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.

“…Induction motors are the devices that convert electrical energy into mechanical energy. Induction motors offer wider torque range and accurate speed control, provide recharging of battery during breaking, require low maintenance, and have high efficiency [1]. They are also smaller in size when compared with permanent magnet DC (Direct Current) motors and are less expensive, Figure 1.…”

“…The induction motors utilized in cars require high load capacity. When these motors operate at higher speeds, they generate heat which results in an increase in losses such as copper and iron loss, thereby increasing the temperature in the rotor and stator of the motor [1]. With the increase in temperature, various parts of the induction motor could experience phase change, softening, melting, and other forms of degradation that will affect the performance of the motor.…”

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.

“…Spindle thermal deformation caused by the error is often small, but the impact on the machining accuracy is prominent, and in serious cases, even causes damage to the spindle. Therefore, it is especially critical to provide efficient heat evacuation and address the thermal contortion of the motor spindle caused by temperature increase [4][5][6][7][8].…”

In high-speed motors, there is a huge amount of heat generation from core and winding losses, which may result in thermal failures or motor performance deterioration. In the prevention of heat accumulation, efficient cooling technology is critical for smooth and reliable motor movement. This paper summarizes the diverse application of high-speed motor and thermal requirements, such as in electrical devices, turbo-machinery, and high-precision machine tools. Three paths of case convection—cooling, internal ventilation cooling and spindle core cooling—are analyzed. Methods for configuring thermal resistance and improving cooling efficiency are summarized. Among them, coolant flow characteristics and flow channel shapes, gas supply ventilation systems, and methods to reduce air resistance, as well as axial cooling and integrated heat pipe structures, are extensively investigated. Finally, the development prospects of high-speed motor cooling are also forecasted. At present, the primary research directions are to reduce the heat generated by the heat source, utilize the latent heat of the coolant, optimize the cooling flow path of the shell, design an axial air-cooling circulation system, and enhance the heat dissipation of the spindle.
