Investigation on magnetic saturation in switched reluctance motor using 2D hybrid finite element method

This paper investigates the magnetic saturation in switched reluctance motor. A two-dimensional hybrid finite element method is used to describe magnetic behaviors, energy conversion loops and electromagnetic torque generated for non-saturated and saturated motors, respectively. The analysis shows that magnetic saturation in motor benefits the output capability just under certain constraints. In some cases, the non-saturated motor can produce more torque than that of the saturated motor. In whatever the nonsaturated or saturated motor, high maximum nonsaturated inductance L_au is recommended, which is beneficial to output torque produced
