Energy Characteristics of Electric Drive of Oscillatory Motion at the Shock-Free Start

Abstract

The peculiarity of operation of oscillatory electric drive with doubly-fed motor at realization of algorithm of shock-free start was considered. The method of evaluating of energy parameters of such motors operating at the resonance mode with учетом of quantitative and qualitative components of the process of energy conversion by an electric motor (doubly-fed motor) is proposed. The calculation of energy characteristics of electric drive of this type was made, the results of calculation show an increase of energy efficiency (an average, generalized efficiency coefficient [eta]E increased by 10 %), which confirms the practical significance of the research object.
