dc.description.abstractThis thesis includes an investigation of the starting capability of a high efficiency synchronous motor for direct on-line industrial applications. The approach is to use a hybrid rotor concept to achieve the starting properties of an induction motor and the steady state performance of a synchronous reluctance motor. The hybrid motor rated at 20 kW is compared and evaluated against a same size induction motor in aspect to parameter variations. Simulations showed that the rotor losses can be reduced by 80 % in the best case. The total motor losses decrease by 20-30 %. This gain in efficiency will improve the efficiency class of the motor from IE3 to IE4. Furthermore, the results from this thesis hopes to raise the interest in investigation of new line-start, high efficiency motors further.
