About Datasheet

I am a mechanical engineering student and I am working on our graduate project with my team. We bought some motors from Pololu Robotics & Electronics, however, we need the datasheet to reach the motor constants to design a controller for our motor. In this context, my team and I will be appreciate if you have a chance to supply the datasheet of the motor, which you can find the link of it below
Thanks for your concern

Have a look at https://www.pololu.com/product/3214/faqs - the datasheet is not available, but there is some information on how to calculate the various specifications and behavior of the motor.
