“…It is possible to create the desired design by using an approximation method and a computer software working parallel with the finite difference and finite element methods. By applying a FEM to machine design, it is possible to determine the electromagnetic parameters at a very high accuracy in that manner [29][30][31]. Finite element analysis was developed to find approximate numerical solutions of the magnitudes that are continuous in a particular region such as the fields and their variations on the studied region.…”

Çalışmada, 2,5 kW gücünde 14 kutuplu, 84 oluklu sabit mıknatıslı senkron generatörün (SMSG) analitik tasarımı, analizi ve optimizasyonu gerçekleştirilmiştir. Bu tasarıma ait verim, tork, vuruntu torku ve manyetik akı yoğunluğu gibi performans özelikleri değerlendirilmiştir. Ardından mıknatıs geometrisinin vuruntu torkuna etkisini incelemek amacıyla ilgili generatörün 3 boyutlu modeli çıkartılmıştır. Bu bağlamda bölünmüş ve kaykı/çarpıklık (skew) verilmiş mıknatıs yapılarının etkileri araştırılmıştır. İlk tasarımda mıknatıs tek parça modellenmiş ve vuruntu torkunun etkin değeri 436,75 mNm olarak bulunmuştur. İkinci tasarımda mıknatıs yüzeyi boyunca belli ölçüde çarpık bir yarık açılmış ve bu işlem vuruntu torkunu 434,58 mNm değerine düşürmüştür. Diğer tasarımda, birinci tasarımdaki mıknatıs iki parçaya bölünmüş ve bölünen mıknatıslar çarpık şekilde tekrar birleştirilmişlerdir. Böylece vuruntu torkunun değeri 159,60 mNm olarak bulunmuştur. Son olarak, son modeldeki mıknatıs geometrisine belli ölçülerde iki tane yarık açılarak vuruntu torku 89,95 mNm'e kadar düşürülmüştür. Elde edilen sonuçlardan, son tasarımın, ilk tasarıma kıyasla vuruntu torku değerinde %80'e varan bir iyileşme sağladığı sonucuna varılmıştır.

Summary An air gap optimization study of a 3‐kW axial flux three‐phase permanent magnet generator has been performed. The machine has two rotors sandwiching a stator with 12 separated laminated cores under an innovative flux morphology circulating over the back‐iron components. The rotor component has 16 rare earth magnets with an innovative self‐cooling blade structure. According to the air gap parametric magnetostatic analyses under the finite element method (FEM) between the range of 0.8 and 7 mm, the spatial magnetic flux distribution and cogging torque values have been determined. Besides, following the magnetostatic analyses, time‐dependent FEM simulations over the generated voltage and power values have been studied in detail. Then, after the implementation of the designed machine, the experiments have been performed for various air gap values. The generated power is observed to be dependent on the air gap, the efficiency is measured as 85%, and power density is measured as 111.7 kW/m3, which is a promising value compared to the literature. A scaling effect study is performed as functions of air gap and rotor speed for the first time to our knowledge. The maximum cogging torque is measured as 3.12 Nm. The other superiority of the present prototype is its low total harmonic distortion value within 2%; thereby, it generates nearly an ideal sinusoidal waveform. Consequently, the novel machine is recommended for both off‐grid and on‐grid operations with its low harmonic distortion and high efficiency.

“…These machines can be used in industry as motor and compensator, energy generation as generator (Hansen & Michalke 2008;Adlya & Huzayyin 2019;Bayındır & Vadi 2017). Particularly because of their high efficiency, there is increasing interest in synchronous machines (Bouloukza et al 2018). SynRM is consider as one of the synchronous machine types has no magnetic parts or any winding in the rotor construction.…”

In recent years, the variable speed motor drive is supported over a fixed speed motor drive as per essentialness safeguarding, speed or position control and improvement of transient response characteristics. The aim of any speed controller is to take main signal that represent the reference speed and to drive the framework at that reference speed. This paper exhibits the design, simulation and control of synchronous reluctance motor (SynRM). In addition, the motor speed is controlled by utilizing a conventional PID controller that has been used from the cascaded structure. The Particle Swarm Optimization (PSO) was used to find the best parameters of the PID controller. Lead-Lag controller presents from the cascaded controller as the following period of control. The Space vector pulse width modulation (SVPWM) plot has been proposed to control the motor and make the motor work with no rotor confine contingent upon the info parameters that utilization in the simulation. An examination between both of PID tuned and PSO tuned controller affirms that the PSO gives dazzling control highlights to the motor speed and have an edge over the physically changing controller. Thus, this paper present investigation and simulation for the most precise procedures to control the speed reaction and torque reaction of synchronous reluctance motor (SynRM).©2020. CBIORE-IJRED.
