For start I think you don' t need it because first you will want to run AC motor simple open loop V/Hz method then sensorless Vector control and only then closed loop with sensor (a lot great fun of PID tunning). Not much hardware difference just you have or you don't sensor
It is standard quadrature incremental encoder 500 lines per revolution, 5V supply can be found here:
US Digital | Products » E5 Optical Kit Encoder
Here others from Farnell:
Farnell Export
Yes they are expensive and must search hard to find cheap one
