The sub-system consists of a direct drive ServoTube actuator, driven by the company's high-power density Micro Xenus controller. Actuator and controller create an out-of-the-box drop-in replacement for ballscrew and pneumatic positioners, yielding controllability, agility, and faster machine cycle times. Matched positioning pair develops velocity to 2.8 m/sec and peak drive force to 87 lb. Actuator requires no external encoder for position feedback. ServoTube's patented magnetic circuit enables an integral solid state sensor to provide 12-micron repeatability.
