- Electrical motors operating at low temperatures and in aggressive environment, such as liquid natural gas for instance, should exhibit high reliability, efficiency, and good electromagnetic parameters, both in dynamic and static states as well. Low working temperature has significant influence on change of parameters of conductive materials, and electrical sheets. Changes of their parameters determine run and values of the current and torque during start of the cage induction motor. The paper presents results of laboratory tests, calculations, and computer simulations of parameters changes of conductive and magnetic materials submerged in liquid gas with temperature of-161°C. Results of calculation targeting to elaboration a way of the starting current decreasing and starting torque increasing of cage induction motors working at very low temperatures are given. The shape, cross-section and material of a rotor's cage are the most influential elements on the above mentioned motor's parameters. That is why the paper presents chosen results of the influence analyze of these elements on the torque and current values and runs of the studied motor.
