A water wheel is always specific for the situation. Gratia Hydro constructs water wheels according specification or the situation. Completely assembled, for home building or everything in between is possible. We also make modular crossflow turbines.
The rotational speed of the water wheel has to be adapted to the generator. For that purpose Gratia Hydro sells industrial gearboxes from SEW Eurodrive. We advise you on the type you need, deliver it, and can do maintanance.
Generators come in different models: asynchronous and synchronous. Permanent magnet are a special type of the synchronous generator. It depends which suits your situation best. Ask your question and we will give you an adequate advise.
Bearings and tranmission are a world on it's own which requires specific knowledge. Also in this field Gratia Hydro gained experience.
The automatic control of a water mill is feasable with the right components.
Gratia Hydro has a large blacksmith's and steel construction workshop available. All neccesary work for new build, reparation and restauration can be done.
