Abstract:Energy storage improvement for electric mobility has become trending topic in I+D, whereas electric machinery performance has been left aside due to its enormous technology advances during the last two decades, even though it has still a wide range of improvement. This thesis investigates the potential of improved performance of a Permanent Magnet Assisted Synchronous Reluctance Motor (PMa-SynRM) considering an unusual material for its lamination. The significant feature of this proposed material is its great mechanical properties which enable rotor lamination designs better suited for high-speed synchronous reluctance motors. However, the material is relatively poor in magnetic capability. Hence, a detailed electromagnetic and mechanical analysis has to be performed to understand the net benefit of employing this material. Three different rotors with same shaft and outside dimensions have been designed to test electromagnetic efficiency and mechanical resistance by the finite-element method. Torque, total reactance, flux density and magnetic field can be evaluated to conclude if this material with its respective modifications provides a better overall performance as well as higher power density to improve electric mobility through electric traction performance.
