Phase Separation for Open Circuit Fault-tolerance in a Multirotor Air Vehicle Propulsion Chain Using Switched Reluctance Machines

Résumé

Electric aircraft nowadays use almost exclusively permanent magnet motors, which have good performance but open circuit faults render them inoperable. This is especially dangerous in multirotor drones, which are forced to utilize hardware redundancy by doubling the number of motors. A potential, more sustainable, alternative is to use independent phases within one motor, which enables the motor to operate in a reduced capacity after fault. This is verified through the design and testing of a switched reluctance motor for air vehicle applications. The actuating system is able to deliver more thrust than is required for hover even with 2 phases inoperable. This approach, coupled with fault-tolerant control, can be treated as an alternative to motor redundancy in safety critical systems.
