Leveling Mounts

The V10Z44MCM Series of 3-in-1 leveling mounts from Advanced Antivibration Com - ponents (New Hyde Park, NY) dampens shock and vibration, provides leveling, and offers position mobility for packaging machinery applications. They incorporate a moveable mount in which the rubber mount is incorporated with a rotating ball. The maximum recommended load of the two isolators ranges from 200 kgf to 600 kgf (441 lbf to 1323 lbf). The diameter of the unit base ranges from 100 mm to 140 mm (3.9" to 5.5").

Vacuum Cups

Vi-Cas Manufacturing (Cincinnati, OH) offers vacuum cups in sizes to 15" in diameter to lift and manipulate large, bulky, or cumbersome materials like aircraft fuselage segments and fabricated assemblies. Round, rectangular, or oval cups are available for a variety of lift manufacturers. Sizes and types are available to fit virtually any type of vacuum equipment used for lifting, manipulating, or “pick-and-place” applications. Materials are available to suit applications such as food handling, high-temperature materials, anti-static for handling electronic components, and non-marking materials for sensitive products.

Permanent Magnet Motors

NovaTorque (Fremont, CA) offers the Gen2.0 PremiumPlus+™ Electronically Commutated Permanent Magnet (ECPM) motors in 3hp and 5hp 2400-rpm (maximum speed 3600 rpm) models. Also available in 3hp and 5hp 1800-rpm models (maximum speed 2700 rpm), the motors utilize ferrite magnets. Driven by variable frequency drives, the motors feature motor-only rated point efficiencies of 93.0 and 92% percent for 3hp and 5hp versions, respectively. The motors are packaged in standard NEMA frame sizes and mounting dimensions. They are available both in the mounting frame size typical for induction motors, as well as one frame size smaller, and are compatible with variable frequency drives (VFDs) from most leading manufacturers.

Servo Drives

Elmo Motion Control (Nashua, NH) offers the Gold Bell and Gold DC Bell servo drives for stepper motors. The Gold Bell servo drive weighs 55 g (1.94 ounces) and operates at 20A/100V, delivering 1.6kW continuous power (3.2kW peak power) with multiple voltage ratings of 12V-95V. The PCB-mounted driver is designed to operate in a closed loop (single or dual feedbacks), or in open loop, and has a “smart” control-supply algorithm enabling it to operate with only one power supply.

Motion Tracking System

InvenSense (Sunnyvale, CA) has introduced the MPU-9250 9-axis motion sensing device housed in 3 × 3 × 1 mm QFN package. The full integrated device includes a gyroscope, accelerometer, and electronic compass, with an onboard Digital Motion Processor. The accelerometer consumes 6.4 mA of current in low-power mode. The compass has a resolution of 16 bits, and full-scale measurement range of ±4800 μT. It is supported by the company’s MotionApps software. The software drivers are fully compliant with Google’s Android 4.2.1 Jelly Bean, Microsoft Windows 8, and Windows RT releases, and support low-power DMP capabilities that offload the host processor to reduce power consumption and simplify application development.

Miniature Slide Guides

NB SEBS-B type slide guides from NB Corporation (Hanover Park, IL) feature standard clearance. The SGLS all-stainless models are suitable for high-temperature applications, cleanroom, and vacuum environments. They are available in both retained-ball (whose elements allow for easier handling since the guide block may be removed from rail without ball loss) or low-cost nonretained- ball lines. Sizes range from 2 mm, and friction-free travels range from 104-mm to 1000-mm rail lengths.
