Motion Control – Maxon drives are heading to the Red Planet with NASA’s Perseverance Rover!

Motion Control – Application – Maxon drives heading to the Red Planet!

In July, 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 BLDC motors will be used for numerous mission-critical tasks.

Taunton, MA — Motion Control Products & Application – maxon drive systems are very familiar with Mars. Our drives have been used in virtually every successful robotic mission over the last three decades. There are now more than 100 of them on the Red Planet and there are likely to be more soon. The launch window for NASA’s next mission opens on July 22nd. An Atlas V rocket will launch the new Perseverance rover on its way to Mars, where it will be searching for signs of previous life on the planet. Its most important job is to take multiple soil samples, seal them in containers and deposit them on the surface of Mars so that a future mission can return them to Earth. Several maxon motors will be used to handle the samples inside the rover. For example, maxon DC motors are installed in the robotic arm, which moves the samples from station to station. Maxon motors will also be used for sealing and depositing the sample containers.

NASA’s Jet Propulsion Laboratory (JPL), is carrying out the mission, and have asked maxon to produce 10 drives for the rover. As with almost all previous Mars missions, these drives are based on standard products from maxon’s catalog with modifications. For the first time, NASA is using brushless DC motors, including: nine EC 32 flat and one EC 20 flat in combination with a GP 22 UP planetary gearhead. Working closely with JPL specialists, maxon engineers developed the drives over several years and tested them thoroughly to achieve the highest standards of quality. “We’ve learned a lot from this exciting project,” says Robin Phillips, head of the maxon SpaceLab. “We now have very broad expertise in space applications and have established quality assurance processes that meet the expectations of the industry. Customers from other industries such as the medical sector, where requirements are often similar, can also benefit from this know-how.”  Space missions place the highest demands on drive systems. This includes vibrations during the rocket launch, vacuum during the journey, impacts on landing, and the harsh conditions on the surface of Mars, where temperatures fluctuate between -125 and +20 degrees Celsius and dust penetrates everywhere

Maxon DC motors control the Mars helicopter.

The Perseverance rover is expected to land on Mars on February 18, 2021 – but it won’t be alone. A drone helicopter called Ingenuity will be attached to the underside of the rover. It weighs 1.8 kilograms, is solar powered and will perform several short flights, as well as take aerial images. The main goal of this experiment is to test the concept for further drones of this kind. maxon has six brushed DCX motors with a diameter of 10 millimeters controlling the tilt of the rotor blades and the direction of flight. The drives are very light, dynamic and highly energy-efficient. These properties are crucial, because every gram counts on the Mars helicopter. Flying on Mars is not easy. The atmosphere is extremely thin, roughly comparable to the conditions on Earth at an altitude of 30 kilometers. The drone helicopter has flown in a simulated test environment in the JPL laboratory. Whether it will lift off on Mars remains to be seen. First, other obstacles, such as the rocket launch, must be successful. “We hope that everything goes well and that we’ll soon see our drives in action on Mars,” says maxon CEO Eugen Elmiger. “We’re all keeping our fingers crossed.”

Motion Control – Lower Cost Moving Magnet Designs from H2W Technologies!

Santa Clarita, CA —– Typically a Motion Control H2W Moving Magnet Actuator has precision bushings and shaft which cause the moving magnet design to be cost prohibitive. However not every customer requires a bushing with high tolerance precision, and thus H2W has the ability to modify the linear bearing systems of our voice coil designs to accommodate a lower cost bushing and shaft. The pictured actuator has a custom shaft and housing to accommodate a customer’s specific cost, envelope, and shaft requirements

Voice Coil Actuators are typically for applications requiring short strokes, however, H2W offers varying strokes from their stock actuators and can modify any of these models with a short lead time to accommodate many specification modifications. Additionally, typically voice coil actuators have been intended for low force applications, however H2W Technologies offers forces up to and exceeding 100 pounds of continuous force and 300 pounds of peak force at 10% Duty Cycle.

The moving magnet style actuator is provided with supplied internal bushings and a hardened steel shaft or hard anodized aluminum shaft. H2W currently stocks actuators up to 3 inches of stroke, and has built moving magnet actuators with a stroke as long as 5 inches, and up to 12 inches can be built upon request.

The NCM10-14-028-2BX is an example of one our lower cost moving magnet motor designs. – Click here for additional information.

Motion Control – New Nanoprecision Linear Shaft Motor Stage Is Available from Servo2Go!

Motion Nanoprecision Linear Shaft Motor

Greenville, DE –— Nippon Pulse America introduces their new SCR100 stage. The SCR100 stage is an ultra high precision, compact single axis stage that integrates a slide guide, encoder, and Linear Shaft Motor. The SCR100 stage offers a wide range of advantages for ultra high performance and accuracy applications. The Linear Shaft Motor is a coreless direct drive linear motor, which has zero cogging. This allows for higher resolution, speed, and continuous force than standard stepper motors and piezo servomotors.

The SCR100 stage is a moving magnet design, which locates all cables and connectors in the stationary base. The resulting absence of any moving cable is clean and compact and eliminates motion errors due to cable forces. The precision ground cross roller way provides high stiffness and smooth motion. Together they are capable of supporting higher torque levels due to offset loads with travels from 50mm to 300mm. The non-contact Linear Shaft Motor and optical linear encoders are self-contained inside the stage, making it a low-profile compact solution. The built-in non-contact optical linear encoder is available with resolutions from 1 micron to 10 nanometers with digital output. The sub-micron resolution results in a high accuracy stage, which is laser tested for optimum performance.

Users of the SCR100 stage in the Drive industry have stated – “This little Nippon Shaft motor stage really performs exceptionally well with both repeatability and coggless velocity control. We are excited by what we see.” While engineers from the Microscopy industry have stated – “The stage is very responsive and does a very good job controlling velocity which is the heart of our process.” Jeramé Chamberlain Linear Shaft Motor product manager for the US states that “With bi-directional repeatability of +/-1 count it rivals all piezo servomotor stages at a fraction of the cost.”

The Nippon Pulse Linear Shaft Motor has gained a reputation of servicing the very demanding, ultra high precision motion control applications in a number of markets. Those markets include Metrology, Spectroscopy, Digital pathology, Microscopy, Disk drive, Semiconductor fabrication, Biomedical, Pharmaceutical, Life Sciences, Cell Imaging, Particle Analysis, Medical Device, Stent fabrication, National Laboratories, Photonics/Telecom, Aerospace and Defense and Genomics.

The SCR100 stage has the added benefit that any standard digital servo driver can drive the SCR100 stage. Any two SCR stages will bolt directly together to form a very stiff, compact X-Y stage. Two SCR stages can be supplied compounded as an X-Y stage to insure true orthogonal orientation. The SCR100-50, with 100-nanometer resolution, has a list price of $3395 US. Options include DI Water or Vacuum compatible, open frame, and custom configurations.
