motor as generator
motor as generator
(OP)
Hello,
I am designing an inexpensive water current turbine. This hydro installation only use the water speed of water to generate electricity.
As I already have 3 phase motors (1.5kW, 2850 RPM, 220/380-420V), I was wondering if I can convert them into generators for the turbine. These generators are expected to produce electricity for various speed. Is it possible? How can I do that?

RE: motor as generator
If you do not have access to the grid then this type of motors can't be used, you need synchronous motors (gen.) and some kind of speed governor and exciter, there are other considerations such as electrical and mechanical protection for the equipment etc.
There is a site you can check http://microhydropower.net

This type of machine produces only real power, the reactive power required to generate the magnetic field is provided by the utility. The frequency is controlled by the utility power too.
