Abstract

This paper deals with the role of the radiation thermal resistances in industrial motors, and describes a test-set useful for the resistance evaluation. The test-set is based on a vacuum chamber and on a numerical acquisition system, and the resistances are obtained by monitoring motor temperatures during a heating test. An analytical model that describes how the radiation resistance depends on the motor temperature is also provided. Experimental results obtained on a TEFC 150 W induction motor are shown and discussed
