A review on linear switched reluctance motor

Abstract

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.

Tubular Linear Switched Reluctance Actuator: Design and Characterization

“…Linear synchronous actuator (LSA) has penetrated the market and established practical applications since hard and soft ferromagnetic material developments. The LSA structure consists of a stator with phase windings powered by the multiphase alternating current (AC) supply similar to a linear induction actuator, while permanent magnet and mover winding with direct-current (DC) supply are located on the mover for constant magnetic flux production to create the electromagnetic poles [1,2]. The permanent magnet's presence caused the LSA to have a sizeable cogging force and normal force in planar LSA [3].…”

Impact of stator slot geometry on the windage loss in a high‐speed linear switched reluctance motor

“…While many motor topologies are applicable for this, the linear switched reluctance motor (LSRM) is more suitable. This is owed to its higher operating speed range, reduced manufacturing cost, and higher faulttolerant capability [3,4]. In contrast to these advantages, force ripple, noise and vibration are major concerns in LSRM technology.…”

Modelagem e Análise da Máquina de Relutância Chaveada com Rotor Externo para Sistema Armazenador de Energia Cinética(Flywheel ) de Alta Velocidade: Modo Motor/Gerador com Controle em Cascata

“…A SRM teve que esperar o desenvolvimento de sistemas de acionamento capazes de satisfazer os seus requisitos de funcionamento, que exige troca de corrente rápida entre as fases e o conhecimento da posição instantânea dos eixos O advento da eletrônica de potência e o rápido desenvolvimento de sistemas microprocessados de alto desempenho e baixo custo, contribuíram sistematicamente para que a SRM se tornasse uma forte candidata para ser utilizada (Chowdhury et al (2017)).…”
