Common motor
This type of motor is used in many battery operated tools such as drills, etc. I needed it to power a lead screw on a custom cutting machine that I made. The motor has been working flawlessly.

Not big enough motor
This motor was not a replacement motor for Dewalt drill.It was way under sized and do not even have teeth or gears on a shaft

Not sure if this is going to work.
Item received was not new it appears used. Terminal points have pre-soldered wires snipped off. The packaging was torn open.

Good motor for wide range of projects
Updated review, after a small issue with my order, i was contacted by the seller and they kindly took care of the issue providing a new item... customer service was quick and considerate... would definitely do business with again!

Not as described
The D motor shaft turned to rounding the flat edge thus does not hold the gear solid and spins with any resistance. Guess only option is to try J B Weld to fill in the open spaces, otherwise Amazon has a sale coming up on the 7th

Strong compact variable DC voltage input motor.
I have yet to spin this motor with a different motor to see the output voltage. Just giving this motor as minimal as a Energizer Lithium 9v battery, it performs past most motors ive played with this size. Well made. (Outside cover/sleeve of the motor is loose, slips around. Its pretty much useless)

B&D Matrix 20v motor replacement
Bought this to replace a motor in a black and decker Matrix drill I burnt out. Works great, direct fit.

As Advertised
Motor came as advertised. I had trouble using a power supply with the motor because of inrush current. Wiring in a PWM controller alleviated this. Also running on batteries worked great. Would recommend.

Very good and strong
Really good motor. Used it to convert a 7.2 volt lincoln grease gun to use a 18 volt milwaukee battery. Exactly as described and strong performance. I reccomend.
