Sažetak
At the power supply of the low-voltage asynchronous motors (with homogeneous yokes) from the network, shaft currents resulting in damage of bearings, can emerge. The main cause of these currents is the eccentric position of rotor in the stator bore (static and dynamic eccentricity). The required condition for the emergence of these current in nonlinearity of magnetizing curve of electrical steel of the motor stack lamination. The article describes perfomed measurements on the four-pole motor. First, the measuring equipment: Rogowski coil and his mounting, AD converter NI- DAQPad-6015 and power analyzers NORMA-D6000 have been described. Then, ways of measurements and processing and processing of measurements have been explained. Data obtained by measurements have been presented at the nominal load, for the star- and delta-connected stator winding, measured with AD converter NI-DAQPad-6015 and power analyzer NORMA-D6000. Differences in measured results of shaft currents measured by the power analyser NORMA-D6000 related to measurements with the AD converter NI-DAQPad-6015 are explained.
