PI Intros High Performance Direct-Drive Rotary Stages
AUBURN, MA — PI is introduc- ing a new series of direct-drive, ball bearing rotary stages to sup- plement their A-62x series of air bearing spindles.
Based on PI’s extensive
knowledge in the design and manufacture of ultra-high-preci- sion rotary tables with air bear- ings, the new V-62x mechanical
are at the heart of the direct-drive rotary stages, transmitting torque directly and friction-free to the motion platform. Advantages of a direct-drive design over a worm gear drive are higher veloc- ity and acceleration, faster response, as well as the total lack of backlash and no friction in the drive train. Absolute encoders supply
explicit position information that enables the direct determination of each angular position — a great advantage over the tradi- tional counting of increments. Therefore, position information
is immediately available after power up without referencing, improving both efficiency and safety during operation. Single and multi-axis, ACS-
based motion controllers and servo drives are available for sin- gle axis applications of the rotary stages or multi-axis, multi- degree-of-freedom sub-assem-
blies — also available from PI. Contact: PI (Physik

High Force Linear Servo Motor from Moticont
V-62x rotary stages. The V-62x stage family is
designed for 24/7 applications that require high precision motion with eccentricity and flat- ness deviations below 1 µm and high stiffness. The new rotary stage family
can be mounted and operated in any orientation, a critical feature for many industrial automation applications.
bearing rotary stages were designed to provide exceptional performance regarding travel accuracy, flatness, and wobble. The ultra-precise deep groove ball bearings are preloaded and lubricated prior to delivery, meaning they are maintenance- free for the whole lifetime of the rotation stage. Three-phase torque motors
VAN NUYS, CA — A high force linear DC servo motor from Moticont has been added to their expanding line of voice coil or moving coil motors. The LVCM- 095-038-01 linear voice coil motor is a true servo motor fea- turing zero cogging, high accura- cy, and high repeatability when operated in a closed positioning loop.
Clean non-commutated,
zero cogging, zero backlash voice coil motors (also referred to as

motors. This LVCM-095-038-01 linear servo is 3.75 in. (95.3 mm) in diameter and has a continu- ous force of 23.1 lb. (102.7 N) and a peak force of 73.1 lb. (324.4 N) at a 10% duty cycle. This brushless, energy effi-
cient, smooth motion, compact servo motor just 2.250 in. (57.1 mm) long at mid-stroke, and fea- turing low inertia, high accelera- tion/deceleration, and high speed is ideal for: Work holding and clamping, assembly, positioning, sorting, testing, wafer handling, dynamic vibration absorption, medical devices, industrial and packaging applications. The motor features a pat-
tern of four 10-32 UNC-2B threaded mounting holes in the housing and in the coil end to easily integrate into new or
existing applications. Contact: Moticont, 6901
