S Series Shaft Motor Has Combined Linear Encoders The S series shaft motors from Micromech has combined linear encoders, encoder guides and mechanical systems. Shaft motors are direct-drive linear servomotors that consist of a shaft with laminated magnets and cylindrically wound coils controlled by the flow of current. They are a simple construction that use magnetic circuits consisting of permanent magnets and coils. Characteristics of the motors include precision positioning, high and low constant speed performance. The standard versions of most motors including linear motors is that the circuits are made of magnetic iron, while shaft motors are not. This means that there is no adsorption force between the shaft and forcer (coil), thereby totally eliminating cogging. Shaft motors are capable of high thrust, for example 2340N with a single forcer and 9360N using four forcers (parallel plus tandem drive). The 'S' series is very quiet due to the absence of friction and the...

SICK Encoders Position Wimbledon Roof Critical to the operation of the roof over Wimbledon's Centre Court is the accurate positioning provided by linear encoders from SICK for each of the 10 77m long, 100-tonne roof trusses. Engineered, manufactured and assembled by specialist hoist and crane designers Street Crane Xpress for the All England Lawn Tennis Club and its main contractor Galliford Try, the roof trusses run on 80m tracks either side of the court roof. Each truss has a SICK KH53 encoder read head mounted at either end, which monitors the truss position and progress across the roof from the KH53's magnetic measurement scale alongside the running track. They are moved by electric motors on either end of each truss, powered from a bus bar system running the length of the track. In addition, to the linear encoders, SICK supplied SRM50 Hiperface absolute rotary encoders to monitor the rotational positioning of each motor. The motors move the 10 trusses across the roof b...

Industrial Encoders for Dummies US manufacturer BEI has teamed up with the iconic "For dummies" brand to produce an innovative tutorial guide on industrial encoders. Aimed at novices and experts alike, "BEI industrial encoders for dummies" reaches beyond the primer to provide an interesting, informative and very readable 42-page reference covering optical encoder technologies and applications. This free guide, available from BEI's exclusive UK and Ireland distributor, Variohm EuroSensor, provides a detailed overview of incremental and absolute optical encoders and how they are applied in real world applications; with hints and tips on key specifications, system design information, installation procedures and environmental considerations. There is also a "things to know about your manufacturer" chapter that aims to deal with true cost of ownership issues and supplier evaluation. The book also takes time to entertain with some fascinating and surprising ...

Magnetic Encoders Boost Dragster Speed Visitors to Renishaw's stand at Mach 2008 (hall 5, stand 5140) will be able to see Team Salakazi's KTM Super Twin nitromethane fuelled dragster which takes just 6.7 seconds to cover a 402m race track, achieving speeds of around 322km/h. Aided by Renishaw's rotary magnetic encoders that monitor crankshaft position and clutch speed, this 360kg 'rocket' generates 1417kW from just a 1995 cc engine. Not many people would even consider sitting astride a snarling 1417kW engine travelling at over 300km per hour. But Jaska Salakazi from Finland has made a career of it, becoming the first person in the world to break the seven-second barrier over 402m on a Super Twin Top Fuel bike. Since 2000, the speed-obsessed six-man team at Salakazi Racing has continually designed, built and refined its KTM Super twin powered Dragster. A recent modification is the addition of two RM22 compact high-speed rotary magnetic encoders, produced by Renishaw...
