Investigation of Discrepancies Between Induction Motor Test Results and Design Simulation

This work investigates discrepancies in parameters and performance between an induction machine design simulation and the produced unit. The squirrel cage motor is explored analytically and in finite element space based on the complete design blueprints and material properties. The built motor is subjected to the DC, no-load, locked-rotor, and load tests. The simulated model is created parametric, according to the manufacturing process and tolerances. Solution space search results indicate that performance and parameters can deviate with minor structural changes. Reliable simulation prior to production can greatly reduce production time and cost, while improving performance and allowing for optimization. The resulting approach will be used as a basis for a manufacturing digital twin in further collaboration.
