1 AnswerEngineering6 years ago### How can I rotate 6v dc motor by using Transformer and bridge rectifier?

Dear

I have got a 6v dc motor and that I managed from charger fan. I also have 12v & 9v step down Transformer. I’ve made bridge rectifier by diode 1N4007 properly. Now facing tremendous difficulties. Please have a look in below:

1. As I am taking 240ac as source and 12v or 9v step down Transformer as well, the output should be 12v or 9v ac. The output showing 20v ac or 25v ac.

2. The main difficulty is, after using bridge rectifier, I should get full wave, that is 12v dc or 9v dc and the 6v dc motor should rotate. But it is not happening. I can’t understand where the problem is. The Diode has been connected properly and the Transformer is new.

Appreciate, if you would get back to me with proper solution at your best possible time.
