-term operation when motor and the work of attached drive apparatus, if fault, then whole production line Awaiting Overhaul such as need stop work influences ordinary production.Therefore, for this situation operated by rotary motion two cover driving arrangements, promptly two motors and two cover drive apparatus can start standby driving arrangement after wherein a cover driving arrangement breaks down, and what guarantee to produce normally carries out.

In the prior art, the control circuit of two cover driving arrangements is relatively independent, simultaneously, for the high-power driving motor, control circuit comparatively complicated (such as adopting soft initiator or Frequency Converter Control); The probability that control circuit breaks down is bigger, if the control circuit fault another set of drive apparatus mechanical operating part fault or the motor of a cover driving arrangement damage, then two cover driving arrangements all can not use, and then pipelining can't move, and what influence was produced normally carries out; Particularly behind the cover driving arrangement long-term operation, the control circuit of stand-by equipment does not start for a long time, is easier to break down, and causes the appearance of above problem.

Thereby, need improve existing driving arrangement control circuit, can guarantee that at least one cover driving arrangement can run well, thereby the production unit that guarantees pipelining can produce continuously by long period, enhance productivity, save production cost.

The utility model content

In view of this, utility model provides a kind of motor output control circuit, can guarantee that at least one cover driving arrangement can run well, thus the production unit that guarantees pipelining can produce continuously by long period, enhance productivity, save production cost.

The motor output control circuit of utility model, comprise the control circuit Q1 of motor M 1 and the control circuit Q2 of motor M 2, be connected in series switch QF1 and switch QF3 on the described control circuit Q1 successively, be connected in series switch QF2 and switch QF4 on the control circuit Q2 successively, the output contact leading-out terminal of described switch QF1 and the output contact leading-out terminal of switch QF2 are electrically connected.

Further, described control circuit Q1 output also in parallel connects pays line loop Q1 ', control circuit Q2 output also in parallel connects pays line loop Q2 ', pay line loop Q1 ' and be connected in series switch QF5 and switch QF7 successively, pay line loop Q2 ' and be connected in series switch QF6 and switch QF8 successively, the output contact leading-out terminal of described switch QF5 and the output contact leading-out terminal of switch QF6 are electrically connected;

Further, be electrically connected by switch QF9 between the output contact leading-out terminal of the output contact leading-out terminal of described switch QF7 and switch QF8;

Further, described switch QF5, switch QF7, switch QF6, switch QF8 and switch QF9 all are the chain control switch by control circuit Q1 and control circuit Q2 control.

Further, described control circuit Q1 is the soft initiator output circuit, and control circuit Q2 is the frequency converter output circuit.

The beneficial effect of utility model: the motor output control circuit of utility model, adopt the interoperable control circuit structure of two cover driving arrangements, at a cover drive apparatus control circuit of another set of driving arrangement when breaking down simultaneously machinery or electrical fault appears and, can guarantee that still a cover driving arrangement can run well, thereby the production unit that guarantees pipelining can be produced by long period continuously, enhance productivity, save production cost.
