I was buying dc motors for making robots. I wanted to ask whether the voltage written on the motor eg. 12v or 24v matters. Whether a 100RPM 5kg/cm torque 12v dc motor is any different from a 100RPM 5kg/cm torque 24v dc motor. If i give 24v to a 12v motor, then would it be a problem, or would it not accommodate 24v and finally perform as it would have performed on a 12v power supply? Or a 12v motor would perform better on 24v than it does on 12v?
