Abstract

In this paper a look at energy efficiency in electric drives is taken strongly through energy parameters - efficiency ? and power factor k (in special case cos f). Considering electric drive as system of working mashine, motor and power converter, the influence of components is evaluated. Induction motor, as the most used in industry, has been treated. The necessary of variable speed drives in dynamic states for reducing electrical losses by help of power converters is presented. The importance of energy efficiency in electric drives on improving technological process, consumed and paid electric energy and global problem of enviroment pollution is elaborated.
