It's a sooooper high precision (2540 cycles/turn) encoder.
It's got a 1/4" shaft with a flat on it, so it doesn't really meet your motor's requirements, but if we could figure out a way to connect it, it may work. 
Does the motor have a shaft out the back?

Why don't you guys use the flywheel and a reluctance sensor as an encoder? That would cut a significant portion of the costs.
The input capture peripheral and a free running timer can be used to measure the time between each pulse
