PDU2M is comprised of a rigid but lightweight aluminum slotted profile fitted with a toothed belt drive and carriage which effectively encloses the unit. Rated for operating speeds up to 6m/s and loads up to 750N, PDU2M’s 20AT3 belt allows for driving forces up to 280N. Left, right or double drive shafts can be specified together with a range of options such as brakes, positioning encoders and mechanical or inductive limit switches. Internal bumpers provide end of stroke protection at both ends.

Key to this unit is the extra ultra-high performance HepcoMotion Herculane® wheels that are mounted on adjustable eccentric studs. These wheels run virtually friction-free on the inside of the profile providing stable support for the carriage plate; felt wipers sweep debris from their path. Several carriage styles are available to allow for quick and easy construction of multi-axis systems with minimal brackets and hardware.

PDU2 is fully compatible with aluminum profile systems (which Bishop-Wisecarver carries) and is an ideal replacement for failing ball-based systems that are unable to match its speed and reliability.

The lightweight design feature low 32 mm profile height and incorporates anodized aluminum body with pre-loaded ball bearings with run-outs of 5 microns. This proprietary bearing design provides smooth rotation with minimal wobble.

A precision ground worm gear produces consistent driving torque to the rotor and eliminates variations in the motor current.

RTHM-100 stages feature an angular resolution 0.1 arc-sec, which may be achieved with either DC Servo or stepper motor controls.

The stages are equipped with a reference home sensor. RTHM-100 stages can run in continuous or start/stop rotation modes and mounted horizontally or vertically.

These stages feature zero backlash, large 50 mm center aperture and can rotate loads of 20 kg over unlimited rotation angle.

Housed on a high strength aluminum beam and fitted with a stainless steel sealing band, the PSD80 uses Herculane wheels mounted to an adjustable carriage, offering long life and no re-lubrication. Single or multiple carriages on a unit are possible and can handle loads to 500N. A stainless steel lead screw provides actuation with pitch ranges of 4, 15, 25 and 70mm. The 25mm lead is particularly useful in Z axis applications, while the 70mm screw pitch satisfies the higher speed pick and place requirements and allows speeds up to 1 m/s and thrust loads to 300N. The lead screw is available in right and left handed threads and offers smooth, strong and precise actuation. A ball screw can be supplied for applications that require greater positioning accuracy.

PSD80 is supplied as a closed or open format dependent upon the application being subject to the ingress of dirt. The closed unit is rugged, tolerant of debris, and offers many mounting options while the open version is a lower cost solution that is compact, light, and has low friction. Where two units are to be used in parallel, a “slave axis” without the driving screw can be specified for both closed and open units. Adding to its flexibility, the PSD80 is available in a completely corrosion resistant version, as well as a double acting version for applications that require symmetrical movement from opposing carriages.

The first section of the handbook provides insights into the fundamental physical principles involved in linear motion technology, including information about the structural design, operating principles and characteristics of linear motion technology components. Topics such as rolling contact, life expectancy, pre-load, rigidity, accuracy and lubrication are also discussed in detail.

Later sections describe the structural design and technical characteristics of the manufacturer’s linear bushings and shafts, profiled rail systems, ball screw assemblies, and ready-to-install linear motion actuators and Cartesian robots. Readers will also find useful design hints and advice on product selection, assembly and installation, as well as tips for cost-effective project engineering.

The IDEA system is a compact, easy-to-use electronic drive and fully programmable control unit integrated with a linear actuator resulting in a single, compact package. Programming the actuator is though the use of on-screen graphic buttons instead of complicated command sets or other proprietary programming languages. The software allows the system designer to easily troubleshoot programs through line-by-line or multiple line program execution using the interactive debug feature. Inputs and outputs can also be simulated in software before ever connecting actual I/O hardware.

Other features include programmable current control, a single supply voltage of 12 to 48 VDC, 2.6Arms (3.68Apeak) max rated current per phase, and 8 opto-isolated general purpose I/O. The inputs are rated for 5 to 24 VDC, 4mA max per input. The outputs are open collector, 5 to 24 VDC, 200mA maximum per output. To learn more, visit www.idea-drive.com.

iglide G300 bearings are used on each of the crumbler’s eight rolling elements. Grease fittings made the rollers susceptible to dirt build-up, which eventually led to the formation of a thick sludge as the tool sat idle in-between harvests. Fortunately, iglide bearings are lubrication-free and dirt- and dust-resistant and so are ideal for use in this outdoor application. They are also unaffected by rain and any moisture from the soil, thanks to their corrosion-resistant and low moisture absorption properties.

iglide plastic plain bearings are available in 28 different polymers. Every iglide bearing material possesses a number of special features, which makes it suitable for particular applications and requirements. iglide G300 bearings are cost-effective and can be paired with a number of different shafting materials. They are best for rotational and oscillating movements and low to average running speeds. They also possess a low coefficient of friction and high wear-resistance.

With a 5mm air gap between the motors forcer and shaft, users have more flexibility when machining their device to level. It is also a good motion solution when a user does not have the ability or resources to do an accurate alignment of the forcer and the shaft.

The L427 series is an optimal solution in environments where there is the potential for matter to stick to and build up on the shaft. When there is the potential for debris to build up on the shaft, the 5mm air gap will prevent the motor from jamming and will also increase the time required between cleanings.

The L427 features a usable stroke length between 100 and 4,600 millimeters and has a constant force of 110N. The motor’s peak force is 450N, while its force constant is 31(Kf) N/Amps. Other features of the product include a 42.7 mm shaft diameter, a 3.6A continuous current, a 14A peak current, a 10 V/m/s back EMF, and a 3kg forcer weight.

Nippon Pulse’s Linear Shaft Motor has three basic concepts. It is simple, consisting of only a magnetic shaft and a forcer. The motor is also high precision, taking advantage of its ironless make-up to offer zero cogging, while giving complete stiffness. Being non-contact, the shaft motor has a non-critical air-gap that eliminates variation in force over the entire stroke of the device.
