Journal Article
Zhang, G., Zappalá, D., Crabtree, C., Donaghy-Spargo, C., Hogg, S., & Duffy, A. (2020). Validation of a non-contact technique for torque measurements in wind turbines using an enhanced transient FSV approach. Measurement, 151, Article 107261. https://doi.org/10.1016/j.measurement.2019.107261

In-service turbine monitoring is essential for maximizing the wind energy contribution to the global energy budget. Measurement of turbine shaft torque under transient wind conditions is fundamental to develop reliable condition monitoring techniques...

Use of Fractional-Conductor Windings and Semi-Magnetic Slot Wedges in Synchronous Machines (2019)
Journal Article
Donaghy-Spargo, C., & Spargo, A. (2019). Use of Fractional-Conductor Windings and Semi-Magnetic Slot Wedges in Synchronous Machines. Journal of Engineering, 2019(17), 4396-4400. https://doi.org/10.1049/joe.2018.8205

This paper discusses two methods of altering the harmonic content of the spatial air-gap flux density waveform in synchronous machines (generators and motors). First, fractional-conductor windings are analysed for adoption as a replacement for a conv...
