HectorNow it is my turn to speak of what I have done in the past.In 1991 I mounted one of these tandem rotored, Indiana General motors from the main stays'l halyard of my schooner, where I was able to get, by switching a double pole double throw switch either series, depending on wind strength, or parallel. I used a hand carved cedar two blade propeller 5' in diameter, made from a 2x4. It was only used at anchor.I found it more useful, when under sail, to put one, belted off my engine propeller shaft, which turns at any speed over two knots under sail, anyway.It supplies all my modest electrical needs on long sea passages, including, refrigerator(12v), radar, HF SSB, lights, and navigation gear, as well as keeping the six, six volt, golf cart batteries totally at full charge.There is no sense of drag, but then, it is a 33 ton vessel, with five sails on two masts. The auxillary engine is an 85 hp John Deere diesel. It can go faster under sail, than with the engine, (to give a sense of hp from the wind.)These dc generators are nothing special, except they have a lot of windings and two commutators, and charge batteries at low rpm.I have three of these motors including the one in the boat.They cost $10 each at a surplus store in Toronto.I posted all about them on this forum years ago.Only now, you are telling me it can be looped?How would you do that? They produce Lenz's law drag like any other permanent magnet dc motor!I did use a couple, in Kone's idea of the dc rectifier daisy chain, series of ten big dc motors experiment I did.Although it wasn't looped, I sure think it could be, from my results.I need to repeat that experiment, recording everything carefully, now I have a scope.So Hector, how would you use this type of dc motor to loop?Cheers WarrenSent from Yahoo Mail on Android

be known that with a 10 to 1 ratio this can be looped ! 12,24 or 48 volts DC !
amen !
want to go cheaper ? try this

some 47 watts were used to produce over 75 W !
