32V Motor - Any use for it?
« on: June 01, 2014, 06:54:10 PM »
Does anyone think an old 32-Volt DC motor would be of interest in a DIY project?

There's a member on a different forum asking for any takers of a 32 volt, 30 Amp (1HP) DC motor.  It made me wonder if anybody on Fieldlines is looking for 32V equipment to restore or fit into an old 32V system they may have.  I have no association with the other member, except being a long-time member of that forum, like him.

I've already determined that it won't work very well for a wind turbine, because it weighs 140 pounds, and its rated power is at 1250 RPM, so de-rating it to be a 12V generator would leave it somewhere around 400 RPM, but at that would only provide about 20-30 amps.  I don't think anybody would want to hoist up that much weight for 300 Watts.

Would it be of any use in, say a hydro outfit, to charge a 24V battery bank?  A medium-head, medium flow water plant would probably want to run at about 1200-1300 RPM, like this motor, wouldn't it?

Anyone who wants to know more can look at these pictures:

...and read the posting on this forum:  http://www.eng-tips.com/viewthread.cfm?qid=365646

The person posting about it is in California.  The motor has a sticker with a Nevada address on it.
No one believes the theory except the one who developed it.  Everyone believes the experiment except the one who ran it.

System spec: 135w BP multicrystalline panels, regulated by Xantrex C40, DIY 8ft diameter wind turbine, regulated by Tri-Star TS60, 800AH x 24V AGM Battery, Xantrex SW4024

Small electric cart motor? Heavy for that even though
