The present invention relates to a generation unit for small hydropower generation capable of promoting an economical gain by increasing generation efficiency by achieving an increase in the number of rotation, caused by a magnetic force, and a rotation of a plurality of stators using a rotational force applied to an input shaft. The generation unit for small hydropower generation comprises: an input shaft to which a rotational force is applied; a rotation means connected to the input shaft to rotate a magnet by the applied rotation force; and a generation means generating electric energy according to a change in a magnetic force of the magnet rotated by the rotation means. The rotation means includes a first rotator to which the input shaft is axially fixed and which has a first magnet formed on a surface thereof; and a plurality of second rotators positioned between the first rotator and the generation means, radially arranged with respect to the input shaft at regular intervals, and having a second magnet to rotate to correspond to the magnetic force of the first magnet.;COPYRIGHT KIPO 2015
