A Keyang motor is a motor that is included in the OCCRA Kit of Parts. It is a automotive seat motor, is fairly small, is a worm drive motor, and spins sorta fast. If you want to compare it to a FIRST KOP motor, I would have to go somewhere between a window motor (since it is a worm drive) and a RS545 with a BB transmission (like what we used for the suck on the FIRST robot if you recall) for speed, but a bit slower and less powerful. They aren't that powerful, but they have a double-ended squared hole so you can mount a shaft on either side. Thus, you can chain several together to get more torque. We use two on the suck roller on the front. Actually, there are two types of Keyangs: one has a square hole (the kind that we are talking about) and the other has a shaft. The shafted kind is an automotive liftgate motor, and is slower. We use one of those to extend our arm.
