Drill Torque Loss Answered
I am having some trouble with torque loss from a drill motor and gearbox I harvested for a project. I followed the steps in this instructable (https://www.instructables.com/id/Hacking-Drills-CheapPowerful-GearboxMotors-for-/) to get the motor and gearbox. I then hooked it up to a motorshield and an arduino.
Originally the drill (Rigid 18v Cordless) States that it can deliver close to 500 lb-in of torque. However when I hook it up to my apparatus I am able to stop the spinning with my hand.
I use PWM to control the speed but upping the speed still does not produce the required torque.
If anyone has any ideas as to why it dropped in torque I would be very appreciative.
Thank you in advanced.
