Abstrakty
The squirrel-cage asynchronous motors working in liquid natural gasses place the particular requirements concerned both active materials and insulation, fastening, electrical connections etc. Generator sheets, used in magnetic core of motor, their insulation and way of packeting are only few essential elements which have the influence on parameters and durability of the motors working in range of temperatures -160°C - -196°C. In the paper, works concern testing and selection of generator sheets for realization of motor working in liquid natural gasses with temperature -161°C are presented. Apart from this, the results of tests conducted in liquid nitrogen environment and room temperature are included. To choose the optimal kind and thickness of electrical sheet, the behavior of electrical sheets with different thickness and kind of insulation were examined. The magnetic parameters of the tested electrical sheets, such as: magnetic induction, total energy loss with division on hysteresis and eddy current loss were determined. On the grounds of the obtained results and analysis of literature the kind and thickness of electrical sheet used in construction of magnetic core of motors working in liquid gasses was chosen.
