US Patent 11353511 Methods and systems for electric propulsor fault detection

Systems and methods relate to electric propulsor fault detection. An exemplary system includes at least a first inverter configured to accept a direct current and produce an alternating current, a first propulsor, a first motor operatively connected with the first propulsor and powered by the alternating current, and at least a noise monitoring circuit electrically connected with the direct current and configured to detect electromagnetic noise and disconnect the at least an inverter from the direct current as a function of the electromagnetic noise.
