The first Hungarian water turbine was designed by the engineers of the Ganz Works in 1866; industrial-scale production with dynamo generators started only in 1883.
[4] Turbo generators were also used on steam locomotives as a power source for coach lighting and water pumps for heating systems.
Turbo generators are used for high shaft rotational speeds, typical of steam and gas turbines.
Heavy non-magnetic metal wedges on top of the slots hold the field windings against centrifugal forces.
The absence of oxygen in the atmosphere within significantly reduces the damage of the windings' insulation by eventual corona discharges.
