Abstract

Disclosed is a waterpower generator. The waterpower generator includes: a housing having a hollow; a stator is provided at an inner circumference of the hollow; a cylindrical rotational body which is provided at the hollow and in which a flow channel is formed on the inside thereof; a bearing which is provided between the rotational body and the housing to support the rotational body; a turbine which is provided on the flow channel and is fixed to the rotational body; and a rotor which is provided at an outer circumference of the rotational body and faces the stator. Accordingly, waterpower generator can enhance generation efficiency and can economically generate electrical power even with a small quantity of water.
