Direct Drive Rotary Tables have 10-20 arc-sec accuracy.

Press Release Summary:




RotoRing(TM) Series rotary tables provide angular positioning and eliminate backlash, friction, and wear problems associated with worm, gear, and belt drives. They combine axial brushless RotoLinear(TM) motoring modules and planar air bearings in compact configuration. Tables provide unlimited rotation and are capable of precise positioning and velocity controls when used with micro-stepping or servo drives. They can be mounted in any orientation.

IntelLiDrives, Inc. released a new RotoRing(TM) Series of direct drive rotary tables that provide superior angular positioning and are designed to eliminate backlash, friction and wear problems associated with worm, gear and belt drives.

They combine axial brushless RotoLinear(TM) motoring modules and planar air bearings integrated in a compact, direct drive configuration. Large area air bearings provide sufficient payload stiffness and maximizes performance in respect to wobble and run-out.

Radially distributed RotoLinear(TM) motoring modules provide high positioning stiffness during rotary indexing and when installed on moving XY tables.

These tables provide unlimited rotation and are capable of precise positioning and velocity controls when used with micro-stepping or servo drives. Can also be equipped with IntelLiCoder feedback for closed loop operation.

RotoRings(TM) tables can be mounted in any orientation and have "large open center design".

When used in processing 12" semiconductor wafers, every area of the wafer can be accessed. In general automation applications large open center offers the opportunity to access parts from inside and outside of the table simultaneously. This feature allows robotic devices, pick and place and ancillary tooling to be mounted inside the table, saving floor space and reducing parts handling with increased productivity.
