Instructables

Step 5: ASSEMBLY

1. Place the motor on top of the square tubing and bolt it in, using the two 5/16" x 1 3/4" bolts.
2. Place the diode on the square tubing, about 2" behind the motor, and screw it into position using the self-tapping metal screw.
3. Connect the black wire coming out of the motor to the positive incoming terminal of the diode (Labeled AC on the positive side).
4. Connect the red wire coming out of the motor to the negative incoming terminal of the diode (Labeled AC on the negative side).
5. Center the tail over the square tubing, at the back end. Clamp your tail onto the side of the square tubing.
6. Using 2 self-tapping screws, screw the tail in place.
7. Place each blade on the hub so that all the holes line up. Using the 1/4" bolts and washers, bolt the blades to the hub. For the inner three holes, use two washers per bolt, one on each side of the blade. For the outer three holes, just use one washer next to the head of the bolt. Tighten.
8. Hold the end of the shaft of the motor (which comes through the hub) firmly with pliers, and turn the hub counterclockwise until it tightens and stops.
9. Screw the nipple tightly into the floor flange using a pipe wrench.
10. Clamp the nipple in a vice so that the floor flange is facing up and level.
11. Place the square tubing (and everything that is on it) on top of the floor flange and move it so that it is perfectly balanced.
12. Through the holes of the floor flange, mark the square tubing at the point of balance.
13. Drill these two holes using a 5/32" drill bit. You will probably have to take off the hub and tail to do this).
14. Attach the square tubing to the floor flange with two sheet metal screws.

For a longer life span of your wind generator, you should paint the blades, motor sleeve, mount and tail.

I have a permanent magnet 2.50 HP heavy duty treadmilll motor. It has a positive wire, a negative wire, and 2 blue wires that come off the positive post. What do I do with the blue wires? Do I have to use the bridge rectifier if I am using a charge controller? Any help would be appreciated.

If this is a dc brushed motor then the coil is the one rotating inside the magnets so it will automatically produce dc, adding a full bridge rectifier will ensure that if the motor spins in reverse it will produce the same polarity but it will decrease the output by 0.5 to1V

In some circles, this 4 diode arrangement trapped in a little cube that takes AC and makes it DC is called a Full Bridge Rectifier. You will have better luck finding one at many electronics stores by that name. Frys Electronics sells them for about 10 bucks in California. Website frys.com

Why 2 washers on some bolts and one washer on others?  I've always believed in using single-coil spring washers (or Nylock nuts) too.
