New! Series of High Performance Linear Steppers
Valencia, CA - 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.
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.
