Design and Comparison of a High Force Density Dual-Side Linear Switched Reluctance Motor for Long Rail Propulsion Application With Low Cost

Linear switched reluctance motors (LSRMs) have been an attractive solution for linear driving systems. This paper presents the design and performance comparison of dual side mover and segmental stator LSRM. A conventional teeth-type LSRM, which has identical dimensions, is designed and compared. A design process is developed based on the linear inductance model, and then a standard power equation of this kind of machine is derived, giving a guideline for the design process of the presented LSRM. Using the designed process obtained, a prototype machine is designed and manufactured. Finally, the experimental results from the prototype validate the design procedures and analysis.
