Hi - can someone please help me with the following - I am mechanically minded not elecrically so please do not pick on me - I purchased a DC motor and gearbox (worm and wheel) from ebay (item 3858047682 if you want to look at it) - now it is supposed to work at up to 20 volts DC - now I was going to use a standard 4 amp 12 volt car battery charger to power it - what I do not know is -
(1) if I used a 20 volt charger instead would it make the motor more powerfull as regards torque or just make the motor spin quicker thus making the gearbox output shaft spin quicker -
(2) as I do not particularly want the output shaft turning faster would using a 12 volt 12 amp rather than a 4 amp battery charger produce more torque or would this not be of any benefit.
I know I can increase the torque by feeding the output shaft into another gearbox or pair of pulleys to increase it but this is going to take up more room than I want to in the unit
Thanking you in anticipation of your help - legin
