Abstract
A rotary electric machine and a turbine system including a housing, and a hydrogen generator arranged into or on the housing. The hydrogen generator electrolytically generates hydrogen from water. The hydrogen generator supplies the hydrogen into the housing.
Claims4
1:
- A rotary electric machine comprising:
- a housing enclosing a rotor and a stator;
- and
- a hydrogen generator arranged into or on the housing, which is configured to electrolytically generate hydrogen from water;
- wherein the generated hydrogen is supplied to the rotor and the stator to be cooled.
2 more elements
2:
- The rotary electric machine according to claim 1, the hydrogen generator further comprising:
- a pressure detector configured to detect internal pressure in the housing;
- a flow detector configured to detect water flow to the hydrogen generator;
- and
- a regulator configured to regulate at least one of gas flow or pressure of the generated hydrogen in accordance with the internal pressure.
2 more elements
3:
- A turbine system comprising:
- a turbine comprising a turbine rotor;
- and
- the rotary electric machine as in claim 1, wherein the rotor is rotatably coupled to the turbine rotor.
1 more element
4:
- A turbine system comprising:
- a turbine comprising a turbine rotor;
- and
- the rotary electric machine as in claim 2, wherein the rotor is rotatably coupled to the turbine rotor.
