Conference Record of the 1991 IEEE Industry Applications Society Annual Meeting.
A family of nonintrusive methods is presented for estimating the shaft angle of a switched reluctance machine. Such methods can be utilized for commutation control of the SRM (switched reluctance machine) thereby eliminating the requirement for a sha

A novel switched reluctance motor (SRM) magnetic equivalent circuit model with mutual coupling and multiphase excitation is presented which successfully predicts the magnetic behavior of an SRM with multiple phase at a time excitation. The model is n

An analytical model is presented for linear reluctance motors (LRM) with thin-plate secondaries where the plate is magnetically saturated in normal operation. Finite-element field modeling confirms that the plate has regions of nearly constant magnet

Short-secondary linear reluctance motors (LRMs) have applications in materials handling, particularly for drives through metallic containment barriers. A new theory is given for the normal force in an LRM, taking account of harmonics in the airgap fi
