These folks sell amps (and SEM motors) and will be able to give you
exactly what you want:

Find your motor in here:

They'll match it to an amp in here:

If I guess right, you'll probably have MTS30R4-42 motors (or something
really close), and you'll probably want the SDFPO1525-17 amps which were
probably the original equipment anyway and the bolt holes will line up
;) .

You'll need a bunch of other stuff too, see this for an example
(although your setup will vary somewhat):
