Description

Direct current energy consumption brake control

Technical field

The present invention relates to electrical equipment manufacturing technology field；A kind of control device 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 brake control, 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 brake control, including Control chamber, is provided with the first catalyst and the second catalyst, the chamber door of described control chamber is provided with in the case of described control chamber 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, in the case of described control chamber, it is also equipped with rectification mould Block, electric capacity and relay, described first contactor control circuit connects with braking circuit, and described braking circuit includes described rectification Module, the outfan of described rectification module is connected in series with the normally-closed contact of described first catalyst, relay and the first contact The normally opened contact of device, the normally-closed contact of described first catalyst and the series circuit of relay are in parallel with electric capacity, described rectification mould The outfan of block also one end with the normally opened contact of the second catalyst is connected, the other end of the normally opened contact of described second catalyst Being connected with motor stator, described relay and the series connection of the second catalyst form the second contactor 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: be also equipped with fuse in the case of described control chamber, described first contactor control circuit also connects It is connected to fuse.

Further: on the chamber door of described control chamber, to be also equipped with display lamp, described stop button, the first catalyst and instruction Lamp series connection forms motor and runs 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 front view of the control chamber of the present invention.

Fig. 2 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 brake control shown in Fig. 1 and Fig. 2, including control chamber, be provided with in the case of control chamber circuit breaker Q F, First catalyst KM1, the second catalyst KM2, rectifier module D, electric capacity C, fuse FU and relay K A, the case of described control chamber Stop button SB1, start button SB2 and display lamp RD, stop button SB1, start button SB2 and the first contact are installed on Men Device KM1 series connection forms the first contactor control circuit, start button SB2 and the first catalyst KM1 parallel connection and forms holding circuit, the One contactor control circuit is connected with braking circuit, and braking circuit includes rectifier module D, and the outfan series connection of rectifier module D is even It is connected to the normally-closed contact of the first catalyst KM1, relay K A and the normally opened contact of the first catalyst KM1, the first catalyst KM1's The series circuit of normally-closed contact and relay K A is in parallel with electric capacity C, and the outfan of rectifier module D is also with the second catalyst KM2's One end of normally opened contact connects, and the other end of the normally opened contact of the second catalyst KM2 is connected with motor stator, relay K A and the Two catalyst KM2 series connection form the second contactor control circuit；Fuse FU it is also associated with on first contactor control circuit；Stop Only 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.
