Research in Life Extension of Electrical Motors by Controlling the Impact of the Environment through Employing Peltier Effect

This paper explores the application of thermoelectric cooler/heater (TEC) modules (Peltier heat pumps devices) to control core and winding temperatures, aiming reduce effects thermal cycling moisture issues that affect life electrical machines. Electrical windings in a motor will fail for variety reasons, major contributor adverse motor’s is humidity. Due cycling, air containing drawn into through access points such as terminal boxes, bearings, end covers mounting systems. Even spare or replacement motors specially stored heated equipment stores suffer from ingress because normal daily temperature changes. The better machine can be kept warm, less it affected by mechanical stresses temperatures. A series experiments were conducted, whereby TEC was attached section set up pump segment. properties material capacity temperatures along specific locations over time measured. results this research demonstrate tightly controlled, thus enabling reduction moisture, reducing differences. has positive influence stresses, which result improved insulation reliability.
