The IMA is a rod-style electric actuator with an integrated
servo motor. Motor windings are rated for 230 or 460V and are potted directly
into the actuator housing. The actuator is capable of up to 2000lbs of peak
thrust for ball screw versions and up to 3300 lbs of peak thrust for roller screw versions. The IMA, with
its high and repeatable force, long life, smooth velocity and compact package
can be used in a variety of industrial motion control applications as a
hydraulic or pneumatic replacement. Applications include press fitting systems,
valve/process control, spot welding, fluid dispensing and many others. The
IMA's integrated servo motor makes for a more compact package than
traditionally mounted motors, by eliminating the need for additional motor
couplers, adapters, belts and/or gears, thereby reducing assembly labor and
parts sourcing. It is available with staggered connectors for convenient
installation and wiring that emulates the most popular motor manufacturers for
compatibility out of the box. The smooth body design eliminates potential
contaminant collection points. A variety of options including mounting and rod
ends, an electronic brake, and IP67 protection make it a flexible linear motion
solution. The IMA uses skewed motor
windings rather than segmented stators to reduce torque ripple and improve
repeatability. The IMA motor incorporates a hollow core
rotor design that further reduces actuator footprint by allowing the screw nut
to pass inside the rotor. The screw is attached directly to the hollow
core rotor, eliminating motor couplers, reducing failure points, and improving
dynamic performance. A patent-pending grease port allows complete actuator
re-lubrication without removing it from fixtures for disassembly, saving
down-time and labor. The IMA has undergone 1.5 years of life testing (Tolomatic
Endurance Technology at work) to validate dynamic load rating capacities.
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.
