“…In previous studies, rotor slot areas were mostly kept constant to compare the effect of different rotor slot geometries over the performance of the motors [7,11,27,28]. However, in studies analysing and optimising the effect of single rotor slot shape, rotor slot area is mentioned to be highly effective on the performance of a CRIM [9,13,29].…”

Although the performance of an Induction Motor (IM) can be maximized for any speed by use of an inverter, there is still room to contribute by optimizing the rotor slot shape while decreasing the mechanical disturbing effects and acoustic noise. This paper focuses on the effect of different individual rotor slot shapes on the performance of an IM including overall space harmonic, vibration and acoustic effects. A number of rotor slot shapes were implemented to the rotor of a commercial IM and efficiency of all designs were maximized for constant torque region by optimization. Afterwards, operational performance including starting, breakdown and rated operations; moreover, harmonic content and torque ripple were analyzed numerically in association with the mentioned rotor slot shapes. Best performing 4 rotor slot shapes in terms of chosen operational quantities were designated. Furthermore, the determined motors were carried out to vibration and acoustic noise analysis. Superposed acoustic disturbances in terms of sound power level for different harmonic frequencies were obtained and results are given in comparison. All-inall, this paper contributes to associating the end-to-end disturbing effects to certain rotor slot shapes. This study determines disturbance and performance criterions for choosing an appropriate motor for an IM to be used in an electric vehicle. It was shown that rotor slot shape still deserves considerable attention to increase the performance of an IM while decreasing the adverse effects of space harmonics, mechanical vibration and acoustic disturbance.

S ingle phase induction motors (SPIMs) nowadays are widely used in domestic and commercial areas because of cheap cost, simple structure, low noise and small dimensions etc. Split phase, start and run-capacitor single phase induction motors are well known SPIM motor types [1]. Although a lot of advantages have mentioned, a SPIM has some disadvantages. Its efficiency is low and starting performance is not so good to compare the other electrical machines types.The optimal design of an induction motor in terms of electromagnetic torque means starting and breakdown torques are higher value [2]. Many researchers have investigated to improve the starting torque and efficiency of a SPIM. Some of them have focused the influence of rotor slot geometry like rotor slot type, shape, skewing, number of rotor slot, slot opening and core material.Zhou Rui et al [3], have modeled two single phase induction motors with Maxwell 2D software and changed their dimensions in Maxwell 2D to find optimal slot geometry with respect to starting performance and efficiency. In similar studies; S. Sobhani et al [4] have examined dimensions of two SPIMs and mechanical

“…Bunlar yüksek kalkış momenti ve yüksek devrilme momentleridir. Bu momentler ise rotor oyuk geometrisine doğrudan bağımlıdır [4][5][6]. Oluk yapılarının farklılığı, motorun kalkış, devrilme ve nominal işletmesindeki rotor direnç ve endüktans değer-lerini, dolayısıyla moment değerlerini değiştirmektedir.…”

Bu çalışmada asenkron motorlarda optimal rotor oluk ölçülerinin, Sequential Nonlineer Programming (SNP), Genetik Algoritma (GA) ve Sequential Mixed Integer NonLinear Programming (SMINP) yöntemleri ile bulunması gerçekleştirilmiş ve karşılaştırmalı olarak motor performansına olan etkisi incelenmiştir. Gerçekleştirilen optimizasyon çalışmasındaki amaç maksimum motor veriminin sağlandığı oluk geometrisini elde etmektir. Simülasyon çalışmaları, Ansys Maxwell paket programı kullanılarak gerçekleştirilmiştir. Gerçekleştirilen optimizasyon çalışması sonrasında elde edilen rotor oluk geometrisine göre Ansys Maxwell 2D programında motor modeli oluşturulmuş ve gerekli analizler gerçekleştirilmiştir. Elde edilen sonuçlara göre, en verimli motor geometrisi GA algoritması kullanıldığında elde edilmektedir..
