    What kind of controller? Is this to replace or a new application.
    Step/dir? Analogue?
    Intelligent drive or PID loop closed back to the controller only?
    AC or BLDC are the norm now and have virtually replaced brushed drives for preference.

    I am guessing you are using something like Mach so need step/dir drives.
    Larken fill the bill especially if using SEM.
    Are you using the existing power supply? If not ideally you need a DC supply that is at least motor voltage +10%.

    For servo's I think I would go with Dynomotion over smooth stepper, you get closer to true closed loop control.
    If you have existing analogue drives already you can add Kanalog for 10vdc control.

    A couple years ago I retrofitted my bridgeport V2E3 mill. I went with dugong drives and have been extremely satisfyied. I used a laptop, mach and a smoothstepper. I am still amazed how well everything performs. I did a build thread on cnczone, just search for V2E3 and you can look it over.

    I am now retrofitting my 14x40 geared head lathe and went with the smaller brother to the dugongs, the whale3 and kelling servos.

    Hope this helps some
