The XRS series positioning stage are compact, small cross section open or enclosed stages for short stroke linear servo applications (up to 12 in stroke). It is driven by either an iron core or ironless core 3-phase brushless linear motor and guided by 2 sets of parallel cross roller bearings. The stage can be with enclosed end covers and a set of bellows.
The dual parallel rail sets offer excellent load carrying capability.
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 small overall package size makes the XRS stage ideal as a Y or Z axis for short stroke positioning applications.
The XRS stage comes standard without bellows (folded way covers) , but they can be added as an option.
A cable carrier is not supplied with this stage because of the short stroke, but can be added as an option, if desired.
1) non-contact 3 phase brushless , low cogging, iron core linear motor, commutated either sinusoidally or trapezoidally with Hall Effects. There is a large magnetic attractive force which provides a preload for the crossed roller bearing system. The encapsulated laminated coil assembly moves and the multi-pole single sided permanent magnet assembly is stationary.
Bearings: Linear guidance is achieved by using a 2 parallel sets of crossed roller rails. The rollers and retainer are not sealed Periodic lubrication of the guides is recommended.
Cable Carriers: Non standard can be added as an option.
Bellows: Non standard can be added as an option.
The cross roller bearings in the stage should be periodically lubricated with the manufacturers recommended grease. The open glass encoder scale should be wiped with a glass cleaner occasionally to ensure trouble free operation.
