They convert the fixed mains voltage with a fixed frequency into a three-phase system with a variable voltage and frequency. This makes it possible to control or regulate the speed of three-phase motors infinitely variably. Frequency converters with a DC voltage intermediate circuit are used most frequently. The descriptions in the work book are therefore restricted to frequency converters with this design principle. The following contents are communicated in 12 application-oriented project exercises: function, applications, energy optimization and programming. The workbook contains: – Sample solutions – Training notes – Worksheets for students Campus license: de 8114398 en 8114399 es 8114400 fr 8114401 Course on Festo LX: aSpeed Control of Three-Phase Asynchronous Motors With Frequency Converters Glossary of Electrical Drive Technology Modern drive technology is characterized by the increased integration of electrical and mechanical components into drive systems. New and improved drive capabilities can be achieved through the use of compact power electronics, innovative motor concepts, optimized mechanical components, new materials, and high-performance communication technology. This book lists the main concepts in glossary format and provides brief explanations to facilitate a better understanding of these drives. However since there is more to an electrical drive that just the electric motor, it also touches on areas such as measurement systems, power electronics, gearboxes, controllers, and components for transmitting power.
