  1. 21. 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

  3. 22. Study of Analytical Models for Harmonic Losses Calculations in Traction Induction Motors

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Anaïs Maroteaux; [2016]
    Keywords : Analytical model; Bertotti; curve fitting; FEM 2D; harmonic losses; induction mo-tor; iron losses; Joule losses; skin and proximity effects.; Analytisk modell; Bertotti; kurvanpassning; FEM 2D; harmoniska förluster; asynkro-nmotor; järnförluster; Joule förluster; skineffekt och proximity effekt.;

    Abstract : This Master Thesis deals with the study of analytical and finite-element (FE) models for calculation of losses in traction induction motors. Motors are fed through inverters for this type of application. Therefore, both fundamental and harmonic losses are considered. The study is done with one particular motor and one initial analytical model. READ MORE

  4. 23. Simulation of 3ph induction motor in Matlab with VVVF starting method

    University essay from Högskolan i Halmstad/Energivetenskap

    Abstract : Nowadays, three-phase induction motors are widely used on industrial and other types of processes. Therefore, accurate knowledge of an induction motor performance is very essential to have an idea of its operation conditions. READ MORE

  5. 24. Simulation of an Electrical Machine : with superconducting magnetic bearings

    University essay from Uppsala universitet/Elektricitetslära

    Author : Mesut Bahceci; [2015]
    Keywords : induction motor; superconducting bearings; air-gap;

    Abstract : This master thesis investigates if there is an induction motor configuration that can be used with a flywheel energy storage system, that uses passve superconducting magnetic bearings (SMBs). The configurations should be able to be designed with induction motor building blocks that are commercially available. READ MORE
