| Abstract: | Micro-stepping driving control system for chopping wave constant current of electromagnetic motors is mainly composed of AT89C51 microcomputer, resonant circuit, address latch unit, decoder, EEPROM memory, and programmable keyboard/display control (Intel-8279) etc. Micro-stepping current control signal from microcomputer is converted into analog voltage signal through D/A converter. After the analog signal is compared with sampling signal, chopping wave control signal is formed to control the conduct/cut of pre-stage driving control circuit. Close-loop control of winding current and precise micro stepping is realized with this way. |
