I was buying dcDC motors for making robots. I wanted to ask whether the voltage written on the motor eg, e. 12vg. 12V or 24v24V, matters. Whether a 100RPM100 RPM 5kg/cm torque 12v dc12V DC motor is any different from a 100RPM100 RPM 5kg/cm torque 24v dc24V DC motor. If iI give 24v24V to a 12v12V motor, then would it be a problem, or would it not accommodate 24v24V and finally perform as it would have performed on a 12v12V power supply? Or would a 12v12V motor would perform better on 24v24V than it does on 12v12V?
