Positioning Medical System Tables Improved Using Rohlix Linear Actuators From Zero-Max
 Patient positioning tables including those used in CT scanning systems can benefit from Roh'lix® Linear Actuators* manufactured by Zero-Max, Inc. With a special "overload" feature, Roh'lix linear actuators halt motion when an obstruction or pre-set level of travel pressure is reached. Thus, positioning systems utilizing Roh'lix actuators are inherently safer than a positioning system that uses a ball screw actuator. ...More >> Lose Weight, Gain Torque with New 35mm Brush DC Motor from Portescap
GE Fanuc Intelligent Platforms Announces Environmental Cables for Servo and Spindle Motors New cables use polyurethane mold to make them stronger to hold up in the harsh environment of the machine tool Charlottesville, VA - GE Fanuc Intelligent Platforms, a unit of GE Enterprise Solutions, today announced the availability of new environmental cables for servo and spindle motors. The power cable connectors have been redesigned to be low profile and the feedback, brake and fan cables now have molded connectors instead of assembled ones. GE Fanuc has a comprehensive line of environmental cables that are specifically designed for use in the rugged environment common to most machine tool applications. The cables cover a wide range of GE Fanuc servo motors and spindle motors used with GE Fanuc's CNC and Power Mate products. Selecting one of GE Fanuc's environmental cables will help ensure the highest quality cable assemblies are present on the final machine tool. The alternative is to spend time and effort designing an in-house cable, which will consume valuable engineering resources, and slow down time to market. ...More >> Plug-in machine controller makes switching to Ethernet-based drives almost irresistible for machine builders  Baldor Electric Company has launched a new plug-in motion/machine control module for its Ethernet-compatible Powerlink drives. The new controller module allows machine builders to eliminate the need for a separate external network controller, along with all of the cabling and panel space that would normally be required. As switching to real-time and deterministic Ethernet-compatible motion control is already proving extremely popular for machinery builders, the additional cost savings offered by this new approach make adoption of the technology almost irresistible. The new Mint Machine Module plugs into a hardware expansion slot in any of Baldor's MotiFlex range of Powerlink-compatible three-phase AC motor drives. Two variations of the card are offered: a dual-axis version that will control the host Powerlink drive plus another external drive via a conventional analog interface, or a high-speed version that will also act as a Powerlink network controller to manage a complete multi-axis control system. Both options are compatible with Baldor's powerful Mint motion language, with its rich development support. ...More >>Survey: Majority of U.S. Teens Feel Prepared for Careers in Science, Technology, Engineering and Mathematics, Yet Many Lack Mentors Lemelson-MIT Invention Index Uncovers Teens' Views of These Fields and the Need for Mentor Support Cambridge, MA - American teens are embracing the subjects of science, technology, engineering and mathematics (STEM) with increasingly positive attitudes; yet many lack the necessary encouragement from mentors and role models in these fields, according to this year's Lemelson-MIT Invention Index*. The annual survey, which gauges Americans' perceptions about invention and innovation, also reveals teens' altruistic intentions and feelings of preparedness to pursue careers in STEM fields. ...More >>New Enhanced Design Delivers 25% More Torque from Portescap’s Industry-Leading h3 Stepper Motors  Portescap, a Danaher Motion company, introduces a stator-enhanced version of its h3 Series Step Motors. New h3 models feature patented enhancing magnets in the stator to provide 25+% more torque output across the entire speed range compared with original h3 models, which already deliver up to 40% more torque than traditional hybrid step motors. "The increased torque is achieved through additional stator magnets that are inserted between each stator tooth. These block the magnetic field from flowing around the stator teeth, which forces more of the magnetic field to flow through each tooth to produce the highest torque output of any hybrid step motor available today," says Dave Beckstoffer, Portescap Product Specialist, Stepper Technologies. ...More >>esd electronics, Inc seeks Papers and Presenters on Fieldbus Applications and Industrial Ethernet Technologies Appeal to engineers, managers, and decision-makers for papers and presentations to be included in esd's annual seminar event. Wilfried Voss, President of esd electronics USA announced his plans to continue the popular CAN (Controller Area Network) Seminar Series in 2009 with the addition of presentations on Ethernet technology and under a new name, "Fieldbus Seminars." Mr. Voss stated, "The technical sessions in 2008 have been very well received and we were very pleased with the attendance." Mr. Voss went on to comment, "besides the basics of CAN, we will put an increased focus on Ethernet based industrial protocols in the 2009 series." In that light, esd contacted the EtherCAT Technology Group who has indicated they are interested in participating at esd's Boston-area conference in October this year. ...More >> New Techno Rotary Table's Small Footprint Provides Long List of Machinery Options  New Hyde Park, NY - Techno, Inc.
