The paper presents a PWM subdivided driving technigue realized by single chip and field programmable gate array(FPGA) ,following an introduction of stepping motor subdivided control method. Single chips were used to set up the speed and rotation direction,and FPCA was employed to generate step pulse and form a step voltage signal to control voltages at different time produced by each phase winding, thus achieving the free subdivided control of the rotary angle. The PWM module,the speed control module and the digital comparison module of the stepping motor 256 subdivision controllers were realized with VHDL langnage programming.
