The segmental translator linear switched reluctance motor (STLSRM) is a special type of linear switched reluctance motor (LSRM) that has more output power than its conventional type. Therefore, it can be a good choice for certain applications. Heat is one of the factors limiting the output in machines. Therefore, predicting the thermal distribution of machine is as important as the magnetic design. A comprehensive thermal model is presented based on the lumped parameter approach for STLSRM, which predicts temperature distribution in different parts of this motor, including slot winding, end‐winding, stator pole, stator yoke, and the moving part. Considering that the proposed thermal model depends on dimensions and materials used in machine, it can be used for other designs of the STLSRM. The presented thermal model is applied to a typical STLSRM and temperature is determined in its different parts. The simulation results are then compared with the results of 3‐D thermal modelling based on the finite element method (FEM) for validation.

“…In comparison to the research done on electromagnetic modelling and design of the conventional type of the SRM (onelayer), less attention has been paid to thermal modelling of the onelayer SRM [22][23][24][25][26][27][28][29][30][31][32] and no work has been reported on thermal modelling of the multi-layer SRM. Therefore, it is valuable to develop an accurate lumped thermal model for the multi-layer SRM which is the main objective of the present study.…”

“…The proposed approach couples the finite element (FE) analysis used for propulsion force calculation and the lumped thermal model used for temperature prediction. A novel cooling concept has been presented in [26] for a high‐speed switched reluctance machine used in traction applications. To evaluate the proposed method, a lumped thermal model is developed and the measurements are used to validate the suggested thermal model.…”

The multi‐layer switched reluctance motor (SRM) is a special type of the SRM which can be utilised appropriately in high‐power applications such as electric vehicle (EV). Thermal modelling of the multi‐layer SRM is considered for the first time in the present study and a lumped parameter thermal model is introduced for quick prediction of temperature rise in this motor. In the introduced lumped thermal model, independent thermal networks are considered for different parts of the machine including frame, stator yoke, stator pole, winding, air‐gap, end‐winding, end‐cap air, rotor pole, rotor core and shaft. All details of the modelling and the required equations are given and therefore someone can use the model easily. The developed thermal model is applied to a typical two‐layer 8/6 SRM and a prototyped three‐layer 8/8 SRM and the simulation results are then compared with those derived from three‐dimensional finite element (FE) method using ANSYS FE package and experimental results. These comparisons show well high computation speed and accuracy of the lumped thermal model developed for the multi‐layer SRM.

To investigate the influence of control and structure parameters on the starting performance of a switched reluctance motor, a 12/8 pole switched reluctance motor is analyzed in this paper. The novel field-circuit coupled finite element method of switched reluctance motor is proposed in the paper. The influence of the controller on the switched reluctance motor is considered. The influence of rotor initial position angle, starting mode, starting current, and structure parameters on the starting performance of the switched reluctance motor is studied using the field-circuit coupled finite element method. The starting performance of the switched reluctance motor is obtained under the different control and structure parameters. The alternating starting mode of single- and two-phase winding can improve the starting torque of switched reluctance motor (SRM). As the stator pole arc coefficient increases, the starting torque of SRM increases. The appropriate reduction of the air gap length can improve the starting torque of SRM. Experimental results of the prototype are compared with the calculation results, which verifies the reliability of the calculation method and accuracy of the calculation results.
