Design Method of High-grade Synchronous Motor Spindle Drive Circuit Using Domestic Chips
This paper mainly expounded the design of three closed-loop digital AC synchronous electric spin-dles composed of all localization chips.Using pre-processing data storage,adopted the method of prepro-cessing data storage.Low-end chips and new methods were used,so that ordinary domestic chip could also achieve high-speed chips with imported comparable to achieve high-performance digital AC servo control.The shortage of imported chips has been solved in China's spindle industry.The hardware structure and im-plementation method adopted by the control system were introduced.
