  Abstract
  the paper has built a Double Three Phases Permanent Magnet Synchronous (DTP-PMSM) mathematic model. There are two kinds of analysis methods for DTP-PMSM Direct Torque Control theory research.£¨1£©the flux linkage produced by the two set of windings may be researched on as a whole, the Direct Torque Control(DTC) theory is similar to the three phrases PMSM¡££¨2£©the flux linkage produced by each set of winding may be researched on independently, the function relation can be obtained between the torque and its angle. In simulation experiment, the relative characteristic has been researched on one or both set of windings of the DTP-PMSM. The simulation results show that two kinds of method may be feasible, and the motor running manner may be selective in term of application occasion. The research has built a better theory and application basis for the DTP-PMSM control system.
