H2W’s custom gold plated, Voice Coil Linear Positioning Stage (VCS10-023-BS-01-MCS-R) was designed for a laser beam steering application. It has a stroke length of 1.0 in. (25 mm), a continuous force of 2 lbs (8.9 N) and a peak force of 6 lbs (26.7 N) and has a payload capacity of 2 lbs (.91 Kg) and a positioning resolution of 1 micron. It is ideal for short stroke closed loop positioning applications where intricate position, velocity, and acceleration control is necessary. Its compact size (3.75 in. long x 4.375 in. wide x 3.52 in. high) allows it to fit into small spaces. The stage has a very low electrical and mechanical time constant. The low moving mass allows for high accelerations of light payloads. The iron-less core coil assembly has no magnetic attractive force to the stationary magnet assembly, which reduces the load on the bearing system, which increases the life of the bearing. There are no magnetic drag forces (hysteresis), which allows for higher accelerations. These actuators are wound in such a way that no commutation is required for motion to occur. Electrical devices such as Hall Effects are not necessary. The result is a much simpler and more reliable system.

This compact (4.0 in. L x 3.5 in. W x 3.52 in. H), light weight anodized aluminum, moving magnet voice coil linear positioning stage features a stroke length of +/- 0.11 in. from the center of travel home position, and has a payload to 2 lbs. For greater reliability there are no moving cables or wires as the coil assembly and linear encoder head are stationary.

These moving magnet voice coil linear positioning stages can be supplied with a variety of amplifiers and controllers to provide plug-and-play solutions for easy integration into new and existing applications. Other options include: Optical or magnetic linear encoder; ball bearing, cross roller, or air bearing slide; different stroke lengths; higher payloads. Custom designs can be quickly supplied.

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.

H2W 12lbStepper

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.
