“…The switching frequency is 5 kHz, the fundamental frequency is 60 Hz, the DC-link voltage is 400 volts, the ambient temperature is 25 o C, and the IGBT's maximum temperature is 150 o C. The cooling system's fan speed is 1000 ft/min. In this study, four load torque values (10,15,20,25) Nm are used of this system to monitor changes in the junction temperature. It is found that the value of the junction temperature increases as the load torque rises; the maximum value of TJ was recorded at a torque of 10 Nm is (64.5 ℃), it recorded (71.7 ℃) at a torque of 15 Nm, it recorded (77.24 ℃) at a torque of 20 Nm and recorded (82.46 ℃) at a torque of 25 Nm.…”

“…Numerous industrial applications, including energy savers, motor soft starters, are utilizing different voltage modulation methods. Inverters controlled by support vector machine (SVM) provide the lowest harmonics and highest efficiency when compared to other modulation techniques [25]. Improvements in the quality and consistency of the drive circuit are becoming more and more necessary as a result of ongoing research on improving the performance of motor drives.…”

In order to discuss the effectiveness of inverter performance, it is essential to concentrate on its losses. Thus, knowing the junction temperature (TJ) value of the inverter switches insulated-gate bipolar transistor (IGBTs) under different loading conditions allows determining their reliability and designing the right heat sink. The old methods to calculate the TJ are inaccurate, difficult to implement, and require mathematical analysis. So, in this work, a new approach was used to calculate the TJ in a simplified way, using the SIMSCAPE environment in the MATLAB simulation. The IGBT in the SIMSCAPE environment is of an improved design and has a direct thermal port. The TJ estimation is more accurate and it relies only on the thermal impedance model, so we do not need to compute the power losses as was done in previous studies. This functionality is only accessible in more recent versions of MATLAB (2019-2023). With different motor load torques, the IGBT junction temperature is evaluated, and the effect of the selected heat sink on the value of TJ is evaluated when it is under the effect of natural cooling and air-forced cooling.

“…Motor cooling circuits, either liquid or forced air, can further enhance motor efficiencies. Advances in solid-state Silicon Carbide IGBT switching technologies have improved motor control performance as highlighted in a recent study [24], and for high altitude aircraft operations the high voltage DC (HVDC) motor transmission lines are susceptible to corona energy discharge losses [25]. An excellent performance analysis of electric motor technologies is provided in the White Paper produced by Motor Design Ltd. of the UK [26].…”

This paper provides a review of the state-of-theart in aircraft electrical propulsion (AEP). Initially, the limitations of on-board energy storage devices are highlighted and contextualised. The definitions of useful measures for determining the suitability of motor design, namely specific power and motor torque per unit rotor volume (TRW), are discussed and relevant examples are provided. The classifications of motors used for terrestrial vehicle applications are reviewed and their limitations highlighted regarding their suitability to AEP applications. A discussion on motor configurations for aerospace applications is provided which includes: synchronous motor stator winding configurations; axial flux motor configurations and the causes of energy losses. Additionally, the topologies and performance characteristics of existing aerospace motor technologies are examined. It was concluded that electrical motors provide an ideal means for achieving aircraft propulsion and that higher motor speeds are likely to be required for future commercial aircraft motor designs.
