Abstract
A small generator includes a hydraulic turbine provided in a fluid path rotating with a passage of a fluid in a predetermined flow and a rotator coupled to the hydraulic turbine rotating together with the hydraulic turbine which acts as a rotor portion opposed to a stator portion having multiple layers in a stepping motor including the stator portion, wherein the rotor portion relatively rotates with respect to the stator portion with the passage of the fluid, thereby generating a power.
Claims10
A small generator comprising:
- a hydraulic turbine, provided in a fluid path, rotating by passing a fluid in a predetermined flow rate;
- a rotator, coupled to the hydraulic turbine, rotating together with the hydraulic turbine, the rotator acting as a rotor portion opposed to a stator portion having multiple layers in a stepping motor including the stator portion,
- wherein the rotor portion rotates relatively with respect to the stator portion by with passing the fluid to generate a power.
