“…Electrical equivalent circuit of the stator part is given during modelling, whereas the mechanical part is given in the form of differential equations. Electrical equivalent circuits belonging to permanent magnet synchronous machines (Kazerooni et al , 2013; Lee and Hur, 2017; Lee and Hur, 2019; Zhang et al , 2018; Dehkordi et al , 2005), brushless DC motors (BLDCs) (Ishikawa et al , 2013; Liu et al , 2014; Xia et al , 2020), IMs (Ge et al , 2022) and synchronous reluctance machines (Li et al , 2023; Sangwongwanich, 2020) are generally built considering stator part. Therefore, the electrical equivalent circuit is actually missing in the models made for both DC and AC machines.…”
