Abstract
Based on the structural characteristics and magnetic flux distribution of the segmented bilateral LSRM (Linear Switched Reluctance Motor), a magnetic network model of the motor under single-side excitation is constructed using the magnetic circuit segmentation method in this paper. The influence of the lateral displacement of the motor mover on the winding inductance is analyzed. On the basis of the coupled voltage method for estimating mover position, the relationships between the coupled voltages and the positions of the motor in both directions under asymmetric air gaps are further studied, and a position detection index that can avoid the influence of uneven air gaps is proposed. Finally, on the laboratory prototype test platform, sensorless control experiments are completed for the motor without lateral displacement of the mover and under different lateral displacement conditions. The experimental results show that the LSRM position sensorless control method based on the coupled voltages of both coils proposed in this paper can achieve accurate estimation of the starting position, smooth starting operation, and chopping control velocity regulation operation under different lateral offsets of the motor.

期刊介绍:
IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest.
IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on:
Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals.
Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering.
Development of new or improved fabrication or manufacturing techniques.
Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
