What kind of motor is this?

[lobsterboyx]

i found this wheelset at a local electronics surplus store and i had to strike. it was a set, the rear is this motor, and the front is a generator. they are both laced in to 700c deep v track style wheels, i want to build a bike around these wheels but i need to know what kind of controller/power i need to use it efficiently.

I don't use hub motors.
