Motor stage family with direct drive offers new options
PI
This company expanded its PIMag series of linear motor stages with the V-508, a new series of compact linear-positioning stages with high force three-phase linear motors and crossed roller guides (photo). The V-508 family of linear motor stages is offered with 80-, 170-, and 250-mm travel range. Two motor options are available: ironless for highest resolution and smoothest motion; and iron-core for highest force, acceleration, and velocity up to 1 m/s. Mechanically, the V-508 series features high-load, precision crossed roller bearings with anti-creep cage assist, preventing roller creep, which allows a long lifetime in high-duty cycle industrial applications, together with the zero-wear, non-contact linear motor. Linear motors provide smooth motion, and a high dynamic velocity range along with rapid acceleration, because they provide motion directly without the need of additional mechanical components, such as drive screws and gearboxes that add friction, vibration and noise. They are well-suited for scanning applications or automation tasks where repetitive fast start-stop motion with high precision is required and where reliability and maximum uptime are crucial. In addition to electromagnetic three-phase and voice-coil linear motors, this company also provides several types of electro-ceramic linear motors. — PI, Auburn, Mass.
