Description
Technical field
The utility model relates to direct current machine switch operation circuit, is specifically related to a kind of control circuit being applied in the larger driving direct current machine traffic direction of power.
Background technology
Because DC MOTOR CONTROL is simple, not very high or the relatively simple occasion of run action uses direct current machine to be than better suited in some technical requirement.
Although the integrated function ratio of the various control IC of current manufacturer production is comparatively comprehensive, in the occasion that drive current demand is larger, due to the Power Limitation of IC itself, the lower situation that direct current machine will be caused to drive of output current.
Such as when door closure drive motors snap close frictional force is larger, the operating current of drive motors can increase, and IC now exports and cannot meet the demands, and motor is run not, or applies electric current by force and cause that IC is overheated to be burnt.
Utility model content
The purpose of this utility model is to provide a kind of circuit that can realize the corresponding direct current machine switch operation larger for power compared with the motor commutation operation under large driving force conditions of demand.
For solving the problems of the technologies described above, the utility model is used for the circuit of the larger direct current machine switch operation of power, and comprising: motor commutation control device R, motor M is connected with described motor commutation control device R; IGBT power control switch Q1, described IGBT power control switch Q1 is connected with described motor commutation control device R by source electrode; Second source VCC2, described second source VCC2 are connected with the drain electrode of described IGBT power control switch Q1; The collector electrode of triode Q2, described triode Q2 is connected with the coil of described motor commutation control device R, the grounded emitter of described triode Q2; First power supply VCC1, described first power supply VCC1 is connected with the coil of described motor commutation control device R.
Described motor commutation control device is dpdt relay.
The utility model is used for the circuit of the larger direct current machine switch operation of power after the IGBT using relatively high power and dpdt relay, by applying extra drive singal, can realize corresponding to the motor commutation operation under large driving force conditions of demand.
Accompanying drawing explanation
Fig. 1 is the utility model for the electrical block diagram of the larger direct current machine switch operation of power.
Embodiment
Below in conjunction with accompanying drawing, the circuit that the utility model is used for the larger direct current machine switch operation of power is described in further detail.
As shown in Figure 1, the utility model is used for the circuit of the larger direct current machine switch operation of power, when dpdt relay R is in certain state, the both positive and negative polarity of motor M is by the drain electrode access motor drive power supply VCC2 of IGBT (insulated gate bipolar transistor) power control switch Q1, and now motor runs towards certain fixing direction.When needs commutate, Q1 first closes by control signal D1, motor is out of service, triode Q2 is driven to make dpdt relay R action by control signal D2 again, make motor M be linked in circuit according to the direction contrary with both positive and negative polarity before, after power control switch Q1 is opened by control signal D1, VCC2 is by place in circuit, motor M obtains a reverse drive current, realizes the inverted running of motor.
The utility model is used for the circuit of the larger direct current machine switch operation of power after the IGBT using relatively high power and dpdt relay, by applying extra drive singal, can realize corresponding to the motor commutation operation under large driving force conditions of demand.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
