  • Methods and systems for detecting a winding resistance and winding temperature of an alternating current electrical machine
    Patent number: 11817803
    Abstract: A method includes determining a vector state of an alternating current (AC) electrical machine. The method includes, when the vector state is a zero-vector state, obtaining a plurality of phase current samples of the AC electrical machine, determining a decay time constant based on the plurality of phase current samples, and determining a resistance of a winding of the AC electrical machine based on the decay time constant. The method further includes selectively activating a plurality of switches of an inverter configured to provide power to the AC electrical machine based at least on the resistance of the winding of the AC electrical machine.
