Laser
Edge Direct-Drive Rotary Stages
Aerotech
offers a variety of direct-drive rotary stages designed to meet a wide range
of applications. All Laser Edge rotary
stages
utilize brushless, slotless, direct-drive motors. The direct-drive feature of
these stages provides superior speed and
acceleration
capabilities when compared to worm- and screw-based designs. Brushless operation
allows continuous 24/7
maintenance-free
operation while the slotless motor construction exhibits zero cogging for ultra-smooth
velocity regulation.
These
high-performance rotary stages feature outstanding velocity, wobble and runout
specifications unattainable in worm
drive
and screw-based stages. Various mounting, encoder, slip ring, and rotary union
options are available.
