Hello everyone! I am new here and I did go through a lot of posts trying to find the answer but couldn't find the specifics for what I am trying to do. I have a small horizontal axis water turbine and I am using a micro PMDC motor as a generator (this is all for experimental purposes so the conversion efficiency from kinetic energy of water to the electrical energy is not very important). Now, at around 500 RPM (I have two blades attached to the shaft of the motor/generator) I am reading 0.45V. All I am trying to do is to electrically control the RPM of the motor, nothing else. So what I did, I added a zero ohms resistor across the motor hoping that the huge load will slow down the generator however that didn't work. Apparently the torque on the shaft from water energy is high enough so that I can't really load the generator enough to cause the RPM change. Any ideas on how I might be able to do this? Also, I need to keep the flow rate of the flow constant so I can't alter the RPM that way.
Thanks,
Thanks,
