Motor Drive

The RoadRunner SoftStep R213S microstepping motor drive from Testra Corp. (Tempe, AZ) features an onboard processor that treats the input steps as small vector moves, and chains them together with 250 or 256 microsteps per regular motor step with controlled accelerations. Dual chopper stabilized current comparators and auto-calibration eliminate communication discontinuities and maintain sine wave drive, reducing motor noise. The drives are equipped with jumpers installed with a divisor setting of 10 to make them Geckodrive compatible; jumpers can be reconfigured by the user. The drive microsteps in either 250 or 256 increments per step for DS (double-step) settings, 1 (full-step), 2 (half-step), 4, 8, 16, 32, 64, 128, and 256. The drive measures 2.5 × 2.5 × 0.825", input power is 20VDC – 80VDC, and current drive is 1 to 7 amps. Other features include resistor programmable current, opto-isolated inputs, and step frequency to 5 Mhz. Available options include custom waveforms to match individual motor characteristics, and user-programmable waveform. For Free Info Visit http://info.hotims.com/61062-301

Linear Slide

Haydon Kerk Motion Solutions (Waterbury, CT) introduced the WGS Wide Guide Screw linear slide that utilizes a screw-driven carriage. Length and speed are not limited by critical screw speed, allowing high RPM, linear speed, and long stroke lengths. The slide offers stroke options of 6, 12, and 18" in three leads (0.1, 0.5, and 1.0"). Each slide comes with a size 17 and a size 23 motor mount. The slide utilizes sliding plane bearings on a low-profile aluminum guide rail. The lead-screw is made of stainless steel, and all moving surfaces include Kerkite® polymers running on a Kerkote® TFE coating. The slides come with wear-compensating, anti-backlash-driven carriages. Additional driven or passive carriages can be added, along with application-specific customization. Linear guides without the drive screw also are available.

Angle Sensors

Novotechnik U.S. (Southborough, MA) introduced the RSX-7900 Series angle sensors that provide up to IP69K ingress protection and ISO13849 PL-d safety compliance in a non-contacting design. The sensors are available in six standard measuring ranges with angles from 0 to 60, to 0 to 360 degrees with unrestricted rotation. Resolution is 12-bits across a 4 to 20 mA output, with linearity to ±1% at ≥ 90 degrees. Repeatability is 0.2°, and update rate is 5 kHz. Single and dual redundant versions are available. The sensors offer anodized aluminum housing with a stainless steel shaft for corrosion protection with salt and spray resistance. Axial and radial shaft loading is up to 300 N via a double-row angular ball bearing design. The 70-mm-diameter sensor has a nominal length of 35 mm, and is available with a choice of shaft styles.

Hexapod

Aerotech (Pittsburgh, PA) offers the HEX500-350HL high-load, six-degree-of-freedom hexapod for applications in sensor testing and high-force device manipulation. It is actuated with six struts that are built with preloaded bearings, ball screws, and drive components, and is driven by AC brushless, slotless servomotors that are directly coupled to the actuator ball-screw for drive stiffness and minimum incremental motion of 20 nm in XYZ and 0.2 μrad for θxθyθz. The platform and base can be modified with user-specific features or mounting patterns.

Level Indicator

The Model BM-T tilt Switch from BinMaster (Lincoln, NE) is a level indicator used for point level detection of heavy materials in bins, tanks, or silos, or over a conveyor belt or open pile. It is suspended vertically over a control point using a wire rope, chain, or flexible hanger. As the material level rises, the switch tips and causes a steel ball within the unit to shift position. When tilted to 15°, it activates a microswitch and causes an alarm condition. A stainless steel paddle is attached to the stainless steel shaft when the switch is used in rock, aggregates, or other heavy solid materials. A plastic sphere is suitable for lighter powders and solids. For Free Info Visit http://info.hotims.com/61062-305

Machine Controller

Mitsubishi Electric Automation (Vernon Hills, IL) introduced the iQ-R Series machine control system that incorporates sequence, motion, safety, process, and C language control into one platform. The control platform is designed for applications requiring integrated motion and safety control, tight synchronization between various processes, and high production throughput. The integrated design allows machines or production lines to consolidate control in one rack. The system can have up to 4 CPUs per rack for various combinations of motion, sequence, or process control.
