How to connect your wind turbine / generator / PMA to charge controller

[leamyelectricinc1]

Car alternators, treadmill motors, ceilig fan motors, lawn mower motors and not good wind turbine mortors. Get a Windy Nation PMA if you want real results.

Any advantage as to where the recifier go's? I would think as close to the batteries as possiable to keep the thick 12v dc cables as short as you can to keep voltage/amp drop to a minimum? The 3, 3phase cables can be as long as you need??

The motor is harder to turn because it is under load when connected to a light bulb. This is normal.

A diode needs to be placed between the motor and the battery. This will allow current to flow from the motor/generator to the battery bank (battery charging). The diode will not allow current to flow from the battery to the motor which will prevent the motor from spinning and draining the battery.

Got another related question. I pulled the perm mag motor from a spare lawn mower. It produces DC no prob so long as it turns. 2 issues i have: First, the motor lit up a 12v brake light directly connected to it but was a lot harder to turn. Why?

..And second, I directly connected a spare car batt to the motor leads and the power from the batt turns the motor. Would a wind charge controller prevent both these issues so i can comfortably proceed to invest time to make my wind generator?

Good question. It will not feedback into the turbine because the 3 phase bridge rectifier (the black thing) has diodes inside of it. Diodes only allow current to flow in one direction. In this case, from the generator to the battery bank.

Won't the battery feedback into the turbine? If not, why not. Thanks.

@Schweizer135 A rectifier allows electrons to flow only one way, so it is accomplishing this task.
