Abstract: A motor drive for driving a permanent magnet electrical machine includes an inverter having switches that are selectively operated to control current flow and terminal voltages in the electrical machine and a controller operatively connected to the inverter to control switching of the switches to control the current flow and terminal voltages in the electrical machine. The controller receives inputs regarding at least one of currents and voltages provided to the electrical machine on one or more phases, analyzes the voltages and currents to identify a fault in the electrical machine, and controls switching of the plurality of switches in the inverter to modify current flow and terminal voltages in the electrical machine based on the identified fault, with the modified current flow and terminal voltages in the electrical machine preventing demagnetization of the permanent magnets in the electrical machine.

Abstract: A method of detecting a vibration node between a non-collocated sensor-actuator pair of a rotatable component includes applying an excitation signal to an actuator of the sensor actuator pair. The method also includes obtaining frequency response data from the sensor-actuator pair. The method further includes analyzing the frequency response data to ascertain a resonant frequency of the rotatable component. The method includes identifying a resonance/anti-resonance peak pair in the frequency response data for the non-collocated sensor-actuator pair. Furthermore, the method includes determining whether the vibration node is located between a sensor and the actuator of the non-collocated sensor-actuator pair based on the resonance/anti-resonance peak pair.

The second electric machine is electrically coupled with the first electric machine such that electrical power is transmittable therebetween. The second power subsystem has a third electric machine mechanically coupled with one of the spools. The third electric machine is electrically coupled with a load positioned offboard the gas turbine engine. The first power subsystem and the second power subsystem are electrically decoupled from one another.
