Yes, the resistance I was referring to is the permanent magnet passing the poles. The prop I was using simply didn't have enough torque to get it spinning with the wind speed I have available in this particular application. That wind is a fixed speed and never changes so I either have to work...
Rotor aside, I am still stuck with how to identify a motor with a low torque start-up requirement. I have a continuous, but slow wind speed to work with, and low power requirements. Seems like there should be plenty of kinetic energy available, but how to convert it to electricity is the...
In this case the ability to place the turbine blade horizontally and be able to elongate it for more blade surface area if needed seemed like a good option because of the small space in which it will operate. A traditional prop style blade doesn't fit the space available very well, but it sounds...
Well, it does seem to work better than the alternatives I have tried so far. I plan to explore a hybrid design combining the savonius (to get it rotating at all) and perhaps a darrieus style in one rotor (to help it gain RPM once it's spinning at all). I my abandon all of those options and go...
Hello,
I am not sure if this is the correct forum. I was torn between Electrical Engineering and Mechanical Engineering and I thought I would start here.
I have been kicking around an idea for a DIY project and realizing I don't know enough about DC motors to find the parts I need. In this use...
