Can't answer that without knowing more about the motors and the drives.
They are probably DC Brushed motors and It's quite possible you can get away without drives but it will probably require a different controller that uses +/-10V analog signals and these get expensive quick and are not so popular as Step/Dir controllers. You can get DC Brushed drives which accept Step/Dir signals but they are often not cheap.
It's often cheaper and better to just replace them as a set with modern AC motors and use a Step/Dir controller.
