I'm designing a Full Bridge for a Brushed DC motor control. My circuit will have a current measurement, so I'll can control the output current, sinked by the motor.
Whit this current control, I think that I could safely overvoltage my motor, using a battery with a higher voltage that the specified to the motor, since I'll never allow the current to overcome the max. current of the motor. With this, I could achieve bigger velocities.
My doubt is if you see another problens, rather the overcurrent, when I do a overvoltage? I could see the insulation of the motor and also the mechanical problems, like the gear, shafts, bearing and etc, these could be overstressed too.
But, eletrically speaking, the limiting factor, since I can limit the current, is the motor insulation, right?
Someone can see other problems?
