I am doing some research before I start my project. I will not be building a generator but will be taking advantage of current technology.
Using DC motors to generate electricity requires inverters to convert to AC and to make a AC sinewave however the cheaper inverters do not create a true sinewaves so you cannot inject this AC directly into your DB board unless you buy a very expensive inverter which can range from R3000 up to R15000 and more
Using a car alternator you can produce a pure sinewave which theoreticaly can be injected directly into your DB board however the rpm's required to use an alternator is extreamly high from what I have read.
Now my questions
1 What is better? A DC motor or an AC motor. " I believe that DC would be better.
2 What are the best ? DC motors to use eg, wheel chair motor,
3 What are the best ? ACmotors to use eg, weed eater motor, car alternater
As children growing up we had little cars with a weighted balanced wheel. rubbing the cards wheels would generate energy in this wheel and when you put the car on the ground it would drive for some distance before stopping.
Can we not apply this theory to the wind turbine? I know that it would make it difficult for the wind to start it up however would it not assist the turbine in keeping a constant speed under low wind conditions. Just an idea. What do you guys think
