WebSep 10, 2009 · A solid rotor permanent magnet synchronous motor (PMSM) is developed for the electric propulsion part in electric vehicles (EV). The rotor in this kind of motor is composed of splits solid bodies, interior permanent magnets and starting bars. Wedges and bars are shot circuited by end rings that promote the generation of starting torque jointly. … WebPMSM becomes the reference model for MRAS while the current model in the rotor reference frame is set as the adjustable model. The Takagi Sugeno Fuzzy FIS is executed in the MRAS adaptive scheme in order to tune the errors between the reference and adjustable model. ... mechanical loss and stray loss were analyzed to improve the torque equation ...
