Modeling of a saturated switched reluctance motor using an operating point analysis and the unsaturated torque equation

This paper describes torque production in a saturated switched reluctance motor (SRM). The paper begins by deriving the equations for torque if the SRM is unsaturated. It then develops an operating point model for torque in a saturated SRM using the unsaturated form of the torque equation. This results in a methodology which makes the control algorithms applicable to either saturated or unsaturated SRMs
