More DC motors on Mars in the 2020 Rover

Maxon motor have supplied DC motor and gearhead combinations for NASA’s fifth Rover mission – the 2020 Mars Rover.

NASA’s Jet Propulsion Laboratory is building a Rover that will travel to Mars in 2020. The purpose of this operation is to collect dozens of soil samples, seal them and leave them on Mars for future pick-up. Nine brushless (flat) pancake DC motors and gearhead combinations from maxon’s standard range – that have been heavily customised to withstand the harsh conditions on Mars – are used in the sample handling arm, specifically developed for this mission.

The sample handling arm moves the containers from station to station within the sampling system. Additional DC motors are also in the Rover and assist with obtaining the samples and sealing the containers. Maxon’s brushless DC motors and gearheads need to survive the powerful entry, descent and landing sequence as well as the harsh daily conditions on Mars with sandstorms and temperatures ranging from -130 to +70ºC.

From the outside, the Mars 2020 rover looks similar to its precursor Curiosity, that is still operating on Mars. The 2020 mission will have several new instruments on board to deliver unique new data. A key objective will be to search Mars for bio-signatures. Another instrument on board will test whether it’s possible to generate oxygen from the atmosphere for possible future human visits. However, the most significant innovation is the ability to take rock samples in several locations and prepare them for return to Earth.

Brushless flat DC motors going to Mars

Brushless motors from maxon motor are again being used by NASA for the Mars 2020 rover.

For critical tasks you need the best quality. The Jet Propulsion Laboratory have selected nine brushless flat motors from maxon motor for the rover which they intend will take soil samples and seal them in containers for future transport to Earth. Various motion applications are performed. Sample tube holding, the robotic arm, container handling, sample gathering and container sealing. 32mm diameter and 20mm diameter flat brushless motors have been combined with heavy duty 22mm planetary gearheads and modified specifically for the Mars mission in close collaboration with JPL for the difficult conditions experienced with descent, landing, sandstorms and the -130 to +70 degree temperatures.

maxon motor looking ahead with confidence.

A look at 2015 performance so far and future direction of the DC drive specialist.

Speaking at the annual press conference, Dr. Karl-Walter Braun (Majority Shareholder of maxon motor ag) and Eugen Elmiger (CEO) revealed that so far, the 2015 financial year revenues increased by 6% totalling more than CHF 400 million for the first time. maxon introduced several new products including the ECX-Speed motors, able to reach speeds up to 120,000 rpm and configurable online. Other new products include the ultra-compact brushless 4mm DC motor with medical approvals, powerful High Torque ECX motors and the EPOS4 positioning controllers.

The new Aerospace division was created “Our highly specialised team solves complex challenges for demanding customers who value extreme reliability in their drives” said Karl-Walter Braun.

The strongest market for maxon remained in Medical technology, industrial automation and robotics and aerospace. maxon DC drives are found in many and varied applications, for example, space missions to Mars, surgical tools or humanoid robots.

Technology and investment in R&D remain a priority. maxon has partnered in several customer projects involving complex system solutions that, in addition to drives, also required software development. “Under this aspect, the ExoMars project by the European Space Agency, which is planning a Mars landing in 2020, is extremely interesting”, said Eugen Elmiger. “This is a very big development challenge.”

Said Karl-Walter Braun, “Our CTO system (configure-to-order and e-shop) provides sales teams and customers with a tool that enables them to configure and order the optimal drive solution for their needs from anywhere in the world.”

With many new products and noteworthy projects, maxon is confident about its outlook for the remainder of the financial year.

Brushless maxon EC motors at the international space station.

maxon EC Drive systems can be found in experimental robots on board the ISS.

The International Space Station (ISS) are testing robots to perform tasks in place of astronauts. One such experiment, called the “Robot Experiment on JEM, or “REX-J”, has been in the Japanese unit of the ISS since 2012. The robot was developed to kick-start a new group of astrobots that can move across the space station, lift loads or perform inspections. Designed to move across a surface like a spider, the REX-J can be operated remotely from the ground control center with no interaction from the ISS crew. There are several brushless maxon EC max motors, planetary gearheads and encoders making up the drive systems in this specialised robot. Full application notes are available on the maxon motor Australia Website.

Unmanned vehicles: the maxon motor drive solution.

Across the many and varied robotics applications be they surgical, UAV, humanoid, collaborative or industrial robots, maxon motor offers motor and drive solutions.

Unmanned robots step-in for humans when the environment is too dangerous or rugged to tread. These robots are designed to perform a variety of tasks, operate independently and negotiate tough terrain. The motors and drives need to be 100% reliable particularly when the environment for repairs is dangerous, impractical or near-impossible for humans to negotiate. Because these microdrives run on batteries, engineers look at the energy efficiency for the longest life-span possible. These drives are configurable on-line to suit specific application needs and ready to be shipped after 11 days.

The maxon motor drive solution

Offering high-energy efficiency, extreme power packed into small spaces, precise position & speed control and very high torque output. The brushed DC motor with planetary gearhead and maxon X-series encoder is pictured below. maxon motor recommends a DCX 22 with graphite brushes for robust operation fitted with a GPX HP gearhead and ENX 16 EASY encoder.

Very small brushless DC Flat motor – in space.

10mm Diameter brushless flat motor supplied by maxon motor Australia with specific customisations for use in space. An example of the extreme miniaturisation possibilities for test, research and exploration robotics.

This brushless DC flat servo motor (commonly referred to in Australia as a pancake motor and globally as a BLDC motor) has an outer diameter of 10mm and a motor length of just 3.25mm. The motor is capable of a top speed of 22000 rpm based on a 4870 rpm/volt constant (KV). Brushless flat motors are characterised by a high torque per volume and normally have low speeds due to a “lever arm” effect, this tiny motor bucks this trend achieving speeds normally only possible from traditionally shaped brushless motors. The motor is available with and without hall sensor feedback to broaden the motor control miniaturisation possibilities.

The emerging swarm robotics trend, miniature spacecraft and micro satellites have an increasing demand for tiny DC motors that implement their gyroscopic effects to orientate the devices. Shown here is a highly customised version that has been adapted for use in outer space. In particular, a vacuum capable lubrication Braycote 601EF has been used in the ball bearings and the shaft has been specifically modified to suit the inertial load.
