The design, optimization and control methods of a transverse flux Linear Switched Reluctance Motor (LSRM) for the rail transit application are introduced. Two structures of LSRMs, EI type and EE type, are compared and analyzed. The structure of EE type machine is optimized from the perspective of average electromagnetic thrust per unit mass through finite element calculations. The initial sizes of the motor are calculated according to the design theory of the rotary SRM. After obtaining the initial sizes, the sensitivities of the LSRM sizes are analyzed by the three-dimensional finite element calculation, and then the sizes such as the slot depth, the slot width and the tooth width of the motor are optimized. The hardware test platform is built, the electromagnetic characteristics of the prototype are tested, and the motor characteristics of the LSRM with different secondary materials are compared. The control method of the LSRM with position sensors is proposed, and then the sensorless control of the motor is also realized based on the pulse injection strategy. The experimental results verify the effectiveness of the design and control strategies.

“…Çapraz akı dağılımına sahip anahtarlamalı relüktans motorları (ÇARM) da içeren çapraz akı dağılımlı makinelerde ise stator ve rotor kutuplarında akı radyal yönlü iken stator ve rotor arka demirlerinde ise eksenel yön söz konusudur. Literatürde yapılan çalışmalarda çapraz akı dağılımına sahip doğrusal ve döner yapıdaki ARM'lerin, KARM'ler ile kıyaslandığında daha yüksek kuvvet/tork ve güç yoğunluklarına sahip olduğu vurgulanmaktadır [8][9][10][11][12][13][14][15]. Aynı zamanda dairesel sargıya sahip ÇARM'lerin bu konuda ciddi avantaja sahip olduğu da belirtilmektedir [16][17][18][19].…”

ÖzYakın zaman içerisinde yapılan çalışmalarda, çapraz akı dağılımına sahip anahtarlamalı relüktans motorların (ÇARM), radyal akı dağılımına sahip klasik anahtarlamalı relüktans motorlar (KARM) ile kıyaslandığında yüksek güç ve tork yoğunluğuna sahip oldukları ifade edilmektedir. Sunulan çalışmada, KARM ile ÇARM'ler arasında kapsamlı bir karşılaştırma yapılmıştır. ÇARM'lerin yapılandırılmasında gereksinim duyulan ek mekaniksel bileşenler, motora ait stator ve rotor bloklarının oluşturulmasında kullanılan malzemeler, ilgili malzemelerin manyetik karakteristikleri ve bu malzemelerin kullanılması sonucu motorun boyutları, hacim ve ağırlığında meydana gelen değişiklikler dikkate alınmak durumundadır. Dairesel sargı konfigürasyonu gibi farklı sargı olasılıkları performans açısından farklılıklar oluşturabilmektedir. Gerçekleştirilen çalışmada, adil bir karşılaştırma yapılabilmesi için KARM ve ÇARM yapıları eşit dış boyut, motor eksenel boyu ve manyetik akı yoğunluğu gibi kriterler ve bunun yanında benzer tork profilleri dikkate alınarak incelenmiştir. İncelenen makinaların performanslarının elde edilebilmesi için analitik hesaplamalar ile birlikte iki ve üç boyutlu sonlu elemanlar metotları (SEM) kullanılmıştır. Çalışmada elde edilen sonuçlar, KARM'lerin ÇARM'ler ile kıyaslandığında aynı ya da daha iyi performans sergilediğini açık bir şekilde göstermektedir. Bununla birlikte KARM'lerin çok daha kolay bir şekilde yapılandırılabilmesi, ilgili motorları ARM yapıları içerisinde avantajlı olan bir yapı olarak ortaya koymaktadır. AbstractHigh power and torque densities have been claimed for transverse flux structures over the conventional (radial flux) switched reluctance machine (CSRM) structures in recent publications. A comprehensive comparison between the transverse SRMs (TSRM) and CSRMs requires inclusion of the specific constructional requirements of the TSRM. Then it must take into account the back irons of the stator and rotor, the material for them and their magnetic characteristics, and their resulting impact on the outer machine dimensions, weight and volume. Performance differentiation that can accrue as a result of different winding possibilities such as hoop (circular) and concentric windings on the TSRM are also considered for the comparison. For a fair comparison of the two types of the SRMs, equal outer dimensions, stack length and magnetic flux density are assumed. In addition, similar torque profiles are also considered. Both analytical and 2D and 3D finite element methods (FEM) are employed in this research to determine the performance of the machines. The research results clearly indicate that CSRMs match or exceed the performance of the TSRMs. In combination with this fact that CSRMs are simpler to construct will make them the choice structure for the switched reluctance motor (SRM) kind.

“…Such approximations lead to error in result. A 3D finite element analysis carried out by ( [5], [39], [14], [15], [26], [6], [49], [19]), provides better accuracy of results with experimental data. Zhang et al [58] has compared the variation in static force as obtained by 2D and 3D FEA for short stack length LSRMs.…”

Summary. Switched reluctance motors have been extensively studied by researchers for their unparalleled advantages in many applications. The linear versions have been developed around the world in the last couple of decades because of attributes similar to that of rotary switched reluctance motor(RSRM). Owing to their frugal design, robust built and high force density, the linear switched reluctance motor (LSRM) has had significant stages of development and optimization. The flexibility in design and operation makes LSRM a prime contender for any linear motor-actuator application. This paper provides a bird's eye view across its developmental stages and its various aspects in design, analysis and control. The following content discusses the salient points of research and the contribution by researchers in this field.
