This study presents comparative researches on performances of a double‐sided switched reluctance linear machine (DSRLM) under different winding connection modes. The static self/mutual inductances of a 6/4 yokeless DSRLM under two winding connection modes are calculated through the finite element method (FEM). This DSRLM can work either as a motor or as a generator. Now the performances of the DSRLM under different winding connection modes, including the force ripple in the electric model and the output voltage ripple in generation model, are compared through an established electric model and an established generation model. In addition, the iron losses under different winding connections are also investigated. Dynamic magnetic flux density waveforms of the DSRLM are calculated via FEM, and an iron loss computation module is established. Simulation results indicate that the advantages of both winding connections reflect in different aspects. This study summarises how to select a proper winding connection mode of DSRLMs for different performance demands responding to different applications. The experimental validations are conducted on a prototype DSRLM finally.
