It's a motor that I want to use in a rc boat, it runs on 12 volts and the current draw in 4A

thanks guys! i solved the problem... I just took out the secondary turns that was 2.5mm cable and replaced it with a 1.5mm cable. works like a dream!

hi does anyone perhaps know what size capacitors are used to block the radio interfierence that a DC motor produces when it runs? its a 12v dc brushed motor thanks

Yes life year there is a rectifier on the secondary side and the given voltage is on the DC side, and it is a full wave rectifier with a 100uf cap

So if I lower the voltage to about 10v it will still be fine to charge a 12v battery? Or should I just put in a voltage regulator to keep the voltage low?

Hi At work I am curntly building a battery charger. I took a 220v to 10v transformer and took out the secondary windings because I wanted to make it a 12v, I rewinded it with 2.5mm flexible cable untill I got my 12v. The transformer works well untill I connect it to the battery, the current...
