Hi all, Does anyone know of, or can anyone point me in the right direction for where to find a small, low rpm generator? RPM can be anywhere in the range of 100-300RPM, and size would be around 50mm long. To put this into context, I am building a small turbine (~300mm diameter), which will rotate within the limits mentioned above. Therefore, I need something that will convert my mechanical energy of around 16 Watts, to electrical energy that I can monitor. The main reason for the low rpm, is that I'd like to avoid the use of a gearbox. I don't have much power to lose. I've looked at some small motor/generators, but they all seem to have very high gearing. Any help would be appreciated! Thanks in advance.
