Rotational sensorless control methods which are particular to the railway vehicle applications are presented in this paper. An induction motor speed sensorless control method for railway vehicle traction is introduced, including the re-powering control method. Especially, a mechanical simulator method which is utilized for stating induction motors at zero speed condition are presented. A permanent magnet permanent magnet synchronous motor (PMSM) rotor angle sensorless control method with the induced voltage are also introduced, including harmonics current injection method for starting at zero speed condition. A modified inverter short circuit method for re-powering control method of PMSMs is presented in this paper.
