Rotor Design for Sensorless Position Estimation in Permanent-Magnet Machines

A body of research into position sensorless control at Bristol has contributed to commercial adoption of sensorless control in aircraft electro-mechanical actuators and starter-generators. Paper is one of first to incorporate sensorless requirements within parametric optimisation of electrical machine rotor design, and identifies electromagnetic design trade-off between fundamental torque production and idealised position signature. PhD studentship, fully-funded by Airbus, is now establishing performance trade-offs of incorporating sensorless position estimation in aircraft electric actuation. Sensorless position methods are also being exploited as part of Safran Power (formerly Goodrich) funded University Research Centre [contact: ‎R&T and Systems Manager].
