摘要
本文提出了一种基于LM629和MC33035的小功率伺服无刷直流电机驱动器设计方案。该方案主要涉及核心控制电路的构成、功率部分驱动电路的设计和整个控制软件的结构。该驱动器通过RS485总线与外界通信,可按照预定参数完成速度和位置伺服。实验证明,该驱动器在驱动18V80W无刷直流电机时有较高的运行精度且稳定可靠。
Based on the integrated circuits LM629 and MC33035, the paper presents a design method of small power servo brushless DC motor （BLDC） driver, and introduces the main control circuit, the driving of power circuits and the structure of software. This driver can communicate externally with RS485 bus and accomplish speed servo and position servo with the scheduled parameters. The experiment shows that the driver provides good stability and precision when driving the 18V 80W brushless DC motor.
