The Multiposition Airless Cylinder (MPAC) is electrically driven and complements Norgren's pneumatic cylinders. The device is essentially a linear motor with the moving slider suspended magnetically within the surrounding cylindrical windings. The magnetic field from the permanent magnets in the slider interacts with the field produced by the current in the windings to produce motion. With no mechanical connection between the slider and the stationary stator, friction and contaminating particle generation are minimized—aiding long life.
An MPAC package includes the actuator (with or without a guide), servo controller, and power supply, as well as the all-important software to program and run the system, which eases set up time. The actuator is configured with four variables: light or heavy duty, with or without guides, length of cable connector, and maximum stroke length. The cylinder is programmed via laptop or by "teaching" it directly—moving it by hand and having it remember the position. The controller can store up to eight definable positions within the stroke range, each with its own speed, acceleration, and force parameters. Such guidance information can be stored as a module and retrieved for similar applications in the future.
The MPAC can move loads up to 11 kg at speeds of 2.5 m/sec with accelerations of 40 m/sec2 for the light duty version and 55 m/sec2 for the heavy duty. Repeatability is ±0.1 mm. This performance is targeted at multiple position operations such as high-speed insertion equipment for electronics packaging and semiconductor manufacturing, as well as automatic test equipment, printing, and medical applications. The actuator can also be immersed to IP67 levels, allowing use in wash-down applications. Norgrenhttp://rbi.ims.ca/3849-576
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
