I am fixing a robot and we are using a 12 volt air compressor (off of one of those car tire inflator things that plug into the cigarette lighter).
The compressor runs fine to build up the tank pressure when first turned on, then when operating the pneumatics, if the pressure is > 30PSI the motor WILL NOT spin, it exhibs a current of 12 amps, and does not rotate. The normal current rating for the motor is around 9 amps operating.
Is there a circuit I can build like with a capacitor maybe to increase the voltage to the motor to get it spinning under the load?
Or does anybody have any suggestions?
I was thinking of actually oscillating the voltage like with PWM, or making a voltage doubler? But wouldn't that cut the current too much? It can't go below 9 amps
Thanks!
