1. 1. Evaluation of electric actuation for fighter aircraft

   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Dennis Moliner Pettersson; Anton Nygårds; [2023]
   Keywords : EMA; actuator; actuation; MEA; aircraft; PMSM; SHA;

   Abstract : The tendency of recent years towards electrification of aircraft components and subsys-tems has opened the door for a wider usability of electro-mechanical actuators (EMAs) inthat context. EMAs are already in use in aircraft industries but mainly in civil aviation forsecondary control systems and non-critical applications. READ MORE

3. 2. Heat-pipes in electric machines : Heat management in electric traction motors

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Anton Olofsson; [2022]
   Keywords : Heat-pipe; Heat pipe; FEM; LPM; Traction motors; Induction motor; Heat management;

   Abstract : The world is continually changing towards more energy efficient alternatives and less pollution. For the traction market, electric powertrains have become the go-to method, superior to both steam and diesel-electric hybrid systems. READ MORE

4. 3. CFD Simulations of Velocity and Temperature Distributions of the AuraGen Axial Flux Machine

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Huanyu Chen; [2022]
   Keywords : CFD simulation; Induction machine; Temperature distribution; Velocity distribution; CFD-simulering; Hastighetsfördelning; Induktionsmaskin; Temperaturfördelning;

   Abstract : Axial flux induction machines are attractive solutions for electric vehicle applications nowadays. Thanks to their high torque density and no need for rare-earth material for permanent magnets, axial flux induction machines are the most used electric machine type with good performance and low prices.

5. 4. Optimal torque split strategy for BEV powertrain considering thermal effects

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Dhananjay Yadav; [2021]
   Keywords : Optimal torque-split control strategy; battery electric vehicles; thermal model of electric machines; system identification; model order reduction; co-simulation.; Optimal vridmomentsdelningsstyrningsstrategi; batteridrivna fordon; termiska modeller av elektriska maskiner; systemidentifiering; minskning av modellorder; samsimulering.;

   Abstract : A common architecture for electric vehicles is to have two electric machines one each on the front and rear axle. Despite the redundancy, this configuration ensures performance. Being energy efficient is equally important for electric vehicles to deliver a sufficiently high range. READ MORE

6. 5. Modelling and simulations for analysing thermal performance enhancement in air ducts with cold surface and hot air

   University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper

   Author : Olle Rosell; [2018]
   Keywords : Heat transfer; air-duct; simulations;

   Abstract : The world today has large challenges in order to manage a changing climate and the consequences that the climate change has on the environment and human living standards. This climate change is largely affected by the emissions of greenhouse gases, which come from usage of fossil fuels. READ MORE
