Linear motor driven XY positioning stage
3 - 120" H2W Technologies, Inc

The DR stage 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.

The iron core coil assembly is magnetically attracted to the stationary magnet assembly, which provides a 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

The larger size of the stage 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 DR positioning stage incorporates the latest in linear motion technology.

- Motors: 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.
- Bearings: Linear guidance is achieved by using a 2 parallel linear rail with 4 linear recirculating ball bearing guides. The bearing guides are sealed with wipers to contain the lubrication and to keep out debris. Periodic lubrication of the guides is recommended.
