Paper presented at the SPE Annual Technical Conference and Exhibition, October 16–18, 2023
Paper Number: SPE-215170-MS
..., the situation is not the same in liquid-cooled motors. We focus in this section on heat generation by fluid friction in the annular air gap. Due to the high speed of rotation and small clearance between the stator and rotor, the fluid in the air gap is exposed to high shear stresses and that represents the main...

... clearance. On the other hand, the stiff string model considers the effect of stiffness, thereby accounting for the extra side contact force. In theory, the stiff string model is more accurate because more variables are considered. However, the field data is more inclined to match the soft string model...

.... Another input to the sub-model was the oil shear heat generation. This iterative approach deteremined the maximum motor bearing temperature ( Fig. 6 ) because the heat generation was the function of clearance, and the clearance was the function of the temperature due to thermal growth. The bronze sleeve...
