Weldable Couplings and Collars

A line of weldable shaft collars, couplings, and mounts is available from Stafford Manufacturing Corp. (North Reading, MA). The components are made from ANSI 1018 steel and stainless steel to allow users to modify parts and create assemblies without fasteners. Typical modifications include brackets, cams, lever arms, mounts, pins, and rods. They are suited for the design and repair of special machinery, conveyors, packaging systems, and racks. The weldable shaft collars are available in one- and two-pieced, and hinged styles. Flange mounts are offered in ¼" to 6" bore sizes, and weldable shaft couplings are available in ¼" to 2" bore sizes. Smooth-, hex-, and square-bores for shafts, pipe, and tube can be supplied.

Linear Guide Kit

To simplify product selection of self-lubricating linear guides, igus (East Providence, RI) has developed a modular construction kit for belt-driven DryLin ZLW linear axes. The ZLW toolkit enables users to customize their solutions, including rail widths, system length, etc., even for small installation spaces. Cross beams, rails, and/or carriages are available in either aluminum or stainless steel to suit a wider range of application requirements. The ZLW system enables loads up to 165 lbf. to be lifted with stroke lengths of up to 3 meters (118"). Wide drive belts can also permit speeds of more than 5 m/s (16 ft./s), depending on the load. Underwater applications are possible via a special toothed belt.

Motor Controller Provides Custom Electronic Control Solution

A Fortune 200 company needed a turnkey, DC voltage, agency-compliant electronic control solution capable of providing motion control with memory position capabilities and auto run/sense features for a multi-motor application involving four motors. Particularly important to the design criteria was the development of an interactive system of wireless remote control capabilities and other user interface devices, including iPhone and iPad interconnect devices. It was a complicated job, and the company would need to partner with experts who could deliver a time- and cost-effective solution.

Servo Drives

Advanced Motion Controls® (Camarillo, CA) announced AxCent™ servo drives for centralized motion control schemes. The Models AB15A100, AB25A100, and AB20A200 are panel-mount servo drives that operate with brushless permanent magnet motors as well as brushed motors and inductive loads. The drives are controlled with ±10V analog command signals, and use trapezoidal commutation when driving brushless motors. The AB15A100 outputs 15A peak and 7.5A continuous with up to an 80VDC bus; the AB25A100 outputs 25A peak and 12.5A continuous with up to an 80VDC bus; and the AB20A200 outputs 20A peak and 10A continuous with up to a 175VDC bus.

Brush DC Mini Motors

Portescap (West Chester, PA) introduced the 16DCP Athlonix™ high-power-density brush DC mini motors. Available in a 16-mm diameter, the 16DCP motors feature a coreless design with an optimized self-supporting coil and magnetic circuit. The motors are available in two variations — precious metal commutation and graphite commutation — both featuring an Alnico magnet inside. The motors feature a constant force spring design for carbon brush, and an REE (Restriction of Electro Erosion) coil is an available option. With maximum continuous torque up to 2.63 mNm, the motors are suited for medical and industrial pumps, gas analyzers, security and access, and power tools. They are available with encoders and gearheads of various sizes and ratios.
