Which is the best choice an alternator, permanent magnet alternator, or
permanent magnet generator, for a micro-hydro project?
My criteria are cost, best efficiency, maintenance.
I am on a senior project, to develop a piece of lab equipment based on
micro-hydro, to benefit mechanical and electrical engineering students.

I like permanent magnet dc generation, however, take a look at

A closed water system. Water is gonna be in a pressurized water tank. From
the tank to a 2 inch pipe a few feet above the turbine. The water exits the
turbine into a reservoir which is pumped back into the pressurized water
tank. It will take 40 gpm max and 10 - 40 psi. It will be controlled by a
PLC and data will be taken through meters and Labview.
I was trying to find the best solution for power generation hooked to the

Good luck ..
finding that pressurized water tank ..
and the free pumps
Out in the real world.
