Abstract (AI)
The paper introduces a practical (analytical) nonlinear (iterative) main field model (AIM) directly attachable to the three phase induction motor industrial design tools. The two dimensional model divides the motor cross section into five circular domains. The slotting domains are homogenized and characteristic magnetic permeabilities for each domain are defined. The calculated magnetization characteristic and, respectively, core losses are fully validated by tests on no load and on load for a batch of induction motors from 0.7 kW to 45 kW.
Key Findings
1
Calculates magnetization characteristics and core losses using the AIM and validates them against tests under no-load and on-load conditions.
2
Defines characteristic magnetic permeabilities for each domain to capture slotting and material effects.
3
Introduces an analytical nonlinear iterative main field model (AIM) that can be directly attached to three-phase induction motor industrial design tools.
4
Model represents the motor cross section in two dimensions divided into five circular domains with homogenized slotting regions.
5
Validation performed on a batch of induction motors ranging from 0.7 kW to 45 kW, showing full agreement with experimental tests.
