It’s been one year since maxon jumped onboard as an Official Supplier to Emirates Team New Zealand.
maxon are proud to have been working closely with Emirates Team New Zealand’s design and engineering team for more than one year providing advice on integrated drive solutions. Looking back a lot has happened in this short time. The team led the way in innovation, designing the system that all the teams use to raise and lower the foils, and pushed the boundaries of technology to build the new concept AC75 yacht using only simulation and not prototypes for testing. With work underway on the second AC75, Emirates Team New Zealand’s spirit for continuous improvement and blue-sky thinking aligns with maxon’s passion and motivation to excel in technology. maxon was excited to see Te Aihe gliding over the water on a recent test run. The AC75 is constantly pushing the boundaries of technology with the use of maxon DC motors and drive systems.
maxon Group Australian Managing Director Brett Motum said “our DC motors are perfectly suited for wherever extreme precision and the highest quality standards are necessary and where compromises cannot be tolerated. The motors selected have high power density and they are configured to operate under intense conditions”. The America’s Cup AC75 Class Rule allows the use of electric motors to operate hydraulic valves, drive clutches, rudders and foils. Teams may also use motors for driving simulator platforms and numerous test jigs.
Te Aihe is currently en-route to Cagliari, Sardinia, for the first America’s Cup World Series (ACWS) event in April where all the AC75s will race against each other for the first time. In the absence of Te Aihe the team finally revealed their test boat which was about a year behind the other teams. This was a strategic and considered decision. The reveal of Te Kāhu at this late stage in the campaign allowed development alongside the first AC75 to wholesomely contribute in the construction of the next AC75. Te Kāhu allows the sailors to continue training in a model that as close as possible mirrors the first AC75. You’ve heard slow and steady wins the race. Now watch this space.

In February, Solar Orbiter will launch its mission to collect new data about the Sun. Swiss research and industry have played a substantial role in the construction of the space probe – with drives from maxon Group among the contributions.
The European Space Agency (ESA) wants to study the Sun up close. Next month the agency will launch the Solar Orbiter space probe, equipped with ten measuring instruments. Scientists hope that the mission, which will last several years, will provide them with new insights into phenomena such as the solar wind, as well as the complex dynamics that are responsible for solar eruptions. Solar Orbiter will fly to within 45 million kilometres of the Sun – closer than Mercury, its nearest planet. At this distance, the side of the probe facing the Sun will be exposed to intense heat: more than 500°C. A heat shield will protect the important instruments on board the probe, equipped with shutters to provide a view of the Sun only when measurements are being taken.
Studying solar eruptions
The same applies to the spectrometer-telescope for imaging X-rays (STIX), whose purpose is to study solar eruptions more closely, possibly enabling large-scale eruptions to be predicted in future. STIX was developed at the University of Applied Sciences and Arts Northwestern Switzerland (FHNW) in collaboration with several industrial partners from Switzerland, including Almatech. Swiss drives made by maxon are among the components used in the X-ray telescope. Two specially modified DC motors with diameters of 13 mm move an aluminium attenuator, which slides in front of STIX’s 30 detectors as required. The micro drives are wired in parallel and can be used together or individually. Thus ensuring that they’ll run smoothly for the entire five years planned for the mission. The design is based on micromotors that will soon be used in ESA’s ExoMars Rover. Key factors when selecting the drives were their low weight, energy efficiency, and resistance to vibration.
Solar Orbiter is one of ESA’s flagship projects and has cost more than 1.5 billion Australian dollars (AUD). After its planned launch in February, the probe will journey for almost two years before it can start taking measurements. The mission is scheduled to end in 2025.
From the Sun to Mars
While Solar Orbiter approaches its launch date, preparations are underway for the next two major Mars projects, which are scheduled to start in the (European) summer of 2020: NASA’s Mars2020 Rover and ESA’s ExoMars Rover. The aim of both missions is to provide new information about the Red Planet, answering questions such as whether there has ever been life on Mars. Mars2020 also carries a small helicopter to deliver a proof of concept that flights are possible on Mars despite the very thin atmosphere.
maxon drives are used for mission-critical tasks in both projects, including wheel drives, handling soil samples, and steering the Mars helicopter.

