High speed electrical machines are replacing existing subsystems in aircraft. Electrical drives need to have high availability and good power density to be considered a viable replacement. To achieve high availability fault tolerance is added to the system design. Power density is increased by spatial integration of subparts. Fault tolerance extends to both machine and power electronics design. By...
System integration and fault tolerance aims to help achieve high levels of availability and power density in aerospace applications. A 50kW integrated machine and drive with fault tolerance is described. For monitoring system health and diagnostics, an array of sensors is embedded. On state voltages and device currents are compared to ensure equal current sharing. By implementation of a power module...
