Evaluation, Categorization, Distribution and Methods of Reduction of Losses to Improve Thermal Design of SCIM Motor

摘要

For any thermal design and improvements of the motor accurate evaluation of the losses and reasons for existence of these losses because of which they occur is very important. Experimental techniques aiming at determining total losses and temperature rise in squirrel cage induction motors (SCIM) are expensive and their effectiveness is often limited to specific types of motors. Accurate estimation of these losses and how they are distributed along with feasible techniques to reduce them will result a scope to optimize the thermal design of the motor. In the present report evaluation, categorization, distribution and methods of reduction of all losses in SCIM Motor are presented. This has been done with relevant mathematical expressions and presenting properties of important materials.
