Santa Clarita, CA — Choose an easily integrated, low cost, high performance, 2-phase or 4-phase, linear stepper motor from H2W Technologies to improve the performance of an existing motion control system or create a new high speed, high accuracy system. These, compact, industry standard, 12 lb. Linear Steppers (53 N continuous Force, 16 lbs, 71 N peak force) travel at 80 in/sec. [2 m/sec.], with 1 micron [0.00004 in.] resolution, and can operate in any axis. Additionally, these 12 lb. Linear Steppers feature 1G acceleration and are the ideal choice for any of the following: New and existing gantry robots, pick-and-place systems, wire bonders, parts transfer, fiber optic, semiconductor, medical, and other precision robotic applications.
Available with a hard chrome, solid or hollow “platen” (track) in lengths up to 144 inches (3.65 meters), longer travels can be achieved by supplying the platens in sections, the H2W Technologies, industry standard, 12 lb. Linear Stepper is capable of very precise position, velocity and acceleration control when integrated with a microstepping drive and indexer. The resolution of these 2-phase or 4-phase motors is determined by the driver. One full step equals .010 in. [250 microns] and one microstep equals .00004 in. [1 micron]. Ideal for open loop positioning applications with moderate payloads, the “12 lb. Linear Stepper” can also be operated as a brushless linear servo with up to 5 Gs of acceleration and no loss of accuracy.
Capable of generating 12 lbs. [53 N] of continuous force, these single axis linear steppers have a forcer [motor], air bearings, side guide bearings, and platen [track] integrated into a compact, low-profile, package. The forcer connects to a motion control system via flying leads or “D” connector. Multiple forcers can operate on a single platen at the same time. Linear steppers can also be custom designed to meet a particular application’s requirements. Complete motion control packages including and indexer and driver for open loop operation or encoder, motion controller, and driver for closed loop brushless servo motor operation are available from H2W Technologies.

Linear Stepper X-Y Positioning Base

Filed under Linear Stages / Gantries, Linear Stepper Motors
Baldor Electric Company launches a ready-engineered linear stepper X-Y positioning base that is capable of dramatically increasing productivity in a wide range of machinery applications. A novel honeycomb-structured composite material used on the base greatly reduces the cost of applying advanced linear motor technology — to prices starting from $7000 — providing machinery builders with a highly competitive alternative to traditional solutions such as rotary motors and ballscrews or belts.
Designated the HoneyComb Series, Baldor’s new X-Y bases are available in a choice of seven standard sizes with square or rectangular working areas ranging from 375 x 375 to 750 x 1500 mm. This range supports a wide variety of applications in markets including design prototyping, semiconductor fabrication, electronics manufacturing and biomed sample handling.
The new X-Y bases offer very high levels of positioning performance. They are capable of move speeds of up to 1.5 metres/second at resolutions to 2.5 microns and with a repeatability of better than 2 microns. They also offer friction-free mechanics with zero-backlash and no wind-up — for a major performance improvement over traditional mechanical transmission design technologies, as well as maintenance savings.
The base’s moving element, the forcer, floats on an air bearing and integrates two linear stepper motors mounted at right angles to each other to provide X and Y directional thrust. The forcer is available in six sizes and in two- or four-phase configurations, depending on the application’s force and resolution requirements. The maximum static holding force is up to 134 N.
Application versatility is enhanced by the base’s ability to have multiple forcers mounted on the same base with overlapping trajectories if required. A high level of attractive force (up to 1780 N) also means that the base can be applied vertically or face down if the application demands. The base’s composite honeycomb structure simplifies applications like this, as the weight of the positioning system is reduced dramatically, by up to 70% compared with previous Baldor models for instance. Complete base weights with platen and forcer start at less than 10 kg.
The bases are supplied ready to use. All the user needs to supply is power to the forcer, and an air supply to the bearing system.
