Description
Technical field
The present invention relates to electrical equipment manufacturing technology field；A kind of control line for DC motor positive and negative rotation
Road.
Background technology
Motor is indispensable parts in commercial production, and a lot of equipment will lean on driven by motor to run, right
In requiring frequently to carry out the direct current generator of rotating operation, change turning of motor frequently with the mode changing armature supply direction
To, but it is when producing main overvoltage that this mode exists a kind of defect, is easily damaged motor.
Summary of the invention
It is an object of the invention to provide a kind of DC motor positive and negative rotation and control circuit, it can solve when producing overvoltage
Time, the problem being easily damaged motor.
In order to solve the problems referred to above, the technical solution used in the present invention is: this DC motor positive and negative rotation controls circuit, bag
Include stop button, rotate forward start button and reversion start button, described stop button, rotate forward start button, reversion catalyst and
Positive contactor series connection is formed and rotates forward contactor control circuit, formation in parallel with the positive contactor self-insurance of described rotating forward start button
Circuit, described stop button, reversion start button, positive contactor and reversion catalyst series connection form reversion catalyst and control electricity
Road, described reversion start button and reversion catalyst formation in parallel holding circuit, described positive contactor is connected with motor formation
Motor prograde circuit, described reversion catalyst is connected with motor and is formed motor reversal circuit；Described positive contactor and reversion connect
Tentaculum is connected with motor field winding respectively and is formed field winding control circuit, and described motor field winding is in parallel with discharge resistance
Form motor protective circuit.
In technique scheme, more specifically scheme is it may also is that described positive contactor is connected with red led
Forming motor and rotate forward indicating circuit, described reversion catalyst is connected with green indicating lamp and is formed motor reversal indicating circuit.
Owing to have employed technique scheme, the present invention compared with prior art, has the beneficial effect that due to this
Bright being provided with discharge resistance, when producing overvoltage, discharge resistance can carry out dividing potential drop, thus protect motor to damage.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the present invention.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
DC motor positive and negative rotation shown in Fig. 1 controls circuit, including stop button SB1, rotates forward start button SB2 and reversion startup
Button SB3, stop button SB1, rotating forward start button SB2, reversion catalyst FKM and positive contactor ZKM series connection form rotating forward
Contactor control circuit, rotates forward start button SB2 formation in parallel with positive contactor ZKM holding circuit, stop button SB1, instead
Turning start button SB3, positive contactor ZKM and reversion catalyst FKM series connection and form reversion contactor control circuit, reversion starts
Button SB3 and reversion catalyst FKM formation in parallel holding circuit, the main contact of positive contactor ZKM is connected with motor M and is formed electricity
Machine prograde circuit, the main contact of reversion catalyst FKM is connected with motor M and is formed motor reversal circuit；Positive contactor ZKM is with anti-
Contactor FKM connects with motor field winding L respectively and forms field winding control circuit, motor field winding L and electric discharge electricity
Resistance Rf parallel connection forms motor protective circuit.Positive contactor ZKM and red led HR connects and forms motor rotating forward indicating circuit,
Reversion catalyst FKM and green indicating lamp HG connects and forms motor reversal indicating circuit.
When wanting motor to rotate forward, pressing rotating forward start button SB2, rotate forward contactor control circuit and obtain electric, motor rotates forward electricity
The main contact Guan Bi of the positive contactor ZKM in road, motor M rotates forward；When wanting motor to stop, pressing stop button SB1, rotate forward
Contactor control circuit dead electricity, the main contact of the positive contactor ZKM in motor prograde circuit disconnects, and motor M rotates stopping；When
When wanting motor reversal, pressing reversion start button SB3, reversion contactor control circuit obtains electric, the reversion in motor reversal circuit
The main contact Guan Bi of catalyst FKM, motor M inverts, and when wanting motor to stop, pressing stop button SB1, and reversion catalyst controls
Circuit dead electricity, the main contact of the reversion catalyst FKM in motor reversal circuit disconnects, and motor M rotates stopping；Owing to motor is excitatory
Winding L is in parallel with discharge resistance Rf, and when producing overvoltage in circuit, overvoltage can be discharged by discharge resistance Rf, be kept away
Exempt from the damage of motor.
