New power-off brakes for parking brake applications
The MPC is a power-off brake module with an output shaft. The unit mounts directly onto a NEMA C-Face servo or stepper motor, and the output can also be coupled to a NEMA C-Face gear reducer. This brake is designed to decelerate or hold an inertial load when the voltage is turned off. When voltage is applied, the friction disc is released, and the brake is free of torque. This power-off brake is best suited for parking brake applications used to hold a load in position, and is ideal for creating brake motor packages for small servo and stepper NEMA 17 or NEMA 23 frame motors. Available from Servo2Go.

This integral gearmotor combines Bodine's high-performance type 22B brushless DC motor with the new 60P (60-mm) planetary gearhead. It is ideal for applications that require higher torque than conventional helical/spur gearheads of a similar size can provide, and where a very low backlash gearhead is not required. Typical applications include conveyors, pumps, packaging, industrial automation, and a wide range of solar- or battery-powered equipment.
Compact brushless DC servo motor with integrated controller
Nanotec has developed the compact PD2-C-IP, a brushless DC servo motor with integrated controller and 42-mm flange size for use in harsh environmental conditions (class IP65). The PD2-C-IP is available as a brushless DC motor, with an operating voltage of 12 V to 48 V and a rated power of 105 W, and as a stepper motor with a nominal torque up to 0.5 Nm. Due to the field-oriented control based on an integrated encoder, both motors are controlled in the same way and differ only in their working point. Each motor is available in a USB or CANopen version. They offer effective and economical drive solutions when high precision and maximum benefit are required.

High-torque rotary voice coil actuators
H2W Technologies has developed several high-torque rotary voice coil actuators, otherwise known as a limited angle torque motors (LATs). The model TWR-015-346-2RC was designed to allow for a low moving mass (68 grams per coil) and inertia, as well as dual independent coils to allow for two independent motion profiles or couple the coils together to double the torque output. This rotary voice coil actuator can generate a continuous torque of 185 in.-oz (1.29 Nm) and a peak torque of 555 in.-oz (3.88 Nm) at a duty cycle of 10% (i.e., 1 sec on and 9 sec off) in each coil on a 4-in. (102-mm) rotation arm. By coupling the coils, the continuous torque doubles. Applications include driving a gimbal axis in scanning applications and providing stabilizing torques for image stabilization.

First engine assembled for DARPA and Boeing reusable experimental spaceplane
Aerojet Rocketdyne technicians complete final assembly on the first AR-22 rocket engine, shown at its facility located at Stennis Space Center. The engine was built for Boeing as part of the U.S. Defense Advanced Research Projects Agency Experimental Spaceplane program.
Aerojet Rocketdyne has completed assembly of its first AR-22 rocket engine built for Boeing as part of the U.S. Defense Advanced Research Projects Agency (DARPA) Experimental Spaceplane program. This new Boeing spaceplane, called Phantom Express, is intended to demonstrate a new paradigm for more routine, responsive and affordable space access.
Aerojet Rocketdyne's AR-22 engine, derived from the Space Shuttle Main Engine that was designed from the outset for reusability, is the main propulsion for Phantom Express. The fuel is Liquid hydrogen.
DARPA is collaborating with Boeing to fund development of the Experimental Spaceplane (XS-1) program. Once Phantom Express reaches the edge of space, it would deploy the second stage and return to Earth. It would then land on a runway to be prepared for its next flight by applying operation and maintenance principles similar to modern aircraft. [Boeing rendering]
"Phantom Express builds on our legacy of reusable space flight experience to provide the ability to quickly augment and replace on-orbit capabilities, which face an increasing array of threats from potential adversaries," said Eileen Drake, Aerojet Rocketdyne CEO and president. "Our immediate task is to demonstrate this rapid turnaround capability for this engine on the ground, paving the way for a demonstration program."
The AR-22 engine is capable of generating about 375,000 lb (170,097 kg) of thrust and was designed to fly 55 missions with service every 10 missions. This reusability feature makes the AR-22 ideally suited for Phantom Express.

This new Boeing spaceplane, called Phantom Express, is intended to demonstrate a new paradigm for more routine, responsive and affordable space access.
The reusable, 100-ft-long Phantom Express spaceplane will take off vertically and land horizontally. The 24-ft-high vehicle will be equipped with an expendable second stage capable of placing up to 3,000 lb (1,361 kg) of payload into low Earth orbit. The spaceplace has a wing span of 62 ft.
"The aircraft-like operations of Phantom Express are an important factor in the rapid turnaround of this spaceplane," said AR-22 Program Manager Jeff Haynes. "Additionally, the engine has a hinged nacelle that makes it easier to access and inspect the engines for rapid turnaround."
Aerojet Rocketdyne assembled the AR-22 at its facility at NASA's Stennis Space Center in Mississippi. The engine will undergo a series of daily hot-fire tests at Stennis starting this summer to demonstrate its ability to support the high flight rates envisioned for Phantom Express. These tests will also provide valuable insight that will be used to refine Phantom Express flight and turnaround procedures, while also informing the design requirements for the new ground infrastructure that Boeing is developing for the flight program.
