Rolling Ring

Zero backlash. Jam-proof design.

Uhing®Rolling Ringlinear drives run on a

smooth, threadless shaft that won't clog or

jam. If the system is overloaded, the shaft

simply slips instead of churning and grinding.

The drive bearings are in constant contact with

the shaft, even during reversal, thereby

preventing backlash.

Example applications:metrology machines,

material handling systems, spooling

equipment, packaging & converting equipment.

Many different sizesmeet varying

requirements for axial thrust & linear speed.

Motors | Drives

Food Safe Motor

ABB has launched its IEC Food Safe motors designed for applications

in the food and beverage industry. The motors feature stainless

steel enclosures that have an IP69 water protection rating

and encapsulated winding. The external surfaces are

self-draining and markings are laser etched, avoiding

channels and ridges where contaminants could accumu-

late. The motors can withstand high-pressure sprays and

are fully compatible with clean-in-place (CIP) methods.

The motor line is available in the power

range 0.18-7.5 kilowatt, in 2-6 pole versions

for 230-690 volt at 50 or 60 hertz. They

feature IE3 premium efficiency and flexible

mounting arrangements. The motors come

in frame sizes 71-132.

Stepper and encoder combo

CUI’s Motion Group has launched a line

of stepper motors paired with their AMT11

incremental encoder series. The NEMA-

AMT112S stepper servo motor family is

available in compact NEMA 8, 11, 14, 17,

and 23 frame sizes with a step angle of

1.8-degrees and holding torques ranging

from 3-270oz-in (0.021-1.90N-m). When

paired with a controller, the motor and

encoder combo gives closed-loop feed-

back for a complete servo system. The

high accuracy modular encoder features

22 programmable resolutions from

48-4096PPR, a digitally set zero position

and CMOS voltage output waveforms.

The resolutions are fully programmable

via the company’s AMT Viewpoint soft-

ware without having to remove the

encoder from the motor. Due to propri-

etary capacitive technology, the series is

not susceptible to contaminants such as

dirt, dust, and oil typically encountered

in industrial environments.

Variable Speed Drive

Yaskawa America, Inc. has released the

new GA800 Variable Speed Drive,

designed to control traditional and emerg-

ing motor technol-

ogies through

600 HP. It han-

dles applications

ranging from

simple fans and

pumps to

high-perfor-

mance test dyna-

mometers
