Vector Control of Three-Phase AC Machines | SpringerLink

It seems that you're in Germany. We have a dedicated site for Germany. This book addresses the vector control of three-phase AC machines, in particular induction motors with squirrel-cage rotors IM , permanent magnet synchronous motors PMSM and doubly-fed induction machines DFIM , from a practical design and development perspective. The main focus is on the application of IM and PMSM in electrical drive systems, where field-orientated control has been successfully established in practice. The book is useful for practitioners as well as development engineers and designers in the area of electrical drives and wind-power technology.

Vector Control of Three-Phase AC Machines

This monograph covers the area of vector control of three-phase AC machines, in particular induction motors with squirrel-cage rotor IM , permanent excited synchronous motors PMSM and doubly-fed induction machines DFIM , from the viewpoint of the practical design and development. Main focus is on the application of the IM and the PMSM in electrical drive systems, where the method of the field-orientated control has been successfully established in the practice, and on the use of the grid voltage orientated controlled DFIM in the wind power plants. The monograph is suitable for the practical work. Development engineers and designers of the electrical drive and of the wind power technology are mainly mentioned with the book. It can be recommended for qualified employees from the research and for students. Skip to main content Skip to table of contents.

Direct torque control DTC is one method used in variable frequency drives to control the torque and thus finally the speed of three-phase AC electric motors. This involves calculating an estimate of the motor's magnetic flux and torque based on the measured voltage and current of the motor. Stator flux linkage is estimated by integrating the stator voltages. Torque is estimated as a cross product of estimated stator flux linkage vector and measured motor current vector. The estimated flux magnitude and torque are then compared with their reference values. If either the estimated flux or torque deviates too far from the reference tolerance , the transistors of the variable frequency drive are turned off and on in such a way that the flux and torque errors will return in their tolerant bands as fast as possible.
