Clutches

U.S. Tsubaki Power Transmission, LLC (Wheeling, IL) announced Cam Clutch unidirectional/ mechanical clutches that lock the inner and outer races through the locking action of cams, transmitting torque in one direction of rotation while overrunning in the other. The cams are made of alloy steel, and the races are made of alloy steel with high surface hardness and core toughness. They are precision-ground to provide concentricity and surface finish for accurate cam rotation. For Free Info Visit http://info.hotims.com/55588-308

Linear Motors

Heidenhain (Schaumburg, IL) offers ETEL ILF and ILM series ironless high-speed linear motors for use in the semiconductor and electronics industry. The motors utilize an ironfree coil design for zero-attraction force between the carriage and the magnetic way. The ILF is a smallersized motor for very high dynamic and low-moving mass applications; the ILM is a more powerful version of the ILF, and has an option to be air-cooled to increase continuous force output. The ironless motors come in a variety of lengths and heights with different degrees of force, and share the same profile so that one is interchangeable with the other. The motors can reach speeds of up to 20 m/s and peak force of up to 2,500 N. They are designed for direct drive applications and offer no backlash, fewer parts, and require no maintenance.

Electric Cylinder

SMAC (Carlsbad, CA) introduced the CBL50 electric cylinder designed to achieve peak force of 50N at 2 Amp current, and acceleration up to 40G. It features carriage-free design and built-in linear bearings. It is available with a vacuum and spring option for pick-and-place applications. With the optional IP65 and IP67 dustproof and waterproof feature, the cylinder is suited for applications such as food and beverage processing, packaging, and pharmaceutical industries. Stroke lengths of 10, 25, 50, and 100 mm will be available. The cylinder is offered with a choice of encoder resolutions, with 5-micron standard, and 1 and 0.1 micron optional. It is fully programmable in position, velocity, and force simultaneously. A patented “Soft-land” function ensures precise contact force. For Free Info Visit http://info.hotims.com/55588-305

Pump Drive

The Drives & Motion Division of Yaskawa America (Waukegan, IL) released the iQpump Micro intelligent pump drive for variable-torque pump loads through 25 HP. It is available in NEMA 1 and NEMA 4X rated models. A variety of package options are available, and integrated pump-specific software enables a range of pumping applications from constant pressure, flow, geothermal, and multiple pump booster systems, to wet well lift stations and others. The pump automatically adjusts operating conditions to meet system demand. For Free Info Visit http://info.hotims.com/55588-309

Stages

Optimal Engineering Systems (Van Nuys, CA) released low-profile XYθ (theta) stages that move in an XY-plane and rotate around the center of the XY-plane. Available in 12 models in two precision grades, the stages have linear travels from ±2 by ±2 mm, up to ±30 by ±30 mm. The stages can rotate around the center of the XY plane up to ±6°. Four models have solid tables sized from 100 x 100 mm to 200 x 200 mm, and eight stages from 250 x 250 mm to 1500 x 1500 mm are hollow core (open frame) stages. Available in normal and precision grades, they have preloaded cross roller bearings, and typical normal repeated positioning accuracy is from ±1.75 μm to ±2.5 μm; typical precision repeated positioning accuracy is from ±0.7 μm to ±1.0 μm. Parallelism of the stages is as low as 30 μm, and the larger stages can handle dynamic loads to 600 kg. The stages can be ordered with linear encoders for closed loop operation, customized to meet specific requirements, and complete ready-to-run alignment systems.

Nanopositioning Stages

Aerotech (Pittsburgh, PA) offers the QNP-XY series piezo nanopositioning stages with resolution to 0.15 nm, linearity to 0.007%, and repeatability to 2 nm. The stages provide a variety of travel lengths (100 μm to 600 μm), feedback options, and vacuum versions, as well as resonant frequency up to 885 Hz. The capacitive sensors measure the output of the positioning carriage directly. The stages are available with capacitance sensor feedback or without feedback (open-loop). Open-loop provides an option for applications where compact size, high dynamics, and subnanometer positioning resolution are required, but absolute positioning accuracy and repeatability are not required. Open-loop designs can also be used where the piezo position is controlled via an external feedback source (interferometer, vision system, photodetector, etc.).
