Abstract
The paper refers to new options of functional testing of asynchronous motor using a stray electromagnetic field as the carrier of diagnostic information on the surface of machine frame with simultaneous comparisons of utility, advantages and disadvantages of the existing and most common method of diagnostics performed using the measurement of the machine supply current. This method is patented as Czech Patent CZ 303 470, ÚPV 2012.
