Preparing the motor

• 1). Use a screwdriver and socket wrench to open up the outer casing of an electric treadmill and remove the DC motor and gear shaft mechanisms. The DC motor should be labeled with "permanent magnet motor" and have a drive shaft with a gear attached to it, which will form the blade hub for the turbine. De-solder the DC motor from the treadmill's electrical system by using a soldering iron to heat up the joins and a solder wick to absorb the solder.
  
  
• 2). Solder 12-gauge AWG cable to the positive and negative terminals on the DC motor. Heat the wire where it touches the terminals until the soldering iron begins to move into the wires. Add solder until the entire joint is covered. Test the solder using a multimeter set to voltage while slowly turning the gear shaft on the DC motor. Touch the probes on the multimeter to the end of the 12-gauge cable, which should indicate live voltage.
  
  
• 3). Solder the end of the 12-gauge cable to a blocking diode, which ensures that electricity stored in the battery does not travel back through the system to turn the turbine when wind speeds are died down. Solder the blocking diode to the input terminals of a charge controller, which helps to prevent the deep-cycle batteries from becoming overcharged.
  
  
• 4). Use 12-gauge cable to screw into the charge controller's primary and secondary output terminals, which should allow you to screw in the cables with a screwdriver. The secondary outputs should connect to a dump load, which acts as a heat sink for excess electricity produced by the turbine. The primary outputs will connect to battery terminals for the deep cycle batteries. You may need to solder eyelets to the end of the 12-gauge cable from the charge controller. The charge controller should be stored in the same area where your deep cycle batteries are located, making the length for the 12-gauge cable from the primary output only a few feet, depending on your battery bank's storage area and design.
  
  

Connect to batteries

• 1). Connect the batteries into a series circuit configuration. Connecting opposing terminals, use battery cables to connect adjacent batteries, clamping the positive terminal on one battery to the negative terminal on another battery. You should size your battery bank so that it can sustain your basic electricity needs for three days without exceeding a 50% discharge. The battery bank should also be sized so that the voltages for the batteries add up to 120 volts, using 10 12-volt batteries or 5 24-volt batteries as an example. Leave one positive terminal and one negative terminal open on two different batteries.
  
  
• 2). Connect the remaining two battery terminals to a power inverter, which converts the DC (Direct Current) electricity from the batteries to AC (Alternating Current) which is used by a majority of home appliances.
  
  
• 3). Connect an extension cord to the power inverter, followed by a power strip, where appliances can be connected to your RE system.
  
  

Final construction and installation

• 1). Use a tap and dye set to form threaded bolt holes in the gear mechanism on the DC motor's drive shaft. Use a socket wrench to connect Windmax turbine blades (recommended by Other Power) to the DC motor.
  
  
• 2). Enclose the DC motor inside a pair of plastic containers. Glue styrofoam blocks into the corners of the plastic containers so that they absorb some of the vibrations caused by the wind interacting with the turbine system. Plastic containers should be heavy duty, so that they are waterproof and can withstand environmental hazards such as UV, rain and snow.
  
  
• 3). Weld steel brackets onto a TV or Ham radio tower and connect the DC motor to the tower. Raise the tower, and support it according to its specific design, which may call for guy lines or concrete footers.
