A METHOD AND DEVICE FOR CONTROLLING THE MAGNETIC FLUX IN A ROTATING HIGH VOLTAGE ELECTRIC ALTERNATING CURRENT MACHINE WITH PERMANENT MAGNET ROTOR

摘要

A rotating electric machine for direct connection to high-voltage networks, in which the magnetic circuit adapted for high voltage comprises a permanent magnetic rotor, stator and main and auxiliary flux control windings in operative relation. At least one of the windings is a conductor surrounded by a magnetically permeable, field confining insulation system.
