Much interest has been directed towards the use of
rotationally induced e.m.f.s in the stator windings of an
excited-rotor synchronous machine for the natural commutation
of a directly coupled thyristor inverter to give a
variable-speed drive. The attractions of this scheme are that
relatively inexpensive power handling devices can be used
with a conventional machine to give a drive with inherently
flexible characteristics.
