Or a drill that wanted to perform better?
Or any motor that has a load.
Here is the solution its my dc motor mod.
It gives the motor more torque and conserves energy using capacitors to collect magnetic energy while its spinning.
It also limits the amount of current used when the motor is under load.
Through out the instructable i'll show you how
Step 1: What U'll need
A dc motor
A small flat head screw driver
A soldering iron
A desoldering pump
Some SMD ceramic capacitors (about 100nf -330nf non polaried)
(the amount of capactor depends on your motor)
