Abstract
The utility model provides a kind of bottle blowing machine motor-drive circuit；Embryo motor M2, upper embryo transmission translator M1 are pulled including frequency converter, upper embryo runner motor M3, upper embryo, the frequency converter, upper embryo runner motor M3, upper embryo are pulled embryo motor M2, power supply L and power supply N-port and are connect respectively with the zero line side N of power supply and zero line L, the end of the ground connection of frequency converter is grounded, the X1 and COM port of frequency converter and the analog output end of PLC connect, the voltage output end of the three-phase of frequency converter is connect with upper embryo transmission translator M1, is connected with switch K1 between the port S1 and SC of frequency converter.The utility model strengthens protector defencive function; keep protection scope wider; to motor occur turn-to-turn short circuit negative-sequence current it is smaller and protect controller do not have defencive function in terms of obtain good improvement; pass through PLC and Frequency Converter Control; making motor operation is not in conflict, and embryo material caused by electrode failure is avoided to fall.
Description
Technical field
The utility model relates to a kind of bottle blowing machine motor-drive circuits.
Background technique
Medical sodium chloride is blown on flat machine, it usually needs includes brshless DC motor and three-phase in motor to a motor feeding
Alternating current generator, original motor control model are each individually control, are not cooperateed between motor, and when feeding embryo material usually occurs and falls
Phenomenon, and circuit does not have a defencive function, motor is easily damaged when line fault.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of bottle blowing machine motor-drive circuit.
The utility model is achieved by the following technical programs.
A kind of bottle blowing machine motor-drive circuit provided by the utility model；Including frequency converter, upper embryo runner motor M3, upper embryo
Embryo motor M2, upper embryo transmission translator M1 are pulled, the frequency converter, upper embryo runner motor M3, upper embryo pull embryo motor M2, power supply L
It is connect respectively with the zero line side N of power supply and zero line L with power supply N-port, the end ground connection of the ground connection of frequency converter, the X1 of frequency converter
It is connected with the analog output end of COM port and PLC, the voltage output end of the three-phase of frequency converter and upper embryo transmission translator M1 connect
It connects, is connected with switch K1 between the port S1 and SC of frequency converter.
The power supply line that the upper embryo runner motor M3, upper embryo pull embryo motor M2 also decomposes two masters of cut-in relay KM
Contact, the output switch parameter end connection of relay KM and PLC.
It is direct current generator that the upper embryo runner motor M3, upper embryo, which pull embryo motor M2,.
The upper embryo runner motor M3, upper embryo pulls the zero line side of embryo motor M2 and ground terminal passes through capacity earth.
Power circuit protector CP4 is also connected on the zero line L of the power supply.
The utility model has the beneficial effects that: strengthening protector defencive function, keep protection scope wider, to motor
Generation turn-to-turn short circuit negative-sequence current is smaller and protects controller not have defencive function aspect and obtains good improvement, pass through PLC
And Frequency Converter Control, making motor operation is not in conflict, and embryo material caused by electrode failure is avoided to fall.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
A kind of bottle blowing machine motor-drive circuit；Embryo motor M2, upper embryo are pulled including frequency converter, upper embryo runner motor M3, upper embryo
