Abstract: For special scenarios, permanent magnet synchronous motor was necessary to track the speed to drive it to work properly. For the special working condition, a method of calculating the speed and angle of the PMSM based on shortcircuit current method was introduced, and the feasibility and accuracy of the scheme through theoretical analysis and simulation analysis were verified.

Key words: permanent magnet synchronous motor, short circuit current method, rotor angle
