The problem of shaft voltage origination in electrical machines was known and studied already at the beginning of the past century. The shaft voltage can occur also by synchronous generator with exciting winding fed from static exciter. When we will not respect any specific designing and mounting principles it can happen to current flow through bearings. Conductive path is created by closed circuit compounded from motor frame, bearing shields, bearings and shaft. In the other cases it can be concerned a circuit consisted from winding, air gap, bearing, capacitance or possible capacitance of other parts against ground. Different parts of bearings can be damaged by these currents and so it comes to operation state deterioration. In our paper we want to show measuring results of small and large power motors.
