      i wanted to ask you all something .....i have 3- 305 oz-in motors
      @4.5A per phase and 2Vdc ,using a 28 Vdc/12 A power supply,direct
      drive config.. i was thinking about going with an "FET-3" 3 axis
      controller rated up to 15A per phase with proper cooling from
      stepperworld.com (only 135$ compared to gecko's at 114$ each)(are
      the FET-3's any good?).....being that the rated torque of the motors
      are for bipolar parallel, what would the approximate torque drop be
      when hooking them up to a unipolar controller in parallel?? and is
      it going to hurt these motors using this power supply at this
      amperage? the capacitors that i choose will reduce the current to
      the motors or the voltage? or both???

      thanks for your time and answers.

      I certainly have not a clue. Others on the list might, but I would suggest asking the question on:

        They specialise in this stuff.
