World's highest force voice coil actuator

H2W Technologies has developed the world’s highest force commercially available non-commutated DC linear actuator, otherwise known as a direct drive voice coil actuator. The model NCC08-75-3000-3X is capable of generating a continuous force of 300 lb (1330 N) and a peak force of 900 lb (4000 N) at a duty cycle of 10% (i.e., 1 sec on and 9 sec off). A moving mass of just under 8 lb (3.6 kg) allows for a maximum theoretical continuous acceleration of nearly 38 Gs.

Fast and compact direct-drive micro-positioning stages

Precision motion and nanoposi-tioning leader PI (Physik Instrumente) delivers a family of compact linear and rotary stages driven by ceramic direct-drive motors. The patented ultrasonic motors provide smooth motion with high resolution and a high dynamic range. The self-clamping motor principle locks the stage into place, devoid of creep, once a target position has been reached. This intrinsic brake-like behavior comes at no extra cost and provides advantages that are not available with classic electro-magnetic drive technologies. Two linear stages with 18-mm and 22-mm travel are available, as well as an XY stage providing 22 mm x 22 mm. Several encoder options are standard. Applications include medical devices, optical instrumentation, photonics alignment, and super-resolution microscopy.

Selection tips for rodless electromechanical and electric rod actuators

When you specify a linear actuator, some basic decisions come first. Do you go with electric or fluid-powered? Do you need the push/pull of an electric rod actuator or the load-carrying action of a rodless electromechanical actuator? Aaron Dietrich from Tolomatic may have your answer. Dietrich has compiled some very good tips for selecting these actuator types.

Extreme force electric linear actuator controls lumber drying

The lumber processing industry demands rugged, strong, reliable, and accurate equipment in all its operations. Conditions can be harsh. Hydraulic cylinders have been the go-to, but they have limitations, such as inconsistent control, leaks, temperature sensitivity, maintenance requirements, and lack of feedback. Now there are electric rod actuators powered by roller screws that can meet the requirements of these high-force applications.

Medium-load hexapod 6-axis motion platform

With the usability of 6-axis hexapods increasing in research and industry applications, PI introduces a new medium-load 6-axis precision motion platform, the H-825 hexapod. The H-825 provides a self-locking load capacity up to 30 kg (66 lb). The motion range is up to 55 mm (linear) and up to 38 degrees (rotation). High system precision is guaranteed by absolute encoders and an actuator resolution of 8 nanometers -- with excellent position repeatability of +/-0.1 µm and +/-2 µrad, respectively. The parallel-kinematic design of the hexapod makes it smaller and stiffer than traditional 6-axis positioning systems while providing a higher dynamic range. Features long-lifetime brushless servo motors.

Sci-fi spinner: BAE Systems engineers unveil futuristic UAV concept that uses both fixed- and rotary-wing flight

The BAE Systems Adaptable UAV concept melds fixed- and rotary-wing flight technologies.

 

 

Within the next few decades, armed forces could be using unmanned aerial vehicles (UAVs) with adaptable aircraft technologies that alternate between fixed- and rotary-wing flight.

Engineers from BAE Systems, together with students from Cranfield University (Bedfordshire, U.K.), have revealed a new technology concept -- named Adaptable UAVs -- that can alternate between the two different flight modes in the same mission. When in rotary-wing mode, the UAVs can be launched and recovered from battlefields and docked on a special pole.

The Adaptable UAVs are a hybrid between fixed- and rotary-wing aircraft, and would use adaptive flight control and advanced navigation and guidance software, which would allow the aircraft to benefit from the greater speed and range afforded to fixed-wing aircraft, before alternating to rotary-wing mode to hover and achieve vertical takeoff and landing. This novel technology could allow UAVs to better adapt to evolving future battlefield situations and through working together in a swarm, tackle sophisticated air defenses, as well as operate in complex and cluttered urban environments.

In the rotary-wing mode of flight, the Adaptable UAVs can be easily and safely launched and recovered using a range of vehicles in dangerous environments that might be cluttered by personnel, other aircraft, or vehicles. The pole constrains the lateral or sideways movement of the UAV when being launched or recovered, so strong winds cannot dislodge them. This also avoids any damage to personnel nearby. This is particularly important when recovering a UAV to the aft of a ship or a land vehicle. The pole's gyro-stabilized element also ensures that it remains upright independently of the host vehicle's orientation, which may be rolling if on a ship, or in the case of a land vehicle driving up or down a slope at the time of the launch or recovery.

VIDEO: Like something right out of "Star Wars," the BAE Systems' Adaptable UAV concept is great to watch in action.

"The battlefield of the future will require novel solutions to meet emerging threats and to keep human operators safe wherever they may be," said Professor Nick Colosimo, BAE Systems' Futurist and Technologist. "The Adaptable UAVs concept and related technologies are one of a number of concepts being explored through close collaboration between industry and students in academia."

Cranfield University is one of BAE Systems Strategic University Partners. Research staff and students have explored a range of UAV technologies including research into adaptive flight control and advanced navigation and guidance software.
