摘　　要：介绍了一种高精度高可靠步进电机驱动控制系统的设计。该设计充分利用TMC260智能驱动芯片的优势,结合FPGA自由编程特点,设计了两相步进电机驱动电路。电路实现了电机在宽频内256细分的高精度步进,并具有电机过载检测、堵转报警等功能,作为血液分析仪的核心驱动部件在临床应用取得了很好的效果。A design on stepping motor drive control system with high precision and high reliability is introduced in the paper. Making full use of intelligent driver chip TMC260, and combining with freely programmable FPGA features, a drive circuit of two phase stepping motor is designed based on this method. The drive circuit realizes the motor step with 256 segments in the broad- band high precision, and achieves functions of motor overload and stall alarm. As a core drive part of blood analyzer, the method has a good effect on clinical application.
