Abstract

This paper presents the design and optimization of tubular Linear Switched Reluctance Actuator (LSRA) without permanent magnet that has 12:8 stator-to-mover pole pairs ratio. The performances between 6:4 and 12:8 stator-to-mover pole pairs ratio tubular LSRA are compares in term of the generated thrust force. At the same excitation current, the generated thrust force of tubular LSRA with 12:8 stator-to-mover pole pairs ratio found to be more than three times as that of 6:4 stator-to-mover pole pairs tubular LSRA. In order to obtain the optimum performance of the proposed tubular LSRA, the design optimization and the influence of tooth width and mover tooth height on generated thrust force are analyzed and computed using commercial 3D Finite Element Method (FEM) analysis software (Maxwell 3D Version 17.0). The results shows that the proposed actuator with optimized design parameters generates the maximum output thrust force for approximately 2.05 N when 3 A excitation current is applied.
