3. 17. Investigation of electromagnetic compatibility (EMC) of low-voltage (<60V) DC electric motors in construction machinery application

   University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

   Author : David Luong; Ibrahim Salloum; [2019]
   Keywords : EMC; brushed dc motor; arcing; inrush currents; X2Y capacitor; NTC thermistor; common mode ferrites; differential mode ferrites; grounding; cable placement; motor design parameters;

   Abstract : 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. READ MORE

4. 18. Impact of Surrounding Objects on Inductive Wireless Power Transfer

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Brenda Odhiambo; [2019]
   Keywords : Wireless power transfer; inductive coupling; Qi Specification; effect of metals; Technology and Engineering;

   Abstract : Many new models of smartphones and small electronic devices are using their wireless charging feature as a key selling point. This is due to the convenience of cable-free charging as well as not requiring multiple power adapters for charging different devices. READ MORE

5. 19. Power cables in battery electric vehicles used in underground mining : Analysis of electromagnetic dynamics in high-power cables and development of application-specific design strategies for reduction of EMI

   University essay from Uppsala universitet/Elektricitetslära

   Author : Chisom Miriam Ekweoba; [2019]
   Keywords : ;

   Abstract : The electrification of the automotive industry is growing in popularity, considering the environmental impacts of the conventional diesel-powered automobile. However, from the electromagnetic compatibility (EMC) viewpoint, it is observed that the use of variable-frequency drives (VFD) and relatively high-power cables to propel electrical motors has led to a considerable rise in electromagnetic interference (EMI) within and outside the machine.
