Air Bearing Linear Motor Positioning Stage - ABS-012-12-030-X

H2W introduces its latest high precision air bearing linear positioning stage (ABS-012-12-030-X). The ABS series stage incorporates five magnetically preloaded air bearings for both load carrying and lateral guidance. The base of stage is constructed using a lapped granite surface plate and the lateral guidance is controlled by a granite straight edge that is mounted to the base.
The non-contact 3 phase brushless linear motor operates in conjunction with a high resolution linear encoder for closed loop operation. The ironless core coil assembly has no magnetic attractive force to the stationary magnet assembly, and as a result it does not induce any cogging into the system. The lower moving mass of the stage allows for much higher accelerations of light payloads.
The stage has a stroke of 12 in [300 mm]; generates 20 lbs [89 N] of continuous force and 60 lbs [267 N] of peak force. It includes a 1 micron resolution linear encoder.
H2W's line of air bearing positioning stages are ideal for high precision applications requiring extremely flat and straight, non-contact motion.
Features:
- Non-contact air bearing operation
- Excellent flatness and straightness specifications
- Lowest velocity ripple
- No wearing parts
- Custom strokes and force configurations available

Great piece of work! It's being kept in alignment bij magnets actually preloading the air pads on the vertical plane?

[@ROTEsimplemachines]

Great capacity- is it possible to increase load if velocity is greatly decreased? Is velocity variable at low speeds and is traction possible? You know, for dramatic effect.

[@ben-3d]

Relly cool, how high is the gravitation factor from 1kg filament on this bed on the maximum acceleration/speed ?

[@Moronicsmurf]

this would be interesting to put in a laser cutter or plasma cutting machine with a higher degree of precision.

[@AndreBAnderson]

how do you actuate it? is it with air? I don't see a ballscrew or other actuator?

[@nicholaswilliams4507]

It's using a linear motor. Notice the magnets on the center bar area - they act the same as the magnets in a motor, just "unwound" into a straight line. The moving stage will contain the stator coils that are energized and interact with the magnets to produce motion. Google "linear motor design" for more info.

The big question is how much

[@sto2779]

those wires at the back will add frictions
