摘要
Taking a squirrel-cage induction motor Y802-2 as an example, 3D fluid-flow and heat-transfer on the medium-small induction motor were researched. Considering the ventilation structure and characteristics of heat-transfer of the motor, the outer approximate infinite fluid field and 3D finite-element structure models of the motor were established, including thin rotating fluid domain on rotor surface and moving fluid domain of fan in surrounding fluid field of the motor. Based on some corresponding boundary conditions and assumptions, fluid motion equations and energy equations were solved by using finite volume method (FVM) to obtain motion state of fluid medium and heat transfer coefficients of each surface of the motor which were foundations for calculating thermal field. Temperature distribution based on coupling calculation and obtained the temperature results by traditional method compared with the experimental values, which proves that 3D fluid field and thermal field of medium-small induction motor have strong coupling connection, and the temperature results based on fluid motion are more accurate and reasonable. © 2017, Harbin University of Science and Technology Publication.
