Today, with the decrease in fossil fuel reserves, interest in electric vehicles has grown. Undoubtedly, electric machines are one of the most important parts of electric vehicles. Studies on electrical machines directly affect vehicle performance. Since the electrical machine used is mounted on the vehicle, reducing the total weight without changing the output power will positively affect the overall performance of the vehicle. The windings used to create the magnetic field in electrical machines are made of copper. Electrical machinery manufacturers try to use completely different materials instead of copper or partially reduce its use. At this point, aluminum emerges as an attractive material for various manufacturers. This study analyzed the winding structure of a switched reluctance machine (SRM) proposed for an electric vehicle by using copper and aluminum at an equivalent resistance value, the results of which were compared. As a result of a 2D finite element analysis, it was observed that the machine’s output performance is largely kept when aluminum is used instead of copper for the winding. It was also observed that the aluminum total winding weight decreased by 43,40% compared to that of copper.

We present a new internal gear transmission based on spatial involute-helix curve in this article. Firstly, the generation principle of spatial involute-helix curve is proposed according to gear geometry theory. Mathematical design model of the spatial conjugate involute-helix curves is provided through establishing the meshing relationship solved by relative velocity and specific normal vector at contact point. The equations of conjugated spatial involute-helix curve and line of action of contact curves are derived, respectively. Secondly, tooth profiles construction with spatial involute-helix curve pair is carried out by isometric offsetting and kinematics methods. General tooth profiles form and numerical example are proposed in terms of given design parameters. Furtherly, meshing analysis of generated tooth profiles are discussed. Center distance separability and axial errors action are discussed according to the theoretical derivation and simulation process. Contact stress analysis and the comparison are studied by finite element method. Finally, the experimental test of the new gear pair manufactured by CNC technology is provided and general transmission efficiency results and contact conditions of tooth profiles under different error conditions are displayed. Research conclusions show that the new internal gear drive has well transmission property and further study on the contact dynamic and error analysis will be carried out.

“…This paper presents the design procedure of 8\6\8 DSAFSRM with a multilevel air gap and pole shoe to mitigate the torque ripple. Slot fill factor (S.F.F) is taken as 0.43 [30][31][32] and average current density taken as 12 A/sq mm. As our both stators at the outer stator are exposed to environment this could be the permissible limit for thermal consideration.…”

High torque and power generation capability of double-stator axial flux switched reluctance motor (DSAFSRM) makes it superior to conventional and segmented rotor switched reluctance motors. Despite its significant feature, the ripple in developed torque still limits the usefulness of DSAFSRM for widespread industrial application. This paper proposes an 8/6/8 pole DSAFSRM with modification in rotor pole shape to reduce torque ripples in respective model. The respective phase windings of the upper and lower stators are excited externally by preparing the circuit in Maxwell software. Each rotor tooth is constructed with two types of slots with different levels of air gap to change the inductance profile. Firstly, the design of a conventional DSAFSRM has been presented; thereafter, some geometric modifications in the rotor tooth have been suggested and investigated to obtain a lower torque ripple at 1200 rpm in the proposed DSAFSRM. The efficacy of the proposed motor is investigated through finite element method (FEM) based analysis and also by comparative analysis with other types of switched reluctance motors. It can be inferred from the simulation results that the torque ripple is significantly reduced by 55.62% in the proposed DSAFSRM compared to the conventional DSAFSRM. However, the efficiency of the proposed DSAFSRM (73.87%) is slightly less than the conventional DSAFSRM (74.65%).
