  6. 10. 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
