1. Hur kan elförbrukningen i lågspänningsanläggningar reduceras?
Uppsats för yrkesexamina på grundnivå, Lunds universitet/Trafik och vägSammanfattning : I denna rapport analyseras hur dimensioneringen av Rectiverter och UPS systemens storlek är anpassade för driftsplatsernas faktiska elförbrukning och vilka potentiella lösningar som finns för att effektivisera användandet av systemen för att minska elförbrukningen. Effektiviserandet av driftplatsernas system kommer att leda till en kostnadseffektivare anläggning. LÄS MER
2. Electric conversion of combustion engine cars
M1-uppsats, KTH/Hållbar produktionsutveckling (ML)Sammanfattning : The electrification of personal transport vehicles is one of the strategies to counteract global warming and dependance on fossil fuels. Diesel powered cars are already prohibited in several big cities and the prices for fuel are constantly climbing. LÄS MER
3. Closed Loop Control of PMSM Motor : Field Oriented Control Using Hall Sensors
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : Fossil-fuel vehicles are one of the main causes of CO2 emissions nowadays. As we are moving toward cleaner environment electrification of vehicles are becoming more and more popular. With the environment in mind, the recent improvement in battery technology and electronics has drawn a lot of attention to Brushless DC or BLDC motors. LÄS MER
4. Implementing VLF as diagnostic test for HV motors and generators : A comparative study of diagnostic tests performed at different frequencies
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för teknikvetenskaperSammanfattning : High voltage testing of the stator winding insulation is one of the most recognized methods used to determine the state of degradation in the insulation. HV tests performed at 0.1 Hz do have potential advantages compared to more traditional 50 Hz tests. LÄS MER
5. Investigation of electromagnetic compatibility (EMC) of low-voltage (<60V) DC electric motors in construction machinery application
Master-uppsats, Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakultetenSammanfattning : The brushed DC motor is a source of electromagnetic emission that may cause interference. The main issues with brushed DC motor are arcing, which occurs between the brushes and commutator, and inrush current. It is possible to decrease the electromagnetic emissions by addressing the source (brushed dc motor) and the installation. LÄS MER
