Background technology
In textile machine, generally all be provided with a large amount of spindles, and spindle is driven by motor, motor passes through driver drives, the operating voltage of existing driver and drive current are nearly all constant, machine power when starting at the beginning is larger, and generally so large power is not needed after normal work, the driver in actual production made produces waste of energy, if driver therefore can be made to regulate drive current size accordingly according to the change of load, so can reduce the caloric value of driving and motor, thus extend the useful life of driver and motor.
Summary of the invention
Object of the present invention is intended to overcome the larger defect of the driver waste of energy of spindle in existing textile machine, provides a kind of structure simply, convenient to control, the spindle driver electric current automatic regulating system of good energy-conserving effect.
For this reason, the present invention is by the following technical solutions: spindle driver electric current automatic regulating system, it is characterized in that, described automatic regulating system comprises stepping motor, speed measuring device and single-chip microcomputer, stepping motor is provided with motor driver, the rotating speed of stepping motor is controlled by motor driver, described speed measuring device is arranged on the motor shaft of described stepping motor, for monitoring continuously the rotating speed of stepping motor, described motor driver and speed measuring device all carry out data cube computation with described single-chip microcomputer.
As to technique scheme supplement and perfect, the present invention also comprises following technical characteristic.
Described speed measuring device is Hall element or encoder.
Described single-chip microcomputer is connected by MODBUS communication with a controller, can carry out signal export setting to single-chip microcomputer.
Described controller is a computer.
Operation principle of the present invention: single-chip microcomputer output pwm signal also inputs motor driver, make driven MOS field effect transistor, metal-oxide-semiconductor field effect transistor can regulate the electric current of motor driver, at the beginning, metal-oxide-semiconductor field effect transistor regulates the electric current I of motor driver larger, the electric current of motor driver is made to meet the demand of driving stepper motor load, the pulse frequency that now single-chip microcomputer exports is F, the rotating speed of the stepping motor that the electric current I of motor driver is corresponding is V, when after machine operation a period of time, motor driver electric current I is regulated slowly to reduce by single-chip microcomputer to metal-oxide-semiconductor field effect transistor, but the pulse frequency F that single-chip microcomputer exports is constant, when the rotating speed V that speed measuring device monitors stepping motor starts to diminish, stablize to make the rotating speed V of stepping motor, suitably increased by the driver current I of 20% ~ 35% by controller control single chip computer, make driver current I and machine load in practical work process corresponding, make the rotating speed V good stability of stepping motor simultaneously, namely the caloric value of driver and stepping motor is reduced, reach energy-saving effect.
The present invention can reach following beneficial effect: be used for driven MOS field effect transistor by single-chip microcomputer output pwm signal to driver, the electric current of PWM pulse modulation technology to motor driver is adopted to regulate and control, can make machine in course of normal operation, carry out the size of corresponding adjusting driver electric current according to load, reduce the caloric value of driver and stepping motor, reach energy-saving effect, thus extend the useful life of driver and motor.
Accompanying drawing explanation
