Abstract
A software package in TURBOC + + have been developed for the determination of steady state temperature of the body and any internal point of the motor structure of small squirrel cage induction motor. For normal motor operation and solid state speed control applications, where the performances are judged by the changes in loss, the steady state temperature rise can be used as a direct indicator of loss rather than measurement as the small difference between input and output power. The software takes the design details of the motor as the input and a mixed parameter (a combination of lumped and distributed) thermal model have been developed based on dimensional information and constant thermal coefficients. The application of the thermal model to a small (2 hp, 415 V, 3-phase) cage rotor induction motor is described here.
