Position sensorless electrically excited synchronous motor drive for industrial use based on direct flux linkage and torque control
(Lappeenranta University of Technology, 1999-04-16)
Synchronous machines with an AC converter are used mainly in large drives, for example in ship propulsion drives as well as in rolling mill drives in steel industry. These motors are used because of their high efficiency, ...
Salient Pole Synchronous Machine Modelling in an Industrial Direct Torque Controlled Drive Application
(Lappeenranta University of Technology, 1999-03-26)
Synchronous motors are used mainly in large drives, for example in ship propulsion systems and in steel factories' rolling mills because of their high efficiency, high overload capacity and good performance in the field ...
Analysis and Control of Excitation, Field Weakening and Stability in Direct Torque Controlled Electrically Excited Synchronous Motor Drives
(Lappeenranta University of Technology, 1998)
Direct torque control (DTC) is a new control method for rotating field electrical machines. DTC controls directly the motor stator flux linkage with the stator voltage, and no stator current controllers are used. With the ...
