Single phase 2 speed blower motor controller
I suspect that the motor is the shaded pole type. If it is, there is only one coil of wire that is connected to power. There is also a short loop of wire that has the ends shorted together. That loop goes around a small section of the steel laminations. The speed is probably changed by applying voltage to either the entire coil for low speed or to only a portion of the coil for high speed. When voltage is applied to both the black and red wires, current flows through only part of the coil. The unused part of the coil is shorted rather than disconnected. It is unused either way. One or two good close-up pictures would help to confirm what you have.

It is likely that the last few characters of the part number identify variations of the motor while the first characters identify the basic design. If you search using fewer characters you might find useful information for a similar motor.
