Air-Bearing Platform

Aerotech (Pittsburgh, PA) offers the PlanarHDX planar air-bearing platform for semiconductor manufacturing and advanced test and inspection. Structural elements were designed using a silicon carbide ceramic. The resulting material and structure enable 1.5-m/s scan speeds and 5-g peak acceleration with a payload of up to 20 kg for high-throughput processing. Other features include an air-bearing compensation strategy that increases stiffness and load capacity for high-dynamic applications. The platform uses air-on-air preloading in critical bearing elements, and a proprietary reaction-mass design reduces stage-induced forces in the step-axis that are transferred to the isolation system or structure (optics, sensors, etc.).

Industrial Robot

ABB (Auburn Hills, MI) introduced YuMi, a collaborative dual-arm industrial robot designed for small parts assembly environments. It features dual arms, flexible hands, a universal parts feeding system, camera-based part location, lead-through programming, and motion control. YuMi has a lightweight yet rigid magnesium skeleton covered with a floating plastic casing. The casing is wrapped in soft padding to absorb impacts, enabling the robot to operate in very close collaboration with humans. It has human dimensions and movements, and has no pinch points so nothing sensitive can be harmed as the axes open and close. If YuMi senses an unexpected impact, such as a collision with a coworker, it can pause its motion within milliseconds, and the motion can be restarted again by pressing a button.

Brushless Torque Motors

Allied Motion (Buffalo, NY) released the Megaflux MFH170i series of 170-mm (6.7-in) diameter housed brushless torque motors. The series is comprised of the 170 series brushless torque motor, a digital servo drive, and a programmable optical encoder integrated into a rugged machined aluminum housing with duplex bearings. The motors feature a 63.5-mm (2.5-in) large-bore through shaft. Three stack lengths are available, with peak torque ranging from 8.5 to 16.9 Nm (75 to 150 lb-in), and rated speed to 1000 RPM. The standard winding voltage is 48V. The motors are designed as rotary actuators for use in semiconductor equipment, automated test equipment, scanners, gimbal systems, and applications requiring a rotary actuator with a large hollow shaft.

Stepper Motors

Nanotec (Feldkirchen, Germany) introduced the SC3518 series stepper motors that feature high torque and EMC properties. The 2-phase hybrid stepper motors feature frame size NEMA 14 (35 mm) and a 1.8° step angle; torque is between 0.18 and 0.32 Nm. The motors are connected via an integrated connector that enables easy cable adaption. The two outer pins of the connector are attached to the motor housing. Together with the shielded cable, this creates a shield connection with excellent EMC performance. The motors are available with a shaft end for openloop or sensorless control, or with an integrated optical encoder NOE1 with up to 2,000 increments/rotation.

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
