This is not a design module for generators or transformers. It is a practical approach to get a generator with reasonable efficiency and mass.
The values in all textboxes may be modified. The module will display warnings if values are outside certain criteria.
Runner inertia (Rnr. MD2) is automatically calculated by the Turbine designer.

Generator efficiency in a diagram. Loss parameters and dimension mode variables.
