Raw Power to the Rear Wheel
 The 360 kg KTM dragster does a quarter mile in 6.7 sec at a terminal velocity of 316 kmh (196 mph). A preprogrammed clutch, enabled by Renishaw encoders, allows the motorcycle to read clutch speed before the rear tire completes its first rotation. In this application story, encoders monitor crankshaft position and clutch speed to determine road conditions.

Posing as a Digital Potentiometer
 Need a digital potentiometer for a car audio, air-conditioning, or navigation system application?
These rotary mechanical encoders take motion and convert it into a sequence of digital pulses. The two-bit, gray code incremental encoders boast a rotational life of 30,000 cycles with an operating temperature range of -30° C to +85° C.

Slide into Action
 Typically, one designs a machine based on available components. Not so with the MS46 aluminum positioning slide, available in any desired length. As the carried axis in a multi-axis assembly, the light-weight slide minimizes the total moving system mass so that smaller motors can be used. Applicable in factory automation, life science, packaging, and semiconductor industries.

Micro-Commanding Rotational Position
Feedback from the shaft-angle resolver micro-commands the servomotor in this micro-commanding rotational position control system. The system also boasts lighter weight, less cost, and fewer mechanical problems than its cousins based on stepping motors and gear drives.
Developers say that the key to the system is its position-feedback signal-conditioning circuits. |

The Precision Alliance
Linear Bearing is Immune to Contamination
The MONORACE linear bearing family is ideal for dirty and harsh environments. Where most bearing ways utilize a ground groove, the MONORACE bearing surfaces are raised and do not collect and hold debris. Further, the rails are chemically treated to yield excellent corrosion resistance. View our product catalog.

One More Bottle of…
 A Russian bottle packaging company needed a 50,000 bottle-per-hour throughput, a long machine availability, and the flexibility to wrap many different sized bottles. In this case study, engineers explain how they developed a continuous production process with a six-axis motion control system based on the Trajexia motion platform.

PACs Address Market Needs
 "Programmable Automation Controllers address the integration issues confronting OEMs by extending the domain expertise of automation systems," says Craig Resnick of the ARC Advisory Group. This means increased return on assets and reduced life-cycle costs. The ADAM-5550KW, a PAC, handles jobs requiring the features of both PLCs and Industrial PCs.

Actuator Positions Itself with Force
A new-old idea — air over electronics — gives this patented hybrid actuator the speed and accuracy of electric actuators with the force of pneumatics. Engineers used this hybrid to replace pneumatic cylinders in an ultrasonic welding application for drink cartons. This solution eliminated external electrical sensors, reduced wiring, noise, and downtime required for cylinder replacement. |
Why Use a Rotary Actuator?
 In this short tutorial of rotary actuators, the writer explains their many advantages. For example, rotary actuators can replace several components while functioning as a rotating device, mounting bracket, and bearing support. The cut-away diagram shows how they operate.
