| Abstract: | A solution to control a permanent magnet synchronous motor(PMSM) of sensorless using the TMS320LF2407 is discussed.A brief introduction of the mathematic model and the vector control of PMSM is presented,and the method of ascertaining the rotor position under the circumstance of speed sensorless is also mentioned.The control method of i_d=0 on salient pole PMSM which is sensorless is put forward,which shows that if we use the digital signal processor we can make the complicated vector control arithmetic come true easily,and can also resolve the coupling characteristic of motor effectively. |

| Keywords: | PMSM sensorless field orientated vector control digital signal processor |
