This month, NASA will be sending its fifth rover to Mars. Its main mission is to collect soil samples that will be analyzed on Earth at a later time. The rover will also carry a helicopter that will perform the first flights on the Red Planet. maxon’s precision dc and brushless dc motors will be […]
What is a gated index pulse for incremental encoders?
Incremental encoders typically use two square-wave signals in quadrature (out of phase by 90 degrees) to track position and direction of motion. But because they only track incremental position (not absolute position) they’re not able to determine the true position of the motor and connected equipment after a shut-down or power loss. So most incremental […]
Power over Ethernet (PoE) and M12 connectors in motion designs
Though the internet of things is most visible to laymen in consumer devices, the IIoT is massive. The majority of applications are in business, factory, and healthcare settings … and more than a third of the nearly $6 trillion IoT market is in manufacturing. Connectivity is the basis of all this IIoT — providing the […]
Balancing power, weight, and efficiency objectives with low-power braking
Engineers who want the smallest, lightest, lowest power brake available should talk to their brake supplier in the earliest stages of the design project. Waiting until later in the process will trigger a compromise on one or all three of these important design considerations. By Brian Mather | Industrial product manager • Ogura Industrial Corp. […]
KEB America debuts high capacity spring-set load brakes
KEB America’s new High Capacity Load brakes use a spring-set (power-off) design and are electrically released. The brakes are offered in graduated sizes up to 3,200 Nm (2,360 ft-lb). “These brakes are ideal for critical lifting applications that require secondary braking, including cranes, hoists, and lifts”, notes KEB Marketing Manager, Jonathan Bullick. The brakes feature […]
What do bit rate, baud, and cycle time mean in industrial networks?
For industrial networks, two of the most important performance factors are determinism and speed. In other words, industrial networks must be able to deliver data in a specified, predictable period of time, and they need to do so as quickly as possible. When describing network speed, three specifications are typically used: bit rate, baud, and cycle […]
WITTENSTEIN releases new NPL-W corrosion-resistant gearbox
WITTENSTEIN alpha, a provider of high-precision servo gearboxes and drive systems, has launched a new corrosion resistant gearbox to support the increasing market demand for components that can withstand processing, overspray and cleaning environments. Ideal for food processing, bottling and packaging machines, NPL-W features a painted, corrosion resistant housing with no gaps, depressions, undercuts, dead […]
What is Ecolab certification for automation components?
In applications that involve wet or humid environments — especially those in the food and beverage industry — a component’s IP (International Protection) rating for ingress of dust and water is an important factor in its selection. But even if a component is rated as dust-proof and protected against the forceful water jets used during washdown […]
Planetary gearboxes with fitted pinion from Neugart
Neugart is extending its portfolio of planetary gearboxes, especially for rack and pinion drives, with an additional option for a fitted pinion from its in-house production. Two specific types of pinion are available: the PK1 pinion is fitted to the toothed output shaft of the gearbox, whereby the secure connection that is required is provided […]
What are Hiperface and Hiperface DSL?
Position feedback is core to any servo application, and most rotary servo motors employ an integrated feedback device with a physical link back to the servo drive, allowing the drive to read the motor’s position and correct any errors between the commanded and actual positions. Two interfaces that facilitate the communication between the motor feedback […]
