Abstract:An asynchronous motor has a simple structure and is reliable in operation and easy to maintain. Along with the de原
velopment of electronic devices,microprocessors and control techniques,AC speed adjustment is more and more widely ap原
plicable. The paper introduces the research and discussions on the variable-frequency speed control system for AC asyn原
chronous motors and proposes corresponding hardware and software designs. Control chip DSP TMS320LF2407A for TI motors
together with SVPWM control methods were used to regulate the speed of AC induction motors with a variable frequency,thus
greatly improving the running accuracy of AC motors.
