Lecture - 35 Vector Control of Induction Motor
VFDs are used in applications ranging from small appliances to large compressors. Over the last four decades, power electronics technology has reduced VFD cost and size and has improved performance through advances in semiconductor switching devices, drive topologies, simulation and control techniques, and control hardware and software. Some types of single-phase motors or synchronous motors can be advantageous in some situations, but generally three-phase induction motors are preferred as the most economical.

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.
