Design and Experimental Verification of Linear Switched Reluctance Motor with Tapered Poles

Linear switched reluctance motors (LSRMs) are considered for numerous applications because of its inherent properties. The force ripple and hence acoustic noise and vibration make this machine failure in compete with the existing linear induction and linear synchronous machines. In this paper a new type of stator structure is proposed and experimented. The proposed structure provides less force ripple and vibration. Parameters like force ripple and vibration are predicted using finite element analysis (FEA). Experimental results are closely correlated with the predicted results.
