    Recently with the development of power switching device and DSP which has peripheral devices to control AC servo system, the servo technology has met a new development opportunity. Those things make it possible to reduce the time of developing a AC servo system. However these DSP are all fixed point DSP such as TMS320F240, TMS320F2407, TMS320F2812 and so on. This is a disadvantage of calculating floating number so TMS320C32 or TMS320C31 which are floating point DSP have been implemented to AC servo system so far. It increases the cost and causes the complex hardware. In this study, a DSP based AC servo system with a 3-phase PMSM is proposed. The newly produced DSP TMX320F2812-version C which has the performance of fast speed, 150MIPS, and rich peripheral interface such as 12bit high speed AD converter, QEP(Quadrature Encoder Pulse) circuit, PDPINT(Power Drive Protect Interrupt), SVPWM module and dead time module is used. This paper presents a method to overcome fixed point calculating using scaling all parameters. Also space vector pulse width modulation (SVPWM) using off-set voltage and the digital PI control are implemented to the servo system. However, there are two things to improve developed AC servo system. The first one is compensating dead time effects and the other one is current prediction. In addition, TMX320F2812 which is a experimental version has some trouble with ADC module at high speed conversion. TMS320F2812 which is regular product should be substituted for TMX320F2812 to the AC servo system. In conclusion, the AC servo system is developed and experimented. If the suggestions above are performed, developed AC servo system would be a high performance torque control system and have a strong economical advantage .
