High Speed, High Force Stage Provides Very Stable Platform

Santa Clarita, CA -- The DR stage incorporating the latest in linear motion technology, from H2W Technologies, Inc., is a low profile, wider footprint, enclosed positioning stage. It is used in closed loop positioning applications that require high speed and high accelerations of heavier loads. Features include: Travel up to 160 inches [4m] at Velocities of 200 inches/sec [5 m/s], Acceleration to 9 G's, Continuous Force to 445 lbs [1978 N] and Peak Force to 1335 lbs [5933 N], and Resolutions of .00004" or .0002 [1 or 5 micron].

Additional specifications include: Flatness ±.0008" /ft [±66 micron / meter], Straightness ±.0009" /ft [±74 micron / meter], Accuracy* ±.0007" /ft [±57 micron / meter], Repeatability ±.0003" [±7.5 micron], and Load Capacity 442 lbs [100 Kg].

The iron core coil assembly is magnetically attracted to the stationary magnet assembly, which provides preload for the bearing system. The dual parallel linear bearing rails with 4 linear recirculating ball bushing guides provide a much higher load carrying capacity. The wide low profile of the stage ensures a stable platform for the payload or as the bottom axis (X axis) of a stacked multi-axis system.

It is the larger size of the stage that allows for the mounting of a larger, higher force linear motor. The DR stage comes standard with bellows (folded way covers) with a 12:1 extension to compression ratio.

The cable carrier is oversized to allow for passage of customer payload cables and hoses. The back of the cable carrier can be easily removed and reattached to route through additional cables.

The Linear Motors used in the DR stages are non-contact 3 phase brushless , low cogging, iron core linear motor, commutated either sinusoidally or trapezoidally with Hall Effects. The encapsulated laminated coil assembly moves and the multi-pole single sided permanent magnet assembly is stationary. There is a large magnetic attractive force which provides a preload for the bearing system.

Linear guidance is achieved by using 2 parallel linear rails with 4 linear recirculating ball bearing guides. The bearing guides are sealed with wipers to contain lubrication and to keep out debris.

Non-contact glass or metal scale optical linear encoders with a reference mark for Homing are integrated into the DR Stage. Multiple reference marks are available and are spaced every 50 mm down the length of the scale. Typical encoder output is A and B square wave signals but sinusoidal output is available as an option

End of travel limit switches are included at both ends of the stroke. The switches can be either active high (5V to 24V) or active low. The switches can be used to shut down the amplifier or to signal the controller that an error has occurred. The limit switches are typically an integral part of the encoder, but can be mounted separately if required. Hard stops are incorporated into the ends of the stage to prevent over travel damage in the event of servo system failure.

* Water Cooling option on linear motor coil assembly doubles continuous force rating (peak force rating stays the same)
