Totally new! Hybrid stepper and PM motor

The Hybrid-PM-Mix (HPM) from Lin Engineering is the first motor of its kind, combining the stator of a hybrid stepper and the rotor of a PM motor in the form factor of a high-speed BLDC. The result is a motor that behaves like a typical high-speed BLDC with the added benefits of hybrid steppers -- precise position control and position holding -- with low noise and vibration too. The 1330 Series is a small motor with a frame size of just 13 mm, which is perfect for small applications with minimal space.

New magnetic tracks for linear motors -- more force with no redesign

The MWD+ is a new family of magnetic tracks from ETEL equipped with stronger magnets. These tracks are compatible with any existing ETEL LMG and LMS linear motor, enabling an average of 15% higher continuous and peak force compared to existing MWD products. Benefits include higher force density per unit volume, which allows users to improve the overall duty cycle or run a given duty cycle at lower temperatures.

Linear robots are now even more versatile

Bosch Rexroth has expanded its portfolio of linear robots (eight different axis combinations with 68 sizes!) for various applications in factory automation. The much wider range of working areas and loads makes the Cartesian subsystems also suitable for applications like battery handling or intralogistics. Predefined axis combinations make for quick and easy sizing and selection. Configure and finalize online and order as preassembled subsystems -- optionally with controllers. Each multi-axis system is also available as a Smart Function Kit for handling or dispensing. Preinstalled software allows for fast commissioning and intuitive programming.

New mini planetary gearmotors

New PH Series Mini Planetary Gearmotors from Applied Motion Products are used with small step motors in NEMA 8, 11, and 14 frame sizes. These gearmotors are used in applications where space is critical. Small motors usually don't produce enough torque for demanding applications. Mini Planetary Gearmotors are an ideal solution. They offer an increase in torque and better inertia matching without breaking the budget.

New cobot welders with extended range unveiled at FABTECH 2022

Universal Robots has grown its welding application segment more than 80% this year as partners develop new capabilities for the pioneering cobot welders. At FABTECH last week, Universal Robots' booth showcased new solutions from Vectis Automation and Hirebotics, enabling the weldment of larger and more complex parts. Attendees also experienced Precision Cobotics' automated MECCO laser-marking solution with Apera AI bin picking, laser welding with Cobot Systems, metal deburring with Kane Robotics, along with the new UR20 cobot in a machine-tending application.
Learn about the new welding options and other UR FABTECH releases.


New! Multi-axis gantry attachment kits extend your working envelope

Multi-axis linear actuator assemblies from Bishop-Wisecarver extend the working envelope of automated motion systems and provide for more complex motion. ECO60 Gantry Kits create reliable and easy-to-assemble connections between ECO60 Linear Actuators. Benefits include: saving design time without sacrificing design freedom, easy ordering with single-part-number kits, and fast and simple assembly and installation. All multi-axis kits are made from aluminum with black anodize and stainless-steel hardware.

Robots handle post processing for metal AM parts and components

The NetShape Robot from Rivelin Robotics provides an automated solution for metal support removal and targeted finishing to meet the standards of mission-critical industries. Driven by the powerful NetShape control software, both machine learning and traditional deterministic control theory are used to optimize the quality and repeatability of the work. The result is an automated support-removal solution that reduces defects by 90%, exhibits a 10-fold reduction in operational costs, and eliminates human risk and variability.

Flat external rotor with encoder

The DF45 brushless DC motors from Nanotec are now available with an integrated encoder. The new flat motors with a diameter of only 45 mm are ideal for applications that require precise positioning in confined spaces such as AGV wheel drives, access control systems, and door drives. The two-channel encoder has a resolution of 1,024 CPR and provides additional Hall signals for commutation. The difference in length between the standard motor and the encoder version is only 2 mm, as the encoder has been completely integrated. The DF45-E has a rated power of 65 W at a rated speed of 4,840 rpm. Custom windings or shafts are also available.

The influence of operating speed on step motor selection

According to the engineers at Lin Engineering, "Frequently, when it comes to step motor selection, users will select a motor with the highest holding torque rating, assuming that it will give them optimal performance. However, it is an improper practice to select a motor based on holding torque alone. In fact, the step motor with the highest holding torque in many situations can prove to be a poor choice -- especially when trying to maximize torque at a desired operating speed."

Extra-Duty Overhung Load Adaptors

Zero-Max has announced three entirely new Extra-Duty Overhung Load Adaptor (OHLA) models (350, 650, 950). The new designs feature a number of carefully chosen upgrades including spherical bearings, enhanced sealing technology, stronger shafts, and a longer profile delivering increased operating life, heavy load capacities, and higher speed ratings. They provide a solid, permanent mounting surface, eliminating premature motor or pump failure due to axial and radial overhung loads on a motor or pump shaft.

Lead-foot police: Ford testing geofencing tech in Europe that automatically reduces vehicle speed

Many cities and towns limit speeds around schools, hospitals, and shopping areas. Seeing the signs, however, can depend on how visible they are, whether they are concealed by branches, or maybe surrounded by a cluster of other signs.

Now, Ford is testing connected vehicle technology using geofencing (a virtual geographical boundary) that could one day do away with the need for speed limit signs completely, as well as potentially making streets safer for other road users and pedestrians. Ford says its Geofencing Speed Limit Control system could help drivers avoid inadvertently incurring speeding fines and improve roadside appearances.

Driver assistance technologies such as Ford's Intelligent Speed Assist and Adaptive Cruise Control with Stop & Go already help ensure drivers do not exceed speed limits. Ford says its Geofencing Speed Limit Control system is potentially more flexible and effective than on-board systems, and could, in the future, be applied to Ford commercial and passenger vehicles.

Researchers are using two Ford Pro vehicles to analyze the impact of speed limiting in terms of improving traffic flow and reducing the risk of accidents. Testing with the all-electric Ford E-Transit vans extends to all 30-km/h zones in the center of Cologne, Germany, as well as in selected 50-km/h and 30-km/h zones elsewhere in the city.

The 12-month trial builds on other recent Ford research projects that aim to help improve road safety, including connected traffic-light tech that could automatically go green to offer clearer routes for ambulances, fire engines, and police vehicles, and the use of specific speakers inside the vehicle to alert drivers to the direction from which people and objects are approaching.

The geofencing trial is the result of a collaboration between the Ford City Engagement team, city officials in Cologne and Aachen, Germany, and Ford software engineers in Palo Alto, CA. Together with colleagues in Aachen, the Palo Alto engineers developed technology that connects the vehicle to the geofencing system for GPS tracking and data exchange.

The driver receives the information via the dashboard display cluster, with the new speed limit flashing below the current speed. The vehicle automatically reduces speed in line with the geofenced zone. The driver can override the system and deactivate the speed limit control at any time.

In the future, Ford's Geofencing Speed Limit Control system could enable drivers to set their own geofencing zones at speeds as low as 20 km/h, including at depots and private facilities. Speed limits could also be set dynamically to take into account local hazards, temporary road works, and the time of day.

The trial in Germany runs until March 2023.
