Experiments in the Position Detection of Linear Switched Reluctance Motor

Position detection is very important in operation of linear switched reluctance motors (LSRMs). With increasing application of LSRMs, the position detection techniques would get more and more attention. In this paper, a position detection scheme is proposed for LSRM. In the scheme, the position is estimated by the injection of a series of small current into phase winding and measurement of the increase of phase current. The preliminary experiments in position detection are performed on the proposed LSRM. The experimental results confirm that the scheme is effective for position detection of LSRM.
