“…The analysis of SRM of two different stator geometries keeping rotor parameters constant is presented [1] from the result analysis, the variation of inductance, flux density and directional force along X, Y axis of both the model have been predicted. This study can be used to get more improved performance and to manufacture SR with further modification of physical size of motor [2]. Discussed about the comparison of three phase induction motors with two different stator slot shapes of same ratings.…”

Switched Reluctance motors are very demanding among all type of motor due to its simple construction. Feedback circuit (control circuit) and design of Switched Reluctance Motor (SRM) require information of its parameters, like inductance, flux linkage and torque. High torque, high reliability and cheap manufacturing cost are the attractive features of the SR motors. In this paper we have simulated SR motor with initial design, teethed stator pole and multi-teethed stator pole using COMSOL multi-physics CAD software. We have plotted inductance profile and static torque characteristics which shows that the static torque characteristics has peak value with sharp reduction in torque in intermediate position with teethed stator pole, that can be overcome by using multi-teeth stator pole with compromising in maximum torque.

Currently, the eco-friendly vehicle market is growing continuously. In the automobile industry, various electric vehicle models are being developed, and several technological innovations are being made. Certain limited vehicle types, such as passenger cars, are being converted to electric vehicles; moreover, a variety of small electric vehicles, including smart mobility vehicles, are being developed. The driving motor of an electric vehicle, e.g., a brushless Direct Current motor (BLDC), is one of the key components that determine its driving performance. However, since the recent hike in prices of the rare earth magnets used in BLDCs, the development of induction motor with lower cost and a simple product structure has become essential. Therefore, this study proposes an optimized design for an outer rotor induction motor with high efficiency in the low-speed section for electric vehicles. The motor designed in this study is efficient for speeds less than 1000 rpm, and our experimental results prove that the prototypes can provide up to 84.8% efficiency. This optimized motor is expected to have widespread application in the eco-friendly vehicle market.

“…Sundaram and Navaneethan analyzed the motor performance using new slot geometry in an underwater induction motor. They stated that the magnetization current can decrease, and the efficiency value can increase by 5% with the new stator geometry they suggested [4]. Boglietti and friends outlined how the electromagnetic design of a three-phase induction motor is effectuated [5].…”

In this study, a new design was suggested in order to improve the performance of induction motors. In these new designs, slits were applied in the middle of stator and rotor tooth parts. In these slitted models, the depth and width of slits were optimized by Finite Element Method Magnetics (FEMM) by using Finite Elements Method (FEM). Starting torque, pull-out torque, rated torque and torque-speed characteristics of the new motor model formed with the proposed slitted construction and reference motor model are given in comparison. The motor model is made with 56 slits which have different depth and width to see the effects of slits in the stator and rotor. In modeling, 3 kW squirrel-cage induction motor was used. As a result of modeling, increase in the coupling flux provided 2.085% and 4% increase especially in pull-out and rated torque values respectively.
