“…24) is used to calculate the mean effect of the ith level of the jth factor on the torque and the torque ripple. For example, to calculate the mean effect of the third level of WB1 factor, among all experiments, the results of third coefficients (3,6,9,12,15,18,21,24,27) are obtained. The same procedure is calculated for the mean effect of the levels of other factors on the target function.…”

“…17 shows the results of the detailed analysis of prototype SynRM. In the application of vehicles, when starting from zero to base speed and to overcome the initial inertial force, the scooter motor must be able to produce its maximum torque (at least two to three times) [12], [31]- [32]. Therefore, the motor needs a high starting current and torque.…”

“…In the third category, the use of multi-objective optimization algorithms for the parametric design of motors with several barriers for optimal design has been performed [10]- [11]. Different methods have been suggested in the literature for rotor design; for example, designing based on magnetic equivalent circuit [12]- [15] mathematical relationships and physical concepts [16] and [17], and most recently, combining these relationships according to sensitivity analysis of the parameters involved [13], [18] and [19]. Rotor design parameters are complicated and timeconsuming.…”

In recent years, synchronous reluctance motor (SynRM) has attracted the attention of researchers and well-known companies have been involved in designing and manufacturing electric motors due to its simplicity. The current study aimed to provide a comprehensive approach to design a series of SynRMs using both combined methods and finite element analysis to achieve an algorithm which is based on the similarity between flux lines and the shape of flux barriers to achieve both maximum torque and minimum torque ripple. In this paper, a SynRM is designed for a specific electric vehicle. Consequently, study cases with a different number of both flux barriers and poles, are analyzed and optimized in each case. Finally, the optimal specifications of the motors are compared in different cases and the best one is selected. Accordingly, the design parameters are identified and optimized through the Taguchi method and then, the obtained results are evaluated through finite element analysis. To achieve both maximum torque and minimum torque ripple in a range of power between 150 to 750 watts, three different number of poles with a constant number of slots (per pole per phase) at the same size for all the described motors are considered. The validity of the proposed method is confirmed through the experimental test results.

“…The authors of [30] employ a combined MEC-FE model for SynRMs which give flux linkages with good accuracy, but it involves two MEC models, namely with d and q-axes networks. Two separate d-q models were created for SynRM in [31] to produce an accurate saliency ratio; however, it is found that, even with two different models of the rotor, predicting a magnetic field in an air-gap is a challenge.

Magnetic Equivalent Circuit Modelling of Synchronous Reluctance Motors

et al. 2022

This paper proposes a modelling technique for Synchronous Reluctance Motors (SynRMs) based on a generalized Magnetic Equivalent Circuit (MEC). The proposed model can be used in the design of any number of stator teeth, rotor poles, and rotor barrier combinations. This technique allows elimination of infeasible machine solutions during the initial machine sizing stage, resulting in a lower cohort of feasible machine solutions that can be further optimized using finite element methods. Therefore, saturation effects, however, are not considered in the modelling. This paper focuses on modelling a generic structure of the SynRM in modular form and is then extended to a full SynRM model. The proposed model can be iteratively used for any symmetrical rotor pole and stator teeth combination. The developed technique is applied to model a 4-pole, 36 slot SynRM as an example, and the implemented model is executed following a time stepping strategy. The motor characteristics such as flux distribution and torque of the developed SynRM model is compared with finite elemental analysis (FEA) simulation results.
