Abstract
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 disengage the at least an inverter as a function of the electromagnetic noise.
Claims20
An electric propulsor fault detection system comprising:
- at least a first inverter configured to:
- accept a direct current;
- and
- power a first motor;
- a first propulsor, wherein the first propulsor is mounted to an electric aircraft and configured to produce lift;
- the first motor operatively connected with the first propulsor;
- and
- at least a noise monitoring circuit electrically connected with the direct current and configured to:
- detect noise having a frequency within a specified range;
- and
- disengage the at least an inverter as a function of the detected noise.
A method of electric propulsor fault detection comprising:
- accepting, using at least a first inverter, a direct current;
- powering, using the at least a first inverter, a first motor operatively connected with a first propulsor, wherein the first propulsor is mounted to an electric aircraft and configured to produce lift;
- detecting, using at least a noise monitoring circuit electrically connected with the direct current, noise having a frequency within a specified range;
- and
- disengage, using the at least a noise monitoring circuit, the at least an inverter as a function of the detected noise.
