DC MOTORS AND GENERATORS

WHAT IS DC MOTOR?

A DC motor is an electric motor that runs on direct current (DC) electricity. DC motors were used to run machinery, often eliminating the need for a local steam engine or internal combustion engine. DC motors can operate directly from rechargeable batteries, providing the motive power for the first electric vehicles.

DC MOTOR AS A GENERATOR....

-YOU CAN USE A DC MOTOR AS A FREE VOLTAGE GENERATOR BECAUSE DC MOTOR CONSISTS OF PERMANENT MAGNETS,COPPER WIRE AND A CONDUCTOR TO ROTATE INSIDE MAGNETIC FIELD TO GENERATE FREE ELECTRICITY....

-DC MOTORS IN WIND TURBINES

USE A DC MOTOR(permanent magnet motor)IN A WIND TURBINE TO GENERATE FREE ELECTRICITY WITH FLOW OF AIR.IF THE FLOW OF AIR IS VERY SPEEDY YOU CAN GET HIGHER VOLTAGE.


*** 1-Tower – get your wind turbine up high and into clear wind. The higher the better. Expect a good tower to cost as much to make as the rest of the wind turbine – half of the total cost.

2-DC Motor – very important to pick a motor that produces useful power at LOW RPMs. Do not buy a motor that only produces the voltage you need at rates of 1000 RPM or higher. If you look at eBay you will see lots of motors for sale “for wind generators”, that WILL NOT WORK. They often need RPM rates that you will never get from your wind turbine. With a homemade generator, you get useful power at 150-250 RPM. Be very careful on your DC Motor selection.

3-Blades – size depends on the motor selected. Larger is not always better. A wind turbine with 2 blades will turn faster than a turbine with 6 blades. A wind turbine with 6 blades has more power to turn a larger motor.

4-Vane – points your turbine into the wind.

5-Electronics – an inline diode to stop your turbine from draining your batteries when there is no wind. Rectifier or controller to charge the batteries. And a Kill Switch.

6-Diversion Load – to consume the extra power produced when the batteries are fully charged.
