Description
Technical field
The utility model belongs to motor device, is specifically related to a kind of flybar motor based on PLC control.
Background technology
At present, the control hardware of known motor positive and inverse is the coil through button or knob-operated conducting A.C. contactor mostly, makes the coil of A.C. contactor produce magnetic force adhesive major loop motor power, realizes the control to the rotating of motor.The configuration of this control is because of after the influence of mechanical life of receiving hardware uses a period of time generally speaking, the performance rather unstable, and can't realize digital control.
Summary of the invention
The purpose of the utility model is to provide a kind of flybar motor based on PLC control, is a kind of based on the EPA The Application of Technology, and is to realize rotating and reverse of motor, simple in structure, easy to operate through the PLC control technology, and stable performance is safe and reliable.
For achieving the above object; A kind of flybar motor of the utility model based on PLC control; Comprise motor, electrical power control cabinet, PLC and the intelligent touch-screen that is connected through signal wire with PLC, said motor is connected with the signal input part of PLC through control line through scrambler, and the control end output signal of PLC is connected with frequency converter through signal control line; Frequency converter links to each other with motor through power lead, by the forward or reverse of PLC control motor; Said electrical power control cabinet is connected with the power input of PLC through power lead; Said and PLC are connected with limit sensors through signal control line, and limit sensors is fixedly mounted on the flybar motor, transmit signal by the operation of PLC control motor or stop through limit sensors.
Said electrical power control cabinet comprises isolating switch, phase shortage detecting unit and electric motor protecting unit.
Said motor is a variable-frequency motor.
In technique scheme, after the operator sent starter motor, PLC powered on just for the coil of the contactor of motor, machine operation, and the motor forward or reverse is notified PLC control automatically after designing requirement.If selected machine operation behind limit position, is just sent a signal to PLC, after PLC receives this signal, cut off motor, motor quits work.Frequency converter is used in the driving of motor; With the code device signal of motor after computing; Voltage by controller output is certain is given frequency converter, the speed and the position of control motor, and frequency conversion is slowed down automatically when starting and stopping soon; Well alleviate the phenomenon of overshoot, this closed loop constitutes accuracy and the stability that improves the operation of flybar motor.The technical scheme of the utility model, simple in structure, be easy to operate through intelligent touch-screen, and stable performance, safe and reliable.
Description of drawings
Fig. 1 is connection side's block diagram of a kind of flybar motor based on PLC control of the utility model.
Embodiment
Below in conjunction with accompanying drawing a kind of flybar motor based on PLC control of the utility model is done further explain.
Visible by Fig. 1, a kind of flybar motor based on PLC control of present embodiment is a kind of based on the EPA The Application of Technology, and main mode of operation is that screen window substitutes the conventional button operation.Present embodiment comprises motor, electrical power control cabinet, PLC and the intelligent touch-screen that is connected through signal wire with PLC; Motor is connected with the signal input part of PLC through control line through scrambler; The control end output signal of PLC is connected with frequency converter through signal control line; Frequency converter links to each other with motor through power lead, by the forward or reverse of PLC control motor; In the present embodiment, electrical power control cabinet comprises isolating switch, phase shortage detecting unit and electric motor protecting unit, and electrical power control cabinet is connected with the power input of PLC through power lead; Be connected with limit sensors with PLC through signal control line, limit sensors is fixedly mounted on the flybar motor, transmits signal by the operation of motor on the PLC opertaing device or stop through limit sensors.
In the present embodiment; PLC is that the quantity of controlled motor is as required come type selecting, and controlled motor can be selected small PLC for use below 5, and controlled motor 5-15 platform can be selected Medium PLC for use; Controlled motor can be selected Large PLC for use more than 15, also can many PLC combinations use.
Adopt the technical scheme of the utility model, after the operator sent starter motor, PLC powered on just for the coil of the contactor of motor, machine operation, and equipment operation is notified PLC control automatically after designing requirement.If selected flybar machine operation behind limit position, is just sent a signal to PLC, after PLC receives this signal, cut off motor, motor quits work.Frequency converter is used in the driving of motor; With the code device signal of motor after computing; Voltage by controller output is certain is given frequency converter, the speed and the position of control motor, and frequency conversion is slowed down automatically when starting and stopping soon; Well alleviate the phenomenon of overshoot, this closed loop constitutes accuracy and the stability that improves the operation of flybar motor.In addition, present embodiment adopts frequency converter to realize the position control function, is the application example in the present domestic flybar controlling Design, and it operates steadily, the parking atremia, and bearing accuracy can reach ± 3mm.
