Abstract Among high speed data chips，TMS320F240 is most suitable for SPWM control. It is able to control six of the switching components to realize SPWM
frequency conversion regulating. The basic structure and features of the ship，and the principle of SPWM frequency conversion regulation，as well as the main
inverting circuit of the motrized spindle are introduced briefly in this paper. Through experiments and practical operation，it is proved that TMS320F240 is powerful
and features high speed operation，it is suitable for controlling 3 phase AC motors.
