Energy Efficiency in Electric Drives

  title={Energy Efficiency in Electric Drives},
  author={Slobodan Mirchevski},
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…
