Linear Stepper Motors

A new series of low cost, high performance linear stepper motors has been introduced by H2W Technologies, Inc. Traveling at speeds up to 80 in/sec. [2 m/sec], with strokes to 144 in. [3.6 m], and acceleration to 1G, these 2 and 4 phase linear steppers are ideal for: Pick-and-place, wire bonder, parts transfer, semiconductor, and other robotic applications. Capable of up to 50 lbs. [222 N] of continuous force and 65 lbs. peak force [289 N] this new series of single axis linear steppers has the motor, bearings and positioning system 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 a linear encoder can be integrated to provide a closed loop system.

Key Features:

• Low profile and small cross section
• High Speed
• Low cost positioning stage solution
• No servo tuning required ·Multiple forcers on a single plate

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 or air bearings. Various 2 & 4 phase "Forcers" can be integrated with "Platens" of varying widths from 1.25 in to 3 in. [31.8 mm to 76.2 mm] for precise sizing of an application. Linear steppers can also be custom designed to meet customer specifications and "platens" are available as bars, single piece tubes, and welded tube assemblies.

H2W Technologies is dedicated to the design and manufacture of linear and rotary motion products that are used in the motion control industry.
