2. Organising of electrical machine  failure investigations and associated experimental work

During the mid-late 1970's several  manufacturers of large electrical generators were experiencing problems with large generators failing due to core faults/core end heating.  Antony Anderson organised the extensive and rigorous core failure investigations and associated in-works and site experimental work carried out at that time by NEI Parsons.  These investigations involved coordinating a multi-disciplinary team of engineers and metallurgists and gathering and reporting the results.  See Generator Core Faults

3. Wide background of electrical machines experience - from timing motors to superconducting machines

For four years Antony Anderson was Group Leader of the Electromagnetics Group, R & D Laboratories NEI Parsons. This involved organising the design, installation and use of special purpose instrumentation of large generators to measure temperatures, flux densities and eddy currents, especially in the end regions and under transient conditions. Incidental studies were undertaken on arcing in hydrogen and factors affecting metal-to-metal contact resistance relating to rotor damper windings. 

For 3 years he co-ordinated  feasibility studies and experimental testing relating to  Superconducting AC Generators at the International Research and Development Co. Ltd. During this period the properties of a novel helical stator winding were investigated. He also acted as an external consultant on small timing motors for Edgecumbe Peebles and on  armature flashover problems that occurred on the DC lift motors used on the Tracked Hovercraft. 

As an NRDC Fellow at the University of Dundee, he designed synchronous reluctance motors with axially laminated rotors. He investigated the transient performance of reluctance and induction motors  and developed a practical method of finger-printing the torque speed characteristics of machines during run-up.  Prior to this work, he was involved in the early development of variable speed switched-field reluctance motors with thyristor commutation. 

For two years he was employed as a Plant Application Engineer with the Plant Application Engineering Department of AEI Rugby. This involved the specification and simulation of the transient performance of a large number of AC and DC control system configurations for various different industries, in particular for the metal rolling industry and for ship propulsion drives. Extensive knowledge was gained relating to the electronic simulation of electro-mechanical systems under transient conditions.
