Its Power Loss by using Lumped-Circuit Model

Y. Oner. Thermal Analysis of the Three-Phase Induction Motor and Calculation of Its Power Loss by using Lumped-Circuit Model // Electronics and Electrical Engineering.- Kaunas: Technologija, 2010.- No. 8(104). - P. 81-84.One of the most important factors to be considered in the design of a motor is the thermal structure of the motor. That is, pre-calculation of the thermal temperatures to be experienced by the parts of the motor while working should be performed and hence, appropriate materials should be selected. There are two main approaches to these calculations. These are analytic Lumped circuit model and numerical analysis. The purpose of the present study is to draw out the Lumped circuit model of three -phase induction motor and calculation of the thermal values for its parts by employing Motor cad program package.
