Depending on the complexity of your test and the required data collection an FPGA could do it. On thing you should do is gather your requirements (data rates, motor charactistics, reporting criteria, desired cost range, etc.) and give a phone call to your NI rep. They are usually pretty good on suggesting options.
To be a small portable solution you are probably looking (like the previous posters said) at a compact RIO based system. Once you get it programed and "set free" as I like to think of it, no computer is necessarily required. You could even use the LEDs on a NI9474 to display go-no go type results.
Hope this helps,
