Question 1

Can you give examples of the amperage or micro amperage at differnt RPMs?

Accepted Answer

1000 to 2000 rpm while charging a 12 volt battery. When using this generator with our 15" blade it can produce .2 amps in 10 mph winds, .6 amps in 15 mph winds, 1.0 amp in 20 mph winds and 1.25 amps in 25 mph winds.

Question 2

What size is the metal rode 2mm 4mm or what

Accepted Answer

The shaft is 3mm I believe, after many different orders of adapters I ended up having to get one with a 3mm input to 5mm output in order to get something that would fit the shaft.Adapter that works with this unit: https://www.amazon.com/Great-Planes-Collet-Propeller-Adapter/dp/B001BHI490/ref=pd_ybh_mlt_0?_encoding=UTF8&pd_rd_i=B001BHI490&pd_rd_r=0PK8HGDDYK2F73M5G8N8&pd_rd_w=U2aHX&pd_rd_wg=t6PXC&psc=1&refRID=0PK8HGDDYK2F73M5G8N8For a replacement fan blade/Propeller this works well so far and saw 14 volts right off, with the above adapter: https://www.amazon.com/gp/product/B00DCV4VL8/ref=ya_st_dp_summaryyou will need a plastic insert to adapt  for the blade hole for a better/tighter fit on the shaft 5mm end. Lucky I had some that came with other blades I bought & tried. This Propeller does not come with any extra reducer adapters for the center hole.

Question 3

What would you recommend covering the pos/neg leads on the back of the motor? The pictures look like plastic or rubber caps

Accepted Answer

There are many ways of connecting wires to the motor, just as there are many environments in which to use the motor.  I can assume that you have already clipped on a couple of leads and tried the motor, but no matter.  As for environment, it often depends on how close the leads will be to other metal in a cabinet or other enclosure.  They certainly aren't too close to the motor's case or to themselves to be left bare.  Electrician's tape is excellent in many cases.  Silicone rubber can give a more permanent covering and be mechanically thick to protect against minor bumps even.  And many hobby and/or electrical outlets can provide you with shrink-fit tubing to slide over the connection and then heat it with a hair dryer to shrink it for a close fit.  Caution!  If soldering wires onto the terminals, do read how to heat sink the terminal and/or use low temperature solder and as small a source of heat as possible to not transfer much heat beyond the terminal into the motor.  One never knows how delicate the connections are within or how much heat any plastic internally can stand.  The same applies with using a hair dryer to shrink fit insulating tubing.  Use some aluminum foil around the motor (wrapped very loosely) to keep from blowing heat into the motor's housing.  Most hair dryers, and contractor's hot air blowers, get very hot indeed, especially when held really close to the object being heated.
