As the mine electric locomotive traction motor, it is vital to obtain the permanent magnet synchronous motor rotor position information accurately in the control process. Inject the high frequency voltage signal into motor, the rotor angle and speedestimation was estimated by using Luenberger observer, realized the sensorlessoperation of system, and verified by simulation. The high-frequency pulsating voltage injection method used in the actual mining electric locomotive control system,through field test and subsequent operation proved its accuracy and feasibility.
