# ALG_002

### Objective

Topology Squirrel Cage Induction Machine (SCIM) Analytical electromagnetic model EM1.SCIMAnalytical structural model SM1Analytical acoustic model AC1 Maximum sound power level during run-up (SWL) NA NA

This validation case compares two skewing models: the one consisting in calculating the average flux to calculate Maxwell tensor, and the one calculating average radial tensor from the 3D field calculation.

### Machine

Manatee model for SCIM_011

### Results

Comparing skew method: average flux vs full 3D flux

Due to the specificity of dominant magnetic force harmonics in induction machines, the two models are equivalent. The skew model Input.Simu.type_skew=1 should therefore be used as it less memory consuming.
