Original Press Release:

NEW! Series of High Performance, Low Cost Linear Stepper Stages from H2W Tech

Valencia, CA - High performance, low cost linear stepper motor stages have been introduced by H2W Technologies, Inc. Traveling at speeds up to 80 in/sec. [2 m/sec], with stroke lengths to 144 in. [3.6 m], and acceleration to 1G, these 2 and 4 phase linear steppers are ideal for: Pick-and-place, wire bonding, parts transfer, semiconductor wafer handling, inspection machines, and other robotic applications. Four models offer 2 lbs [9 N], 6 lbs. [27 N], 10 lbs. [45 N] and 20 lbs [89 N] of continuous force. This new series of single axis linear steppers with a low profile highflex, long life ribbon cable also includes the motor, bearings and positioning system with home position, and optional end-of-travel limits integrated into a compact package.

H2W Technologies linear stepper motors are capable of very precise position, velocity and acceleration control when integrated with a microstepping drive and indexer. The resolution of the 2 phase motors is, one full step equals .010 in. [250 microns] and one microstep equals .00004 in. [1 micron], and the resolution of the 4 phase motors is, one full step equals .005 in. [125 microns] and one microstep equals .00002 in. [.5 microns]. Ideal for open loop positioning applications with light payloads; an optional linear encoder can also be integrated to create a closed loop system.

The step and direction signal from a microstepping driver is supplied to a moving, 2 or 4 phase "Forcer" [coil and magnet assembly] via a power cable. The ground "Platen" [track] is hard chrome plated and surfaced for use with roller bearings. Linear steppers can also be custom designed to meet customer specifications and "stages" can be custom sized, drilled, and tapped for easy integrtation into a new or existing application. Factory integrated and fully tested microstepping drivers and indexers are also available.

H2W Technologies, Inc. is dedicated to the design and manufacture of linear and rotary motion products that are used in the motion control industry. The complete line of linear electric motors includes: Single and dual axis linear steppers, DC brush and brushless linear motors, voice coil actuators, and AC induction motors. Also offered is a complete line of ball screw, lead screw and belt driven positioning stages.

Other motion control products include: Limited angle torque motors for compact, limited angular excursion rotary servo applications, 3 phase brushless rotary servo motors with matching digital servo amplifiers and permanent magnet linear brakes for fail-safe, zero power braking for baggage handling and people moving applications as well as amusement park rides.

With over 75 years combined experience in the linear and rotary motion field, the H2W Technologies team of engineers offers the optimal solution to the most demanding motion control, requirements.
