Totally new to this guys, so sorry if my question are dumb. Anyways I have a small 3v motor I want to turn at max speed/torque whenever it is turned on. I am using a 8.4v power supply to power the motor. This is controlled by a 5v pulse that turns on a MOSFET which allows power to the motor. The power supply is 6 AA's so they slowly will reduce in voltage. So what I want to know is should I use a LM317T voltage regulator and regulate it at 3V or just simply put in a resistor to controll the voltage to 3V and not worry about the batteries slowly becoming weaker.? I measured the motor and it measurs 1Ω so it would be a fairly small resistor. I'm trying to keep this small but I do want peak performance, so any input would be much appreciated.
On a side note, what kind of difference would I see from a 6v motor? Thanks for any help. Also the load on the motor will be fairly constant.
