Abstract: To fulfill the request of large speed scale,big torque,high stabilization,the drive system of high performance spindle based on TMS320F2812 was designed which included hardware and software.In addition the theory of FOC(Field Orientated Control)and the calculation of flux were introduced.According to the theories,the drive system of spindle was built and a detailed debug process and some of the experiments were given.The results of  the experiments prove that the system has excellent static and dynamic performances.
