Hey I understand the basic concepts of a dc motor/ alternator and want to know how many turns and such can anyone help I am going to try to make it charge some batteries by wind
well mike is right about making a dc motor or an ac motor/generator is a difficult job, it requires specialization courses like machine design but if you want to do it for jus fun you tmight find it on youtube. btw dc motor and alternator are almost same dc motor/generator has commutator which helps in rectifing the voltage but the large scale, one used in turbine are quite different constructionally hope this helps
An alternator is not a DC motor - it is wound to produce alternating current (thus the name) which is rectified by diodes on the case to make DC. Winding a DC motor/generator is not a simple task requiring multiple segments and a commutator to collect the segments in detail. You would be much better off just buying one, perhaps used, than spending your time trying to build something with reliable bearings and speed.
