MotorThe ANT130-L direct-drive linear-stage motor offers long travel, smooth, cog-free motion and nanometer accuracy, the co. states. The motor employs a center-driven, noncogging, noncontact linear motor and encoder as the driving element. Because the linear motor is a direct-drive device, there’s no backlash, windup or “stiction,” the co. says. The linear motor drive also offers the advantage of higher speeds and accelerations as it reaches a peak unloaded acceleration of 1 g and a maximum velocity of 350 mm/sec.
