Abstract: An aircraft or other vehicle includes a system and method for selectively allocating which friction brakes of a plurality of friction brakes are utilized in response to a braking demand. Said differently, the present disclosure provides a system and method that includes dynamically switching which friction brakes of a plurality of friction brakes are active (e.g., in use) at a given time in response to a braking demand. This dynamic switching may not only be based on the received braking demand (e.g., from a pilot or auto-braking module), but may also be based on one or more of the following: respective measured brake parameters of the plurality of friction brakes (e.g., temperature, extent-of-wear), aircraft parameters, external parameters, and respective calculated brake conditions.

Abstract: An electric motor control system, including an electric motor having a first winding set including first and second parallel windings, the first and second windings operable to each current based on the combined phase current, and a differential current sensor operably coupled to the first winding and the second winding. The differential current sensor measuring a differential current flowing through the first winding and the second winding and operable to transmit a signal indicative of the differential current based on the measuring. The system also includes a motor controller connected to the electric motor, the motor controller operable to direct the combined phase current through the phase lead, receive the differential current signal, determine if the differential current flowing through the winding set exceeds a selected threshold, and identify a health status of the motor winding set as degraded if the differential current exceeds the selected threshold.
