Influence of skewing design for reduction of force ripples in DSL-SynRM using 3D FEA

Double Sided Linear Synchronous Reluctance Motors (DSL-SynRM) are being increasingly used in high force density applications. The force ripples are one of the major issue in machine which is due to nonlinear nature of current in the machines. This paper focuses on the reduction of force ripples for increasing the force density of the motor. In order to reduce the force ripples, DSL-SynRM with a skewed translator is proposed. The proposed structure is designed and developed by using computational magnetic tools. This concept is effective for reduction of the force ripples and improves the force density of the machine. The proposed design has been reduced the percentage of force ripples by 21.62 %, improved the force density by 10.32 N/mm³ and efficiency by 0.89%.
