Jd. Law et al., MAGNETIC-CIRCUIT MODELING OF THE FIELD REGULATED RELUCTANCE MACHINE .1. MODEL DEVELOPMENT, IEEE transactions on energy conversion, 11(1), 1996, pp. 49-55
A transient magnetic circuit model of a field regulated reluctance mac
hine is presented. The model is based on flux loop equations rather th
an node equations as have previously been employed. A key feature of t
his approach is that magnetic circuit models based on loop equations p
ermit an entire machine to be represented by only one equivalent pole.
