“…On the other hand, rated flux control has better transient speed performance compared to the optimal flux control [1], [22]. To overcome the transient speed performance in optimal flux control, a fuzzy logic control (FLC) is employed [19]- [23] instead of the PI controller.…”

The paper presents an accurate loss model based controller of an induction motor to calculate the optimal air gap flux. The model includes copper losses, iron losses, harmonic losses, friction and windage losses, and stray losses. These losses are represented as a function of the air gap flux. By using the calculated optimal air gap flux compared with rated flux for speed sensorless indirect vector controlled induction motor, an improvement in motor efficiency is achieved. The motor speed performance is improved using a fuzzy logic speed controller instead of a PI controller. The fuzzy logic speed controller was simulated using the fuzzy control interface block of MATLAB/SIMULINK program. The control algorithm is experimentally tested within a PC under RTAI-Linux. The simulation and experimental results show the improvement in motor efficiency and speed performance.

The induction motor fulfills admirably the requirements of substantially constant speed drive. This paper presents simulation and development of variable frequency drive by keeping constant voltage-frequency ratio of power supply which is fed to induction motor. A rule-based fuzzy logic controller applied to a scalar closed loop V/f induction motor (IM) speed control,in MATLAB environment. A fuzzy control system uses speed error and speed error variation to change both amplitude and frequency of supplied voltage. Reference speed and load torque variations are also simulated and implemented on hardware.

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. Keywords: induction motor efficiency; motor losses; slitted tooth core design Porast učinkovitosti asinkronih motora pomoću dizajna jezgre s procijepljenim zubomIzvorni zanstveni članak U ovom istraživanju predložen je novi dizajn kako bi se poboljšala učinkovitost rada asinkronih motora. 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.
