H2W now offers a revolutionary series of single-axis linear stepper stages that integrates a linear encoder into the stage to operate the linear stepper motor as a 2-phase brushless motor when coupled with an advanced motion control electronics package provided by H2W. When operated this way, the motors will tend to run cooler, as they will only draw the current needed to hold the desired position or to make the desired move.
The new series, LSS-031-04-011-MEA, is powered by H2W’s linear stepper motor STS-1220-AP3, which generates a force of 11.0 lbs (48.8 N) with a total stroke length of 31.0 in (788 mm). Integrated air bearings maintain the required motor air gap. The customer must supply 60-80 psi of filtered compressed air for proper operation of the stage.
The integrated 1.0-micron resolution encoder works with the control package to operate the stepper motor as a two-phase brushless linear motor, which generates higher speeds and allows for precise positioning.
Operating at high speeds could lead to cable fatigue and failure. To address this, the forcer and stage have a high-flex power cable and cable carrier for protection against fatigue and failure. Some provisions also allow the routing of customer cables within the cable carrier.
Custom mounting holes on the moving table are available upon request at no additional charge.
