Shaft Locking Bushings

Zero-Max (Plymouth, MN) offers ETP Techno shaft locking bushings for bore sizes of 110, 120, and 130 mm. They are designed for locking components to large shafts with repeatable precision for applications requiring frequent mounting operations such as position gears, pulleys, sprockets, and other components in automated machinery. Handling torque ranges from 247,820 inch lbs. to 283,223 inch lbs., the bushings feature a radial screw design for mounting, repositioning, and phasing of components to the shafts. They can be readjusted hundreds of times without any axial movement of the bushing or component along the keyless shaft. An Allen wrench is required to mount and lock the bushings into place.

Fasteners

Fixtureworks® (Fraser, MI) offers Imao® “One-Touch” pin-and-receptacle fasteners used to attach fixtures, plates, machine covers, and more, joining components with moderate clamping force. An alternative to nut-and-bolt assembly, the fasteners provide secure changeover and installation without the need for tools. The fasteners are available in quarter-turn, knob-locking, button-locking, ball-lock clamping, and magnet-lock clamping pin styles.

Motor Drive Software

Teledyne LeCroy (Chestnut Ridge, NY) announced three-phase Motor Drive Power Analyzer software for its HDO8000 oscilloscopes for motor drive embedded control and power section debug. With the addition of three-phase power analyzer capability, and motor speed and torque integration, the drive system can be validated and debugged, and drive and motor power and efficiency measurements may be performed. The software is used by motor, motor drive, variable frequency drive, variable speed drive, industrial automation, and motion control equipment manufacturers. Design engineers that integrate motors into their designs also can utilize the software to validate proprietary controls and complete drive system designs.

Motor Gate Drivers

Microchip Technology (Chandler, AZ) offers the MCP8025 and MCP8026 3-phase brushless DC (BLDC) motor gate drivers with integrated power module, LIN transceiver, and sleep mode. The devices can power the dsPIC® digital signal controllers (DSCs) and PIC® microcontrollers (MCUs), driving MOSFETs, sensing current, preventing short circuits, outputting zero crosses, controlling dead time and blanking time, and monitoring for fault conditions such as over/under-voltage, over-temperature, and other thermal warnings.

HEV Motors

Parker’s Electromechanical Automation Division (Rohnert Park, CA) announced the GVM142 HEV motors. The generator and auxiliary motor series is an electric machine intended for use in electric and hybrid electric vehicle (HEV) accessory applications such as high-power alternator replacements and electrohydraulic pump control. They feature a 142-mm frame size with an SAE A adapter mount to be close-coupled to hydraulic pumps. Within this frame size, there are three rotor lengths and dozens of winding variations that enable more than 100 combinations of base speed and power output for ultimate scalability and fine-tuning to the vehicle’s exact power generation or electrohydraulic requirements. The motors have rated power from 2.6kW to 30kW+, rated torque up to 36Nm, rated speed range from 1600 to 9800 RPM, peak power densities up to 3.7 kw/kg, operating voltages from 24VDC to 800VDC, and SAE J1455 environmental standards.

Positioning System

Physik Instrumente (Auburn, MA) offers the H-850KMLD 6-axis hexapod positioning system with 1,000-pound load capacity that provides 1-μm minimum incremental motion over a 100-mm travel range in XY, and 0.5-μm in the Z direction. Repeatability in the three linear axes is ±1μm, and ±5μrad/9μrad in the rotary axes. The hexapods include a controller and software package. The dedicated C-887 hexapod multiaxis-vector controller is commanded directly in Cartesian coordinates. The user can specify a random pivot point in space with a single software command. LabVIEW and text-based programming languages under Microsoft Windows or Linux are supported by libraries and program examples. For loads above 2,000 pounds, standard H-845 and custom hexapods are available.

Enabling Microliquid Chromatography by Microbead Packing of Microchannels

The microbead packing is the critical element required in the success of onchip microfabrication of critical microfluidic components for in-situ analysis and detection of chiral amino acids. In order for microliquid chromatography to occur, there must be a stationary phase medium within the microchannel that interacts with the analytes present within flowing fluid. The stationary phase media are the microbeads packed by the process discussed in this work. The purpose of the microliquid chromatography is to provide a lightweight, low-volume, and lowpower element to separate amino acids and their chiral partners efficiently to understand better the origin of life.
