  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.

  4. 3. Electromagnetic Shielding of Fine Wires for Electrophysiological Sensing

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Simon Mogren; [2020]
    Keywords : ;

    Abstract : Tests have been performed to determine whether electromagnetic shielding of fine wires for electrophysiological sensing is a possible way to reduce the external noise in recording of nervous signals. By shielding the wires with a layer of silver, forming a coaxial cable, a reduction of the received power on the lead of 11. READ MORE

  5. 4. Bearing current and shaft voltage measurement in electrical motors

    University essay from Högskolan Väst/Avdelningen för data-, elektro- och lantmäteriteknik

    Author : Edo Kolic; [2017]
    Keywords : Modulated drive; electrical motors; production;

    Abstract : Due to the fast-rising voltage pulses of pulse width modulated drives, the generated shaft voltage of electrical motors causes electrical discharge currents in bearings. These discharges can cause bearing failure leading to costly maintenance and unexpected production stops. READ MORE

  6. 5. Earth Fault Currents in Three Phase systems

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Mohammad Kamrul Hasan; Faham Hossain; [2015]
    Keywords : Earth; Fault;

    Abstract : This paper focuses on the grounding methods for distribution systems and the characteristics and behavior of earth fault currents. At First different existing grounding methods such as isolated neutral, solidly grounded, Resonant grounding, low and high impedance groundings are introduced. READ MORE
