The axial flow hydroelectric generator is composed of a water turbine and a generator coaxial. The water turbine is mainly composed of water blades, guide covers, bearings, water seals, main shafts, etc.  The axial flow hydroelectric generator mainly uses the corresponding height of the draft tube to form a vacuum suction pipe, which pulls the incoming water from the upstream through the vortex chamber to form a vortex. The jet water blades rotate at high speed and drive the generator to work through the main shaft.

The three stator windings of generators below 0.6kw are connected in a triangular manner, and the rotor is made of permanent magnet material.

The stator winding of generators above 0.6kw (including 0.6) adopts the method of measuring shape connection, and the rotor is made of permanent magnet material.

Way of working
Axial flow small hydro-generators are mainly used in places where water flow drop is relatively low, such as small rivers and small creek.
The axial flow small hydro generator is mainly composed of a generator and an impeller coaxial.
 

Working principle and installation method:
 
First, plan the installation site, generally next to it, or where there are rocks underneath. Use concrete and stone to build the inlet channel; use a wooden board to make a switch sluice; use a wire mesh to make a garbage baffle to form the water inlet system.
 
Use a concrete and stone to build a spiral flat channel according to the model, so that the water forms a vortex and drives the impeller to rotate.
 
Under the spiral plane, a small, large, horn-shaped draft tube is built, which is mainly used to make the water form a suction force inside, and attract the impeller downward, thereby generating strong power to drive the generator.
 
Therefore, the power of the generator is mainly from the draft tube, and the length of the draft tube is the drop of the water flow, called the water head. Small axial flow hydro generators generally work between 1 and 6 meters of water head.
