“…That means the MPS method is more suitable for fluid-structure coupling problems with large deformed flow field and complex motion [21,22] . Despite that the mesh model established by FEA method takes a long time to solve the moving mesh problems, it still has an advantage in solving heat transfer and chemical reaction problems [23,24,25] .…”

In order to study the influences of the initial liquid level on lube characteristics and oil-churning resistance moment of gear reducer, the heat generating power of one special kind of planet gear reducer under the special working condition is calculated. The fluid temperature at different initial liquid levels is calculated by FEA method. According to the relation between the physical parameters of the lube and the fluid temperature, the corresponding relation between the physical parameters of the lube and the initial liquid level is deduced. Based on the FEA results, the physical parameters of the lube are set to conduct the co-simulation of the oil-churning process of the planetary reducer under different initial liquid levels by MPS method. Depend on the simulation results, the influence of initial liquid level on lubricating flow state and oil-churning resistance moment of planetary reducer is analysed, and the initial liquid level is sifted. These studies provide methods and reference for lubrication medium set in transmission boxes, such as planet gear reducer and so on.

The paper gives a comprehensive review of lightweight materials/design of permanent-magnet-synchronous-motors and different temperature-reducing (cooling) techniques. The paper discusses and compares various simulations and performance analyses of different practically implemented solutions. Temperature and performance analyses for cooling systems using phase-changing materials, cooling jackets, and other coolants are investigated, and the use of lightweight materials and composites is compared. A discussion on numerical methods and results (finite element method analysis), in order to get a more-precise thermal mapping model for different machine structures is presented. Finally, the best temperature-reducing-cooling systems methods along with the good lightweight designs which increase the overall efficiency of the motor are discussed and commented on.

“…Hence, the performance and life span of the induction motor are dependent on its thermal conditions. The induction motor's temperature rises as a result of heat sources such as stator's iron losses, mechanical and windage loss, and winding joule loss [3,4]. Currently, induction motors are cooled using techniques such as air cooling, water cooling, and air-water cooling.…”

The driving motor is one of the most crucial components of an electric vehicle (EV). The most commonly used type of motor in EVs is the induction motor. These motors generate heat during operation due to the flow of electrical current through the motor’s coils, as well as friction and other factors. For long-run and high efficiency of the motor, cooling becomes more important. This article utilized ANSYS Motor-CAD to map the temperature signature of an induction motor and investigated the thermal efficiency of using nanofluids as a cooling medium. The thermal conductivity of nanofluids has been found to be superior to that of more conventional cooling fluids such as air and water. This research explores the effect of using Al2O3, ZnO, and CuO concentrations in nanofluids (water as a base fluid) on the thermal efficacy and performance of motor. According to the findings, using nanofluids may considerably increase the efficiency of the motor, thereby lowering temperature rise and boosting system effectiveness. Based on the simulation analysis using ANSYS Motor-CAD, the results demonstrate that the utilization of CuO nanofluid as a cooling medium in the induction motor led to a reduction of 10% in the temperature of the motor housing. The maximum reduction in the temperature was found up to 10% when nanofluids were used, which confirms CuO as an excellent option of nanofluids for use as motor cooling and other applications where effective heat transmission is crucial.
