基于单片机的电机变频起动方法

Starting Mode of Motor with Variable Frequency Based on Single Chip Microcomputer

提出一种以80C196KC+DSP为控制核心的交-交变频控制方法,实现电动机重载起动方案。该方法具有起动电流小、起动转矩大、起动平滑、运行稳定、控制效果好的特点。对系统主电路、控制部分系统软件等进行了详尽论述,对试验及仿真结果进行了分析。

To resolve the disadvantages of motor loading starting, the 80C196KC ＋ DSP style AC/AC variable frequency was introduced . It has many virtues such as small start current, stable start process, good running, etc. Its main circuit connection and control system was discussed specify. The experiment and simulation results were analyzed.
