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.
A new method of modeling how they are created with chemical vapor deposition (CVD) could reduce the cost of carbon nanostructures used for for research and commercial applications, including advanced sensors and batteries.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
