1. 1. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Muhammad Umar Farooq; [2023]
   Keywords : Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

   Abstract : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces.

   Abstract : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. READ MORE

4. 3. Harmonisk strömsimulering i inverterbaserade värmepumpar

   University essay from Umeå universitet/Institutionen för fysik

   Author : Alexander Magnusson; [2023]
   Keywords : Current harmonics; inverter-driven compressor; black box simulation;

   Abstract : An electrical distribution network supplies power to many households at a time. Each house has various types of electrical appliances which consume different levels of power depending on its function and the load it supplies. An ideal case would be when no appliances cause power disturbances, however, in reality, many electrical appliances (e.g. READ MORE

5. 4. Modelling and Simulation of Hydrogen Electrolyzers for Power System Applications

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