Three-dimensional fluid field and thermal field research of squirrel-cage induction motors operating in broken bar fault
Taking a squirrel-cage induction motor Y802-2 as an example, 3D fluid field and thermal field of the motor operating in normal and broken bar fault conditions are researched in this paper. Considering the ventilation structure and heat transfer characteristics of the motor, the inner and outer fluid space and 3D finite element structure model of the motor operating in the healthy state, one broken bar fault and two adjacent broken bars fault state are built. The rotating fluid field and thermal field of motor operating in above three different cases were solved by using multiple reference frame (MRF) model. Then the influence of the broken bar number on the motor fluid field and thermal field is analyzed, and the accuracy of the model is validated through comparing calculation results with experimental data.
