The subject of this paper is the analysis of the current spectrum of asynchronous motors with an emphasis on cage asynchronous machines. In this paper, the stator current spectrum will be analyzed on the example of a squirrel-cage motor with nominal power 11 kW, which will be considered in nominal load mode and failure mode (damage to rotor conductors). In these modes, every significant component of the current spectrum will be traced, i.e. state its origin.
