Sažetak The main causes of shaft currents in the low-voltage asynchronous motors (with homogeneous yokes) supplied from the net are the eccentric position of rotor in the stator bore and nonlinearity of magnetizing curve of electrical steel of the motor stack lamination. Circular magnetic flux emerged by those causes, produces shaft currents closed in the circuit: shaft, bearing, bearing shield, housing, bearing shield, bearing and shaft. The article describes the calculation procedure of circular magnetic flux, which determines shaft currents, conducted by the Finite element method by means of which quantity and frequency spectrum of that flux can be analyzed.
