“…Optimization of the induction motors advances further with the usage of fuzzy logic based controller acting as a supervisor in reducing flux levels during the transients and contributes to the efficiency improving of the dynamic operating modes [12]. Maximization of the efficiency at the induction motors is achieved by introducing mechanical improvement in stator and rotor core, i.e., slits in the middle of the stator and the rotor teeth [13,14]. This paper sets the comprehensive parametric analysis regarding efficiency improvement of permanently split capacitor motor and gives an overview of how the parameters are changed in optimized models in comparison to the starting model.…”

Single-phase motors are known for their small power ratings and their usage in various household appliances. Although they are not large electricity consumers, their widespread application contributes to the overall electricity consumption. In addition, standard IEC 60034-30-1:214 defines the efficiency levels for single- and three-phase motors and stipulates the increased electrical efficiency for the electrical motors. Therefore, this paper sets the parametric analysis of permanently split capacitor motor with five different design parameters that have impact on the efficiency of the motor. As an output from the parametric analysis, two different optimized motor models are obtained with increased efficiency. The impact of each parameter on motor efficiency—as well as on the other operating characteristics, like starting torque, overloading capacity, rated current, starting current, total losses, and power factor—is analyzed and adequate conclusions are derived. The obtained motor models are verified with Finite Element Method (FEM) for magnetic flux density distribution.

“…Optimum slit value was determined as 15.00 mm. At the end of the modeling, 1.869% improvement was obtained in the motor models that had 15.00 mm slit depth and 0.10 mm slit width compared with the efficiency values of reference model at rated operation point [30]. Aho and friends examined the electromagnetic torque change by adding slits to solid rotor induction motor rotor structure in their study.…”

In this study, a new design was suggested in order to improve the performance of induction motors. In these new designs, slits were applied in the middle of stator and rotor tooth parts. In these slitted models, the depth and width of slits were optimized by Finite Element Method Magnetics (FEMM) by using Finite Elements Method (FEM). Starting torque, pull-out torque, rated torque and torque-speed characteristics of the new motor model formed with the proposed slitted construction and reference motor model are given in comparison. The motor model is made with 56 slits which have different depth and width to see the effects of slits in the stator and rotor. In modeling, 3 kW squirrel-cage induction motor was used. As a result of modeling, increase in the coupling flux provided 2.085% and 4% increase especially in pull-out and rated torque values respectively.

Original scientific paper In this study, a new design was suggested in order to improve the performance of induction motors. In the proposed design, slits were applied in the middle of stator and rotor teeth. In these slitted models, the depth and width of slits were optimized with Finite Element Method Magnetics (FEMM) software using Finite Elements Method (FEM). To show performance improvement, suggested motor model and a reference motor model were compared at the rated operating point for the values such as input and output power, input current, power factor, efficiency and losses. Because of the decreases in both iron and copper losses, total losses in motor were reduced and the efficiency for rated operating point was improved by 1,869%. In the modelling, 3 kW squirrel-cage induction motor was used.

U predloženom dizajnu primjenjeni su procijepi u sredini zubi statora i rotora. U ovim procijepljenim modelima dubina i širina procijepa su optimizirani uz pomoć programa Magnetska metoda konačnih elemenata (FEMM) i koristeći Metodu konačnih elemenata (FEM). Za prikaz poboljšanja izvedbe, predloženi model motora i referentni model motora su uspoređeni u definiranim pogonskim tačkama za vrijednosti kao što su ulazna i izlazna snaga, ulazna struja, faktor snage, efikasnost i gubitci. Zbog smanjenja gubitaka željeza i bakra, ukupni gubitak u motoru je smanjen, a povećana je efikasnost za definiranu pogonsku tačku za 1,869%. U modeliranju korišten je 3 kW kavezni asinkroni motor.
