I don't know if this is just for demonstration purposes but I mean what is the point in running a small DC motor off of a battery to run a big DC motor as a generator? Like is this just a show the operation as a simulation? Like maybe you decided to do this cuz it wasn't very windy? Cuz the inherent losses from the battery running that small motor, and then the friction from the belt and the torque conversion to the big motor would be massive it would be more efficient just to run the battery to an inverter and plug everything off of that.
Sr. ingeniero,, los transistores que está usando para la demostración son PNP tip 42 porque fija el cable negativo en el medio de la salida del transformador y el positivo al emisor....no es tip 41 es tip 42.
