A design for the stepping motor controller based on MCU 89C52 and LMD18200 is introduced, which is a 3A H--Bridge de- signed for motion control applications. The motor driver can control the speed and position of the stepping motor accurately. The motor driv- er is consist of MCU （89C52） which is used to control algorithm and real--time calculating, FPGA which is the assistance controller used for peripheral control, H--bridge LMD18200 which is used for motor control, AD converters, RS--422 communication interface. This motor driver is aeronautic--grade and high--reliability. It can be used in aerospace and high--reliability applications.
