The platform delivers high-precision, friction-free motion in demanding, high-performance applications
June 17, 2008 - Danaher Motion, the world's leading provider of motion control solutions, today introduced the Dover MAB-100 linear motor platform. The compact MAB-100 linear motor platform (63.5 mm high x 88.9 mm wide x 266.7 mm long) features a unique air bearing guide that provides extremely precise linear motion with no friction at all, up to 100 strokes Mm. The product also features a non-contact design that improves machine performance, reduces total cost of ownership and maintenance, and reduces downtime compared to contact motor platforms.
Lou Elias, Manager of Small Platform Components at Danaher Dave (Danaher Motion - Dover), said: "The MAB-100 is designed for OEMs to build machines faster and better, offering extremely high trajectories. Accuracy, repeatability and reliability. Therefore, this small platform is ideal for demanding applications in the market segments of life sciences, data storage, semiconductors, factory automation, etc. Since the linear platform uses completely contactless auxiliary components, No particles are produced, and when used in conjunction with an appropriate air intake filtration system, a Class 1 clean room standard can be achieved."
The MAB-100 linear motor platform has no circulating bearings and anti-creep structure, so the resulting motion defects such as friction, temperature rise, and debris are completely eliminated. Otherwise, these motion defects will have a very negative impact on the linear motor platform and overall machine performance. In addition, the MAB-100 is driven by a non-contact brushless servo motor and features a unique dynamic magnetic design. This design eliminates the cables of the mobile motor, which makes wiring easier and improves cable reliability. Overall, the benefits of the MAB-100 include reduced part count, weight reduction, smaller trajectories, and ease of integration into equipment manufacturers and end-user equipment.
Position feedback is provided by a linear optical encoder with a maximum resolution of 5 nm. The encoder includes a pilot signal that enables accurate position recording after power up. The read head is mounted on a fixed base without the use of any moving cables. A built-in, adjustable limit switch ends the stroke sensing and the rubber stopper provides extra protection.
The MAB-100 also features built-in high-performance drivers and controls with an overall length increase of only 58 mm. This model (MAB-100/HRC) requires only a 24 VDC external power supply and an RS-232 series communication link to provide a fully integrated “smart workbenchâ€. The MAB-100/HRC can operate as a master slave on the serial interface or can be programmed to run complex motion sequences automatically as a stand-alone device. The MAB-100/HRC models feature 4096X encoder interpolation for 5 nanometer resolution.
The MAB-100 linear motor platform has a load of 2.5 kg with an accuracy of 1 micron and a bidirectional repeatability of less than 0.03 micron. Maintain slope and yaw within ±7 uradians (±1.5 arc seconds) with flatness and straightness below ±200 nm. Resolution ranges from 5 microns to 5 mm.
