“…Due to the extremely low raw material cost, ferrite PM is a feasible solution for reducing the cost of EV. Given the shortcomings of relatively low energy density and coercivity, many new techniques related to motor topology are proposed, among which three kinds of topologies are employed, namely the spoke type PM motor, axial flux PM motor, and PMassisted synchronous reluctance motor [30][31][32][33][34][35][36][37].…”

“…The PMasyRM improves the reluctance torque by optimizing the design of rotor barriers, segments, and ribs, which can partially compensate for the decrease in torque performance caused by the reduction in the rare earth PM. Therefore, this topology is suitable for combining with ferrite PM as a low-cost solution with a small sacrifice in torque performance [33,34,[36][37][38]. FIGURE 1 and FIGURE 2 show the structure of conventional synchronous reluctance motors without PM and PMasynRM motors, respectively [34,39].…”

“…One of the most common cooling methods for electric motor applications is the use of cooling jackets, in which a coolant absorbs the heat flux generated by the electric motor, avoiding the excessive rise in temperature [17][18][19][20]. Reducing the thermal capacity of the coolant fluid and increasing the speed of the coolant fluid are common methods for improving the heat transfer of a cooling system [21].…”

In this paper, the overall performance of an electric machine cooling system was examined in terms of heat transfer and fluid flow. The structure of the cooling system was based on the cooling jacket method. The cooling jacket contains spiral channels surrounding the stator and end-windings of the electric machine. Al2O3-water nanofluid is used inside the channels as the cooling fluid. The concentration of nanoparticles and the geometric structure of the cooling system have special effects on both aspects of heat transfer and fluid flow. Therefore, in this paper, the overall performance of the cooling system was evaluated by considering these effects. This study compared the importance of heat transfer and fluid flow performances on the overall performance of the cooling system. Numerical analyses were performed by 3D computational fluid dynamics and 3D fluid motion analysis. The analyses were carried out based on the 3D finite element method using the pressure-based solver of the Ansys Fluent software in steady mode.

An Overview of MnAl Permanent Magnets with a Study on Their Potential in Electrical Machines

In this paper, hard magnetic materials for future use in electrical machines are discussed. Commercialized permanent magnets used today are presented and new magnets are reviewed shortly. Specifically, the magnetic MnAl compound is investigated as a potential material for future generator designs. Experimental results of synthesized MnAl, carbon-doped MnAl and calculated values for MnAl are compared regarding their energy products. The results show that the experimental energy products are far from the theoretically calculated values with ideal conditions due to microstructure-related reasons. The performance of MnAl in a future permanent magnet (PM) generator is investigated with COMSOL, assuming ideal conditions. Simplifications, such as using an ideal hysteresis loop based on measured and calculated saturation magnetization values were done for the COMSOL simulation. The results are compared to those for a ferrite magnet and an NdFeB magnet. For an ideal MnAl hysteresis loop, it would be possible to replace ferrite with MnAl, with a reduced weight compared to ferrite. In conclusion, future work for simulations with assumptions and results closer to reality is suggested.
