3.2. Product Features
The A-62x series stages all incorporate completely non-contact fully preloaded air bearings, direct-drive torque
motors, and optical position feedback encoders to provide a maintenance free stage. There is no mechanical
contact to wear or require lubrication, making these stages ideal for clean room and medical applications. The
brushless torque motor uses an ironless slotless motor coil, which means there is zero cogging and no attractive
forces
– resulting in unsurpassed smoothness of motion. This is especially useful in applications where velocity
control is important.
The air bearing, motor, and encoder are housed in the internals of the stage and are not visible to the user.
