I mean, I guess it was a price, such as more batteries gave out already 15tl much yield did not expect occasional uses, but a permanent solution to the problem is to use sıklaşınca, I decided to run with the same transformer can be used in the system the Cordless screwdriver.

I get more torque and acceleration to a higher voltage transformer used with 7 .2V AC output I got this output is not reducing the secondary transformer 100w giving him unwrap his bandage after I added a 7 .2V level brought the diode bridge output I got 3 for TO220 case not fast diode 6a diode used (see; Schema) 7.2 v mains after about 6.4 v was exactly what I wanted, I’m using speed, power was smoothly.

Simple schema.
