Here I am showing you how to use the back of a car alternator to charge control your battery bank. I am just using the back of the alternator because that's the only part we need. I use a low rpm river turbine to give it the 3 phase power. I am not using it at the moment because I run a hybrid hydro and solar charge controller for charging the workshop but I will definitely be using this on a remote site to give 240v where needed . Like share and follow for more interesting builds from already a

This is another video that got over 1 million plays. It shows the outside charging cabinet using the back of a car alternator to charge a battery from a washing machine motor mounted on a bicycle mounted on a air handling fan. I have the blades on the fan closed off to make buckets. I generate in 3 phase ac at 2 amps per phase. The voltage on the Ac side will be from 11.5 to 13v ac. The alternator part turns this to a charging DC voltage. All voltage readings depend on state of battery at the ti

Looking at the difference between a car alternator and the permanent magnet motor we use as a generator. In the alternator it doesn't have a permanent magnet rotor instead it has a coil that is energised causing a n electro magnet. The alternator has to be spinning over 800rpm to get 15v dc and that's why I don't simply use a car alternator. There are a few things we can do to to make it work better and one of these is to fit some permanent magnets on the inside and this should give us a very ef
