Title :
A Kind of Design of Step Motor Constant Torque Chopper Driver
Abstract :
The paper introduced the drive scheme and realizes the technique of step motor constant torque and chopper based on control of AT89C52 single chip microcomputer, By selecting reasonably division electric current waveform of each phase winding for step motor, and ensure the resultant magnetic field amplitude is constant, and realize the step motor constant torque, improve the resolution of subdivision driving. The operating result indicates the drive system that has been designed its division precision is high and operating is smooth, noise and power loss is low and reliability is great and the property price rate is high.
