Description
Technical field
The present invention relates to electrical equipment manufacturing technology field；A kind of control circuit applying to motor braking.
Background technology
Motor is indispensable parts in commercial production, and a lot of equipment will lean on driven by motor could run, very
Many occasions need motor to brake rapidly, and present motor braking method is a lot, and such as electromagnetic brake is exactly a kind of conventional motor
Braking method, and for some motors needing Fraquent start, braking, braking can make mechanical braking contracting equipment life frequently
It is short, so that the production cost of enterprise increases.
Summary of the invention
It is an object of the invention to provide a kind of direct current energy consumption control for brake circuit, it can solve Fraquent start, braking
Motor uses the problem that mechanical braking cost is high.
In order to solve the problems referred to above, the technical solution used in the present invention is: this direct current energy consumption control for brake circuit, including
Stop button and start button, described stop button, start button and the series connection of the first catalyst form the first catalyst and control electricity
Road, described start button formation in parallel with the first catalyst holding circuit, described first contactor control circuit and braking circuit
Series connection, described braking circuit includes that rectification module, the outfan of described rectification module are connected in series with described first catalyst
Normally-closed contact, relay and the normally opened contact of the first catalyst, the normally-closed contact of described first catalyst and the series connection of relay
Circuit is in parallel with electric capacity, and the outfan of described rectification module also one end with the normally opened contact of the second catalyst is connected, and described
The other end of the normally opened contact of two catalysts is connected with motor stator, and described relay and the series connection of the second catalyst form second and connect
Tentaculum control circuit.
In technique scheme, more specifically scheme is it may also is that described relay is coil resistance is the height of 3 kilo-ohms
Sensitive relay.
Further: on described first contactor control circuit, be also associated with fuse.
Further: described stop button, the first catalyst and display lamp series connection form motor and run indicating circuit.
Owing to have employed technique scheme, the present invention compared with prior art, has the beneficial effect that due to this
Bright employing rectification module, relay and capacitor are braked, and are a kind of electric brakings, do not have mechanical braking, so to frequency
Numerous starting, the motor of braking will not increase the cost of enterprise because of mechanical braking shortened equipment life.
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:
Direct current energy consumption control for brake circuit shown in Fig. 1, including stop button SB1 and start button SB2, stop button SB1, opens
Dynamic button SB2 and the first catalyst KM1 series connection forms the first contactor control circuit, start button SB2 and the first catalyst KM1
Parallel connection forms holding circuit, and the first contactor control circuit is connected with braking circuit, and braking circuit includes rectifier module D, rectification
The outfan of module D is connected in series with the normally opened of the normally-closed contact of the first catalyst KM1, relay K A and the first catalyst KM1
Contact, the normally-closed contact of the first catalyst KM1 and the series circuit of relay K A are in parallel with electric capacity C, the outfan of rectifier module D
Also one end with the normally opened contact of the second catalyst KM2 is connected, and the other end of the normally opened contact of the second catalyst KM2 is fixed with motor
Son connects, and relay K A and the second catalyst KM2 series connection form the second contactor control circuit；On first contactor control circuit
It is also associated with fuse FU；Stop button SB1, the first catalyst KM1 and display lamp RD series connection form motor and run indicating circuit.
During work, circuit breaker Q F of closing, press start button SB2, the first contactor control circuit obtains electric, electric motor starting,
Now, the normally-closed contact of the first catalyst KM1 in braking circuit disconnects, the normally opened contact Guan Bi of the first catalyst KM1, electric capacity
C is electrically charged；When wanting motor stalling, press stop button SB1, the first contactor control circuit dead electricity, in braking circuit
The normally-closed contact Guan Bi of one catalyst KM1, the normally opened contact of the first catalyst KM1 disconnects, and electric capacity C is 3 kilo-ohms to coil resistance
High sensitive relay KA electric discharge, make the adhesive of relay K A, the second contactor control circuit obtain electric, thus carry out direct current energy consumption system
Dynamic；After certain time, electric capacity C discharge off, relay K A discharges, the second contactor control circuit dead electricity, end of braking.Electricity
The capacity holding C determines braking time length, and the breakdown reverse voltage of rectifier module D requires that, more than 500 volts, electric current holds according to motor
The size of amount selects.
