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

Motion Control – Application – Maxon drives on the Red Planet!

In July, NASA sent 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 also carried a helicopter that is performing flights on the Red Planet. maxon’s precision DC and BLDC motors are used for numerous mission-critical tasks.

motion control - maxon motorTaunton, 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 – Harmonic Drive FHA-C Mini 24V Servo Actuator with Dual Absolute Encoder and Panel Mount connectors!

Motion Control – Harmonic Drive  Servo Actuator

motion control harmonic drive servo actuator

 


motion control - electromateVaughan, Ontario, Canada — Motion Control Components — Introducing Dual Absolute encoder versions of the FHA-C mini actuator. Featuring BiSS-C Harmonic Drive fha-24v-002bi-directional communication for both encoders. The dual encoders are incorporated in essentially the same package size as the long-standing FHA-C mini single incremental encoder version. Without increasing the size, the dual absolute encoder offers single turn absolute position at the output, without the need for battery back-up. Panel mount connectors come standard, and customers can choose between 4 exit options.

The FHA-C mini Series is a family of extremely compact actuators that deliver high torque with exceptional accuracy and repeatability. The actuator combines a high precision Harmonic Drive® gear component with a pancake brushless servo motor. A single turn 14 bit (16384 cpr) gear output encoder has been integrated along with a single turn 14 bit (16384 cpr) motor input encoder providing a true absolute encoder that does not require a battery within 360° of rotation of the output. Typical multi-turn encoders monitoring the motor input shaft require a battery to store the current position when power is lost to the system; however, the dual absolute encoder overcomes this need. In other words, No Battery Required. When power is restored the actuator knows its position.

Features include:

  • Zero backlash
  • Incremental, Absolute or Dual Absolute Encoder
  • 24VDC winding
  • High-torque/weight and torque/volume ratio
  • Optional flex-rated cables with sealed connectors

Motion Control – Long Travel and High Torque Rotary Voice Coil Actuators from H2W Technologies!

Motion Control – High Torque Rotary Voice Coil Actuators

motion control rotary voice coil actuator


motion control- h2w

 

 

 

The Voice coil motor requires 1.7 amps of continuous current per coil and 5.1 amps of peak current per coil to generate the specified forces.  The actuator fits in and envelope of 10.26 in [260.5 mm] x 3.01 in[76.4 mm] x 3.39 in [86 mm].  The moving coil design ensures a hysteresis free movement as the coil is wet wound and self-supported, and the non-commutated coil allows for ripple-free motion and no cogging.  The voice coil actuator has been designed with mounting provisions in the magnet and coil assemblies.  This allows for the integration of a bearing system to maintain the clearances between the coil and permanent magnetic field assemblies. The rotary voice coil actuator is ideal for applications requiring high torque and high- speed applications. Examples of such applications are driving a gimbal axis in scanning applications as well as providing stabilizing torques for image stabilization. More examples of H2W’s Rotary Voice Coils are available on our website: https://www.h2wtech.com/category/rotary-voicecoil-actuatorsSanta Clarita, CA — Motion Control – H2W Technologies has developed several high torque rotary voice coil actuators, otherwise known as a limited angle torque motors or LATs. The model TWR-034-800-1RC was designed to allow for a relatively low moving mass and inertia, as well as a long rotary stroke of 34 degrees [0.59 radians] on a 11.4” [290 mm] arm, which equates to a travel of 6.75 inches [171.5 mm] which is long travel for this style of actuator, which typically restrained to an equivalent linear travel of 2 inches [50.8 mm]. This rotary voice coil actuator can generate a continuous torque of 1400 in-oz [9.8 N-m] and a peak torque of 4200 in-oz [29 N-m] at a duty cycle of 10% (i.e. 1 second on, and 9 seconds off) in each coil on a 11.4 inch [290 mm] rotation arm.  The TWR-034-800-1RC has a total angular displacement of  34 degrees [0.59 radians] and a motor constant of 275 in-oz/sqrt(watt) [1.92 N-m/sqrt(watt)].
