Improved Electrical Modeling of a Double Canned Induction Motor with Squirrel Cage for Performance Analysis
Résumé
The use of canned motor pumps is one of the most secure ways to pump fluids in nuclear and chemical fields. Their particularity is the fact that two non-magnetic cans are introduced in the air gap for leak-tightness reasons. Therefore, the equivalent circuit of conventional induction motor is no more applicable. In this work, an analytical model that considers the effect of the cans for electrical performance analysis is performed. The input parameters are identified from specific tests and the model is validated by comparison with experimental data.
