Achievement of electric energy savings through controlling frequency convertor in the operation process of asynchronous motors in textile enterprises

Abstract In article are brought frequency regulation of the asynchronous electric motor and that reach to energy saving itself. Frequency management is energy saving so regulation of the frequency of the rotation of the asynchronous engine are provided increasing coefficient of efficiency and reduction of the loss to powers. A machine asynchronous is often used today as a power scale ranging with a motor from some Watts to several thousand kW. For power applications exceeding several kW, asynchronous motors run solely on three-phase AC power supplies. Owing to the sensitivity of a process or the critical nature of certain applications, the network may be supported with an Uninterruptible Power Supply.
