The QuickPhase-PC is a complete stepper motor indexer and driver for up to 3 axes. Its space saving design features on board 1 amp bipolar constant current drivers. The QuickPhase-PC inserts directly into any IBM-PC or compatible and requires no external enclosure. Use an external power supply or use one of your computer's disk drive power connectors. Suitable for low to medium speed applications, the QuickPhase-PC is ideal for CAD/CAM modeling, robotic and laboratory research applications.

Several software options are available. Any one software package will operate on its own. (i.e. you do not need one package to run another). The software you choose depends on your application. The software options are as follows: 1)MillMaster Protm or 2)TurnMaster Protm.


  • 8 or 16 bit IBM PC / AT expansion slot
  • DC power supply to power stepper motors
