摘要： In an aspect, this disclosure is related to apparatus and method for optimizing motor performance in an electric vertical takeoff and landing aircraft. Apparatus includes a motor, an inverter, a sensor, and a flight controller. Flight controller is configured to receive an operational datum from a sensor, which detects a physical phenomenon and generates an operational datum. Flight controller is configured to generate an optimized switching frequency for the inverter based on the operational datum. Flight controller is configured to adjust the switching frequency of the inverter based on the optimized switching frequency.

摘要： Provided in this disclosure is a dual-motor propulsion assembly, and corresponding methods of operation, that is configured for use in an electric aircraft. Dual-motor propulsion assembly provides redundant systems by including vertically stack motors, where one motor powers a propulsor of the assembly if the other motor malfunctions or becomes inoperative.

摘要： 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.

摘要： Provided in this disclosure is a dual-motor propulsion assembly, and corresponding methods of operation, that is configured for use in an electric aircraft. Dual-motor propulsion assembly provides redundant systems by including vertically stacked motors, wherein one motor may still power a propulsor of the assembly if the other motor malfunctions or becomes inoperative.
