Motion Control

Selecting Miniature Motors for your Medical Devices

The creation of small, portable infusion pumps opened a new chapter in medical care. A patient can receive carefully metered and timed doses of medicine, without requiring a visit to the medical practitioner, allowing life to be less restrictive. Ambulatory pumps have been developed to deliver insulin, nutritive supplements and anticancer drugs.

Integrating Functional Pneumatic Safety Devices into Control Systems

Over the past several years, controls engineers have become adept at applying control systems to machine safety applications. The issue is that safety is a moving target. There are new and revised international standards to contend with. Furthermore, the supplier community is moving swiftly forward in developing solutions that render the old way of doing things obsolete.

Thermoplastic Racks Open Up New Motion Control Applications

Rack and pinions are linear actuators that play a critical role in a wide range of linear motion control applications. While rack and pinions are commonly thought of as a timeless technology, several new developments have helped provide significant performance improvements in specific applications. One new approach, the Roller Pinion System, replaces the traditional rack and pinion with bearing-supported rollers, increasing positional accuracy, speed and durability.

Explosion-Proof Encoder

BEI Sensors (Goleta, CA) announced the Model LP35 explosion-proof and flameproof, low-profile, hollow shaft encoder that features a 2.01" profile and is designed to meet UL, ATEX, and IECEx standards for operation directly in Division 1, Zone 1 environments such as oil and gas. The encoder features a standard removable terminal box, and eliminates the need for an additional intrinsic safety barrier. It is designed for oil and gas applications such as top drives, which have little space to install speed-sensing devices like encoders. The vibration-resistant encoder is built to withstand up to 250G for operation in harsh drilling applications, and operates in temperatures up to 85 °C (185 °F). The encoder’s terminal box configuration allows the unit to be pre-wired. For Free Info Visit http://info.hotims.com/55590-317

Drive System Software

Festo (Hauppauge, NY) introduced PositioningDrives software for designing single-axis drive systems. Engineers input application requirements and the software details the information necessary to create a Festo component parts list, including electromechanical actuator, motor, drive, cables, and other accessories. The software also delivers documentation about the single-axis system to share with internal teams and end users. Once application parameters have been entered, the software identifies single-axis system combinations from a range of components, including electromechanical linear actuators, motors, gear units, drives, and software. Application details entered into the software consist of mounting orientation, load, stroke, and precision. There are also options for specifying the motion profile, including speeds, accelerations, and positioning times. In the design process, combinations of actuator, motor/gear unit, and drive are displayed graphically, and the degree of utilization is shown as a bar graph.

Planetary Gearboxes

Pittman Motors (Harleysville, PA) offers the PLG24, PLG42K, PLG42S, PLG52, and PLG63 planetary gearboxes available with Pittman brush and brushless DC motors. The PLG planetary gearboxes deliver high-torque loads and are suitable for OEM motion control applications such as pan/tilt functions, indexing, pumping, conveying, and traction applications. The gearboxes are suitable for use in designs for medical and laboratory instrumentation, industrial equipment, material handling, and transportation. The gearboxes come in diameters from 24 to 63 mm, and output torques to 100 Nm (74 lb ft). Reduction ratios range from 4:1 to 710:1, with more than ten standard ratios available in each size. Typical versions include gears and ball bearings made of steel or engineered polymer. Custom output-shaft features, lubrication, and reinforced output-shaft assemblies for differentiated solutions can be tailored to specific application requirements.

Rotary Encoder

The Multi Wheel Encoder from Elma Electronic (Fremont, CA) is a miniature rotary encoder that includes an illuminated 8+1 joystick, enabling control using one finger. The encoder features Hall effect sensed incremental encoder output and 12 detents with magnetic indexing to ensure proper alignment and positioning through the life of the encoder. The encoder comes with IP66 sealing, and an outer O-ring for front panel sealing. Measuring 10.5 × 30 mm, the switch incorporates a low-profile design for space-constrained environments. Front or rear mounting is accomplished using two self-tapping screws that are driven into the switch’s polycarbonate body. The front end is metal with clear or black matte plating. The communication interface incorporates a UART output that sends an 8-bit command for every encoder step and joystick actuation, as well as an LED control input with a proprietary protocol. Operating temperature is -20 to +70 °C, and a 3 VDC power supply is required for proper Hall sensor operation. For Free Info Visit http://info.hotims.com/55590-302
