| Abstract |
The double fed A.C. motor with wound rotor (DFAM) is suitable for dynamic high
power industrial applications which require a wide "constant power" speed range involving deep field weakening. The considered drives are sized for 250 till 5000 kW industrial applications which require constant power operation in a speed range ratio up to 1 to 6. By supplying its rotor and its stator with separate converters, a DFAM is able to reach these specifications with minor motor and power electronics converters oversizing, while a squirrel cage induction motor needs significant motor and power electronics converter oversizing. Besides, with a lower voltage and current reserve on both converters the drive offers a higher dynamic and faster flux -weakening - rebuilding cycles because of absence of damping squirrel cage or damping windings. |
