Abstract: A propulsion system includes a first portion and a second portion that are independently controlled from one another. The first portion includes a first inverter and a first electric motor. The second portion includes a second inverter, a second electric motor, and a second disconnect link. A control system is configured to detect a fault in the first portion, the second portion, or combinations thereof, and determine a response to the fault. In one example, on detection of the fault in the second portion, the second disconnect link is disengaged to reduce electromagnetic drag torque by the second electric motor.
