Abstract:A low-cost two-phases hybrid stepper motor driver is designed. The driver is composed of control circuit based on L297, power drive circuit which consists of discrete transistors and power MOSFETs, and high- frequency switching power supply circuit using SI9114A. The whole system structure is analyzed. The principle and implementation of main circuits are studied. The results of experiment and-use show that the system has the characteristic of single wide-range power supply input, and has good stability and low cost. It may be widely used to small mechano-electronic devices.
Keywords:PWM
