Rotary Assembly Unit

The SCHUNK SRU-mini- Speed rotary unit from SCHUNK (Morrisville, NC) is available in two model sizes and provides swivel times from 0.27s. If lightweight parts are handled with the unit, more than 4,000 cycles per hour can be achieved. Model size 10 achieves swivel times of 0.27s, and up to 3,600 cycles per hour is possible. As an alternative to higher speeds and number of cycles, higher load capacities can be implemented with an unchanged installation space. As part of a patented damping design, elastomer has been combined with an oil-damped shock absorber.

Choosing the Right Drive Technology

Coming up with the right drive technology for an application often depends on the options available. Here are five of the most common drive configurations being used today, along with their benefits and drawbacks. Although there are a number of variations of drive technologies for motion applications, there are a few that are used for the majority of systems being built today. These most common drives do take a bit of understanding before applying.

Reasons for Turning to Slotless DC Motor Technology

When first introduced, brushless DC motors, despite their many advantages, were cast as a costly alternative to brush-commutated motors, and were typically only specified for low-power applications where long life was the primary desired requirement. Without the mechanical brush-commutator mechanism that would wear and eventually result in motor failure, brushless motors could be relied upon to deliver performance over time. As for other advantages, conventional wisdom held that brushless motors provide high speed and fast acceleration, generate less audible noise and electromagnetic interference, and require low maintenance. Brush-commutated motors, on the other hand, would afford smooth operation and greater economy.

Motion Solutions for Electric Expansion Valves

Expansion valves are flow-restricting devices present in any refrigeration system. The valve needle remains open during steady state of operation. The size of the opening, or position of the needle, is related to the pressure and temperature of the evaporator. When set and controlled properly, an expansion valve will keep the evaporator active throughout its operation.

Hamburg Airport Relies on Drive Technology to Keep Bags Moving

Hamburg Airport in Germany handles nine million pieces of baggage every year. For the baggage handling staff, the reliability of the conveyor system and the prevention of faults are the highest priorities. The breakdown of even a single component of the system would result in a backlog and unacceptable delays.

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.
