Hi there, I need your help. I managed to get an Emerson Treadmill Motor Model S67KDE-7656 from scrap yard and wonder if this can be used with Homemade Vertical Windmill Generator Motor? Here are additional motor details:

Pin: KK0064T
Model: S67KDE-7656
1 H.P.
115 Volds
60 HZ 11.6 AMPS
1725 R.P.M. PH1

If it can be used, the battery bank will be Gulf Cart Batteries (2x6) = 12 Volts.

If that is actually the motor from the tread mill, it won't make a generator easily. That plate describes an induction motor, what you need is a permanent magnet motor. I've pulled apart several treadmills and never seen one with an induction motor. The motor you are looking for is 3 to 4 inches in diameter with a heavy flywheel on one end and a pair of brush caps on the other. Most I've seen have a pair of heavy wires leading from the rear.

I tried to contain myself, but I escaped.

Try shorting the connections, compare the resistance to turning the motor's shaft open and short
If it gets very hard to rotate shorted, then you have a candidate

Thanks for your response gentlemen

Mike, I am totally new at this. Please clearify " motors shaft open and short"
How do you do that?

Tks

With no wires connected to each other turn the motor by hand and note the effort required
Now take the two wires and short them out and turn the motor by hand and see if it is much harder to turn, if so you are away

I've seen a few treadmills with induction motors, one model mainly, a cheap one that seams to break down a lot and end up at the tip. It only has a couple of speeds to choose from, where the DC motor treadmills have a more advanced controller.

It does look like that motor is an induction motor, and would be difficult to convert to a windmill. You need to add magnets, and do some machining.

The motor you want will have permanent magnets inside, a couple of brush holders, and be marked as DC.

Hi yyzlxo

I have a treadmill motor for my turbine. Its a DC Motor as the other guys have described - however these motors normally have a very high (for turbine) output RPM. Mine is 4800 RPM to get 230V, so to get 16V needed for charging 12v batteries, I would need to get my turbine turning at 360 rpm. This is a tall order for many home made turbines, mine included.
So, for my two penneth worth, I would stick that motor on e-bay (someone will buy it if strategically advertised!)and look for another permenant magnet DC motor with a low rpm output. Unless you live in a particularly high wind area I would not bother with treadmill motors as generators.
On the plus side, your battery pack sounds OK if you connect them right

Thank you very much Marcus for this information. I wonder if anyone has a spare Motor that they want to get rid off. I will buy that from them or do you know where can get one from? If anyone wants the above Motor for Free let me know because this is of no use for me. Perhaps someone can make use of it.

You are on the right side of the world for an Ametek motor.

The 36V Ametek is meant to be very good, and the bench mark home turbine generator - that is to say before these Ausies came along with their F&P

Do some google searching on the Ametek, then have a look on e-bay, or on your Craigslist or similar.
