Air-bearing spindles need no cooling

ABS series direct-drive, air-bearing spindles provide angular positioning and velocity control for applications including disk-drive testing, imaging applications, and precision wafer inspection. The ABS2000 is balanced to ISO 1940 G 0.4 tolerances. The design uses labyrinth-type sealing to minimize particle migration from the spindle, resulting in certification for Class 1 cleanroom operation. The low-loss motor produces >0.25 N-m (38 oz-in) of continuous torque with negligible motor losses, eliminating the need for cooling fins and/or external cooling.
