Abstract
The 3ɸ - Squirrel Cage Induction Motor (SCIM) used in industrial are prone to thermal breakdown due to its working conditions. Losses in the motor cause rise in temperature. Losses estimation of the 3ɸ - SCIM play a very important role in analyzing the electrical and thermal performances. In this paper a Lumped Parameter Thermal Model (LPTM) and Finite Element Method (FEM) is used to estimate the temperature rise in 3ɸ - SCIM. The temperature rise is obtained considering loss, with load variation between no-load to full load conditions, this enables to analyse the application of induction motor in mines. In addition to that a comparative analysis is carried out between Lumped Parameter Thermal Model (LPTM) and Finite Element Method (FEM) to determine the effective method to estimate temperature rise and determine the relative percentage error in temperature rise at various elements of 3ɸ - SCIM.
