NEW AMERICAN BOCSH ½ HP 12-120V 640 WATT DC MOTOR/WIND GENERATORALL MOTORS ARE TESTED ON A DC VARIABLE SPEED CONTROL BEFORE SHIPMENT. GUARANTEED TO ARRIVE IN WORKING CONDITION AND BRAND NEW. I have geared this auction for people who want to use/experiment with this motor/generator as a wind generator. For this reason, I am including the following items in this auction (Photo #1 shows everything you get in this auction.) 1. A 40 amp, 100 volt stud blocking diode. An absolute necessity for your wind generator set-up. What does it do? This diode will allow electricity to flow from your wind generator to your battery bank, allowing your windmill to charge your battery bank. It will NOT allow electricity to flow from your battery bank to your wind generator. If this happens, electricity would go to the motor on the windmill from the battery bank and spin the motor when there is no wind. The motor would spin until the battery bank was completely drained (very bad). Do not settle for a small diode. It will "leak" electricity to the motor. The one I am offering is more than sufficient for this set-up. Look around on ebay and you will see that a 40 amp, 100 volt stud diode will cost you about 8-12 dollars with shipping. After your purchase and upon request, I will e-mail you clear instructions on how to set up the diode (i.e. which end connects to the generator and which end connects to the battery). 2. A heatsink to mount the diode on. To operate efficiently and to keep it from breaking, the diode can not overheat. This heatsink will work for the motor/generator in this auction. If at some later time you choose to use this diode on a larger generator, you will need a larger heatsink. 3. A left hand threaded nut for the motor/generator shaft (see photo #1). You can use this nut to mount a hub. I have saved you the trouble of trying to track down a left hand threaded nut....as you probably know, every nut you will find in your local hardware store is right hand threaded. 4. I have painted the motor/generator with white, industrial strength, epoxy. The white help keeps the generator cool as these things can get hot when spinning fast. Additionally, it protects the motor/generator from the outdoor elements (i.e. prevents rusting of the metal). If you would like your motor NOT painted, that is fine. Just send me a message when you pay. If you purchase all this stuff separately, it will cost you.Also, I have a lot more technical information on this motor : (1) A torque vs. rpm chart, (2) A amps vs torques chart, and (3) A schematic diagram of how to wire this up. So send me a message if you want me to send you this data. Here is the information on the motor/generator: High quality, heavy duty bronze sleeve bearings. Face mount with two 1/4" diameter, 4-5/8" long bolts on 2.53" centers through the length of the motor housing. The end of the shaft is threaded 5/16"-18 x 5/16" long left hand thread. See photos to get a very clear idea about the size and shape of the motor. There are multiple ways that you can mount to the shaft (see photos). It is a high quality motor that will run strong at continuous duty. This is a brand new American Bosh 640 watt DC Motor/Generator.This generator will produce 12V at 1,000 RPM. 24V at 2000 RPM. Perfect for small scale wind generation. At 10,000 RPM you will get approximately 120 volts DC and 1/2 horsepower. This motor/generator will produce ½ HP at 120 volts as a motor. SPECIFICATIONS12/120 VDC10,000 RPM @ 120 VDC5.5 AmpsReversible rotationCont. dutyShaft 12mm dia. x 2-3/4" w/ two flats & threaded end50 in.-oz. torqueSize 3" O.D. x 7-1/4 If you have any questions, send me a message through ebay. Thanks.The red dotted line in photo #2 does not show up very well after uploading onto ebay. It shows the diameter of the motor housing which is 3 inches.
