GENERATORS FOR SMALL HYDRO
POWER PLANTS

G&Em s.r.o. is a dynamically developing company dedicated to the design and manufacture of electric

rotating machines, specialized in generators for small hydro power stations.

We not only have extensive expertise and technical competences, but we also have many years of
experience in the field. We continue to build on this history in the design of generators and electric
motors with more than 40 years already under our belts. In addition to our own R&D, we cooperate
