Ask any engineer about electric motors and most of us visualise low- or medium-voltage three-phase equipment, either precision synchronous motors, driving machines or, more likely, standard asynchronous induction motors running pumps, fans and sometimes compressors. We see them everywhere, on all manner of industrial and utility plant, as well as heating and ventilating systems.

CERN's Large Hadron Collider (LHC) - the planet's most powerful subatomic particle accelerator - made it into the record books when, at 10.28am on Wednesday 10 September, in front of the world's hyped-up media, the first beam was successfully steered around its 27km ring. Then, just nine short days later, there was an incident that resulted in a large leak of helium into the beam tunnel, forcing shutdown of this amazing project until spring of next year.
