“…When a 3-phase IM is symmetrical in the EM structure, its single-phase equivalent circuit can be used to describe the 3phase system. In order to describe the EM phenomenon of IM, the excitation branch with parallel structure should be used for analysing the relationship between the magnetising current and core loss current [21][22][23]. The T-type equivalent circuit model of 3-phase IM shown in Figure 1 is thus used in this study.…”

“…In the research, it is found that the excitation current is given in proportion to time, which will cause flux unsaturated and aggravate the torque fluctuation. Based on the above ideas, i 1ds takes the constant value i * 1ds and i 2ds takes the constant value i * 2ds , the excitation current mathematic formula is showed as (8). From two pairs poles to one pair poles mode, the torque current switching mathematical formula is showed as (9), the mathematical formula of excitation current is still (8).…”

“…[1][2][3][4][5]. For example, in the electric vehicle driving system, it is required to provide large torque at low speed and a wide speed range, and the MIM can meet the requirements by using the pole-changing strategy, which is both efficient and convenient [6][7][8]. Therefore, it has been extensively studied.…”

“…However, it is time-consuming, which is not desired when a fast performance evaluation of a motor is required in the industry. The analytical methods presented in literature are based on the following: magnetic potential-permeance [2][7]- [13], vector superposition [14] [15], subdomain models [4][16]- [19], winding functions [1][5] [20] and magnetic equivalent circuit [21]- [23]. The magnetic potential-permeance method is widely used, in which the slotting effect can be calculated by the permeance function [7]- [13].…”

“…Therefore, it can only calculate the radial component of the magnetic field, but not the tangential. In order to make the calculation more accurate, either the finite element method needs to be combined [21] or the magnetic circuit needs to be divided more finely [22][23], which will increase the number of magnetic circuit nodes and make the calculation model more complex. In [1], the equivalent air gap function is used to calculate the AR-MF considering inhomogeneous saturation of the core.…”
