Experimental Studies of an Induction Motor with Cryogenic Cooling
Abstract
The article addresses matters concerned with the development and research tests in air and liquid nitrogen of an 18 kW submersible cryogenic induction motor. The motor core can be used as a drive of a pump for transferring liquefied natural gas (LNG). The induction motor parameters and characteristics are calculated out taking into account an ambient temperature of –196°C. Since the tests are carried out at two temperatures (20°C and –196°C), the motor characteristics are also calculated for a temperature of 20°C. To verify and refine the calculation results, a finite element analysis was performed in the ANSYS Maxwell software package environment. The finite element method was used to check the saturation of materials and the motor output characteristics. In elaborating the design, the materials suitable for use at cryogenic temperatures were analyzed. The materials considered in the analysis included electrical steels, electrical insulation materials, winding and connection wires, compounds, varnishes, adhesives and various mounting items. After the development of design documentation and manufacturing, research tests of the submersible induction motor were carried out in air and in a liquid nitrogen environment. During the tests, the condition of the insulation materials was checked, and pie charts were constructed to assess the motor characteristics based on the test results.
