The article designs a variable frequency system for asynchronous motor based on LPC2138. It uses SPWM and constant ratio of voltage to frequency algorithm, and selects high-performed LPC2138 as the central control unit. As the system adopts digital control, it achieves high precision control and high treatment speed. Its structure is simple and the system is highly stable. The practice indicates that the system can adjust the speed smoothly and the device switching loss is few, and can be used for various industrial applications.
