Abstract
In this letter, based on a structural decoupling design for the mover, a bearingless linear switched reluctance motor is proposed to simplify the levitation force control. This mover is designed to exhibit two decoupling features, one feature is that the levitation field and the armature field is decoupled by separating the levitation part and the armature part using the modular design with an E‐core structure. The other feature is the self‐inductance of the levitation module is decoupled from the mover position in the X‐direction by specially designed size of the levitation module. Based on this simple and decoupled mover structure, the levitation force can be controlled linearly by adjusting the magnitude of the levitation current without the information of the armature current and the mover position in the X‐direction, that is, the levitation current control is a simple scalar control, and the levitation force control and the thrust force control are structurally decoupled. Based on the FEA results, the design and theoretical analysis are verified. © 2018 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
