Abstract
A novel tubular linear switched reluctance actuator (TLSRA) without permanent magnet that has 7:7 stator-to-mover pole pairs ratio is presented in this paper. A detailed analysis of the effect of mover parameters on the performances of proposed TLSRA is presented to determine the optimized actuator parameters. As comparison, the performances of the conventional TLSRA with 7:5 stator-to-mover pole pairs ratio is also designed and compared with the proposed TLSRA using the identical dimensions. The differences between the proposed and conventional TLSRA is number of available working pole pairs. The proposed TLSRA has four working pole pairs for a three phases actuator instead of two working pole pairs for conventional TLSRA. The additional working pole pairs in the proposed TLSRA exhibit force improvement, approximate two times higher compared to the conventional TLSRA. The static force characteristics for the proposed TLSRA is calculated and computed by using the three-dimensional finite element method (FEM) with ANSYS Maxwell software.
