MINIATURE HYDROELECTRIC STATION Russian patent published in 2016 - IPC F03B13/10 

FIELD: power engineering.

SUBSTANCE: claimed miniature electric power station with the hydraulic turbine horizontal axis integrated the electric generator arranged in the single basic housing. It incorporates the stator, rotor, output waterproof cable and vaned hydraulic turbine articulated with the rotor via step-up gearing. Said turbine includes the wheel 31, vanes 32, feed chamber, cowl, stator and straightener blades. Said electric generator represents the reversible design. The stator is shaped to the sleeve 9 accommodating the laminated core 10 with winding 11 and fitted on the stator fixed shaft 13 rigidly connected with the basic body. The rotor is shaped to the ring 23 with permanent magnets 24 arranged in its inner surface around said core 10 to make the radial working clearance and rigidly secured from both side to the rotor bearing discs 25, 26 resting via the bearings on the shaft 13. Hence, the rotor hollow body is composed to house the core 10 with winding 11.

EFFECT: decreased overall dimensions and material input, higher reliability and power output per unit weight, longer life.
