Abstract

The present disclosure relates to an electronic circuit for detecting the current winding temperature of phase windings and/or other characteristics of an electronically commutated electric motor, which is connected, or can be connected, to a frequency converter, comprising one or more capacitive two-terminal networks with a temperature-dependent impedance, each network being arranged parallel to two winding terminals (u, v, w) of the phase windings, as well as a detector for detecting the current responses in the motor feeds on the basis of steep-flanked voltage changes at the output of the frequency converter.
