Abstract

Possible origins of shaft currents in squirrel-cage low-voltage induction machines are analysed. The mechanism of generation of shaft currents fundamental frequency and slip frequency at 2-pole and 4-pole machines is explained, as well the influence of broken rotor bars or end rings on shaft currents.
