- Winding pattern of the simulated machine under Manatee
Results and comparison
The weight measured on the real stator is favorably compared as the simulated one as shown on the following table.
| Stator lamination mass [kg] | Stator winding mass [kg] | Overall [kg] | |
|---|---|---|---|
| Numeric | 0.787 | 0.633 | 1.420 |
| Measured | 1.426 |
Analytical natural frequencies are calculated under Manatee and compared with the experimental ones.
