The 12V DC Motor 251RPMw/Encoder is a Gear Motor w/Encoder. It is a powerful 12V motor with a 43.7:1 metal gearbox and an integrated quadrature encoder that provides a resolution of 16 counts per revolution of the motor shaft, which corresponds to 700 counts per revolution of the gearbox's output shaft. These units have a 0.61'' long, 6 mm-diameter D-shaped output shaft. This motor is intended for use at 12V, though the motor can begin rotating at voltages as low as 1V. This motor is an ideal option for mobile robot projects.
Does what it says, and was powerful/quick enough to work for our inverted pendulum project. Thanks!

Good motor
Good motor, but the technical data is wrong. This motor has 64 CPR, which Equals to 2797 Counts per revolution on the output shaft.

Very good motor for the price
We used it for a Robot competition, and got 2'nd Place :-) Plenty of Power for us. Slightly Heavy

Great Motor, counts per revolution wrong
Great motor overall, however the description of the encoder is incorrect, it claims 2797 pulses per revolution on output shaft, however actual output is 700 (derived from experiment and calculation). (16 (pulses) * 43.7 (gear ratio)) = 700 Comment RobotShop: Thank you for your review and for pointing out the correct output, Mack. We corrected the product description.

Good Product
This is a excellent motor, with excelent relation quality/price about motors with encoders. it's not too noisy. Works well
