Resumo

GOUWS, Rupert  e  VAN JAARSVELDT, Heino. Impact of thermoelectric cooling modules on the efficiency of a single-phase asynchronous machine. J. energy South. Afr. [online]. 2014, vol.25, n.1, pp. 13-18. ISSN 2413-3051.

In this paper, the authors present the impact of thermoelectric cooling modules (TECMs) on the efficiency of a single-phase asynchronous machine. TECMs are used to lower the stator winding temperature and core temperature of the single-phase asynchronous machine. A similar effect might be possible by operating the asynchronous machine in a controlled lower temperature environment or by using other means of improved controlled cooling. An overview on the materials and method used during the experimental setup of the single-phase asynchronous machine with the TECMs is provided. Experimental results on the efficiency analysis, temperature analysis and equivalent circuit parameter analysis are provided. It is shown that the efficiency of the single-phase asynchronous machine can be increased by 4.44% when cooled by TECMs

Palavras-chave : asynchronous machine; thermoelectric cooling modules; efficiency temperature analysis.
