Dc micromotor works longer

A new motor design, Smartshell, exceeds the operating lifetime of electromechanical commutated dc micromotors. The all-in-one design concept — lamination stack, coil, and PCB combined in a single molded component — provides motors with a durable housing. The rotor consists of a permanent (NdFeB) magnet fitted onto a through-shaft supported by preloaded ball bearings. The motors are available in different frame sizes and can be fitted with different optional modules, such as analog or digital hall sensors. The phase-commutation sequence of the motor is made electronically by an external servo amp. Precision gearheads adapt the rotation speed for the application.

Electric actuators push over 2,500 lb.

The MXE Series of rodless screw-drive electric actuators include three new body sizes. All 12 MXE models combine multiple screw technologies and increased load capacities to deliver a flexible and reliable electric actuator. Load capacities range from 35 to 2,583 lb for Fz loads, and increased moment loads. MXE also has high-load stability and offers a low carrier height to reduce overall actuator envelope. Magnetically retained stainless-steel bands are durable, corrosion resistant, and flexible to deliver long-lasting operation, without the elongation common to elastomer and nonmetallic bands. The bands protect internal components from contamination to increase uptime. MXE comes in inch and metric sizes and features internal magnets to support sensors and switches.

Flexible corrugated tubing turns corners without reducing flow

Tex-Flex FEP corrugated tubing turns sharp corners with small bend diameters without reducing the inside diameter of the tube. The bend diameter is almost four times smaller than a typical smoothbore tube of the same size. Increased bend diameters let the tubing work well in confined spaces, wrapping around machine legs and other obstacles that would normally restrict or kink a smoothbore tube. The tubing is lightweight, seamless, and clear, allowing operators to monitor any material passing through the tube.

Orthopedic module added to medical-materials database

The Materials for Medical Devices Database supports medical-device design. The relational and modular database features material properties and biological-response data for medical-device designers. The orthopedic module focuses on material used in spinal implants, and applications such as spinal interlaminal fixation orthosis, spinal intervertebral body fixation orthosis, and pedical screws spinal systems.

Laser works with copper mirrors

The LT-4 laser cutting and welding tool uses water-cooled, parabolic copper mirrors instead of lenses to focus the laser beam. Thermal effects are much less than with lenses and the copper mirror cannot crack.