After 5 days of racing in their home waters in Auckland Peter Burling and Blair Tuke won their fifth 49er World Championship.
A difficult week for the fleets racing at the 49er Worlds due to mixed sailing conditions and a tense last day for Peter Burling and Blair Tuke that started with a gear failure causing them to pull out of the opening race, followed by a third place in the next race.
At the start of the medal race Burling and Tuke were eight points clear, needing to finish within four places of the second placed German team also intent on winning the championship. The drama peaked when Peter Burling slipped off the back of the boat and into the water when tacking on the first upwind leg of the medal race, plunging the New Zealand pair to the back of the fleet.
The Kiwi – duo though fought their way back to finish fourth in the Medal Race and to win the gold medal by six points overall.
“It’s definitely the top, no doubt,” Tuke said when reflecting on a fifth world title. “We said going into it that racing a world champs on your home waters would be right up there with the Olympics. It feels pretty good.
“It always feels good when you do it in that fashion, when it comes down to the wire as well. We would have liked to have won by more but you take it any way you can. We’re really proud that we came back in the end there.”
“It was a bit annoying,” an understated Burling said of his swim in the medal race. “It was the same thing we did in the first race when we snapped the tiller extension. It was really choppy out there and hard to get the timing quite right.”
Tuke added: “It certainly wasn’t part of the plan. We would have ideally sailed a bit better in the morning and wrapped it up but, whichever way we get it, we’re pretty happy and we knew that if it came down to this we would be able to step up. To do it in front of our friends, family and supporters is very, very special.”
Peter Burling and Blair Tuke have an intense schedule ahead as they will combine their Olympic campaign with their America’s Cup commitments.
With little time to reflect on today’s win, tomorrow they’ll be back at work with Emirates Team New Zealand sailing the teams AC75 back on the very same waters of their latest world beating accomplishment.
maxon Group is an Official Supplier to Emirates Team New Zealand. We follow the progress of their journey as Defender in the 36th America’s Cup campaign, March 2021.

maxon Groups current edition of driven, the in-house magazine that explores drive technology, focuses on the impact digitisation and automisation have on the workplace, and what exactly is meant by a Smart Factory.
Home automation systems where appliances are managed remotely and through a single touchpoint, are becoming more commonplace and a great example of digitisation in the home. In companies though, how will Industry 4.0, the Internet of Things and artificial intelligence affect employment? Will people be replaced by automisation and robotic systems? Readers will learn what is behind the terms used in connection with the smart factory and why some technologies are taking longer to reach fruition than initially expected.
In other news, the editorial staff of driven visited an exoskeleton team preparing for the Cybathlon, the second part to the article on “Inductance in iron-core DC motors” is released and the Ceramic Department within maxon Group gets a closer look.

Produced entirely in-house, maxon Group Australia designed and delivered a complete solution on a system that sensed, and measured, the subjective perception of pressure.
maxon have long been involved in assisting customers with the selection of their DC motors and drive systems within haptic applications. The obvious involvement of maxon is support in selecting the appropriate DC motor and controller. It is perhaps not a traditional connection that maxon be involved in the development of a device from concept stage through to the creation of the algorithms to gather data and provide valid haptic feedback. maxon Australia R&D team led by Dr Carlos Bacigalupo created such a device in-house and all in one mechanism.
Macquarie University Australia PhD candidate David McNaughton initially contacted maxon in July 2018 for assistance with DC motor selection. David needed to build a sensitive test instrument as part of his PhD thesis. After many communications with maxon application engineers, David realised there was no better candidate to build complex motorised instrumentation than the motor manufacturers themselves.
David said “It became quickly apparent in the discussions with maxon that the skills and knowledge to build such a device required a high level of specialisation. After meeting with the application engineers, I was confident they could deliver this bespoke device in a timely manner. maxon were professional and detail orientated throughout the developmental stages of the device, which led to the device meeting brief specifications. The goal of this research is to understand important perceptual and sensory processes involved in the human body. maxon’s insights to improve the device compared to previous models has been crucial in making this possible”.
Complex force control
The aim of the instrument was to produce adjustable levels of force to the finger of a test subject. The forces needed to be generated in three specific methods. Each of these methods requires a specific behaviour from the motor controller. Either by being idle, directly targeted or manually controlled by a slider, the instrument had to comply with well defined experimental protocols.
Four different target forces were required for David’s tests. 1N, 1.5N, 2N and 2.5N and the forces needed to be randomly selectable and quickly applied by the operator. All test data needed to be recorded for later analysis.
There were three main considerations to the application:
- the DC motor and controller to switch between manual or automatic operation;
- the need to produce adjustable levels of force;
- real time recording and translation of data into meaningful language for analysis.
Of the many motors considered for the force application the maxon Rare Earth 50mm, 200W was selected because of its linear characteristics, detent free, coreless rhombic winding design, proportionally low mass inertia and a high torque constant of 242mNm/A allowing for extremely fine control over the applied pressure.

Coupled with the motor was an optical encoder with 20,000 quad count resolution for feedback to the maxon EPOS 4 motion controller. Dr Carlos Bacigalupo said “Carefully selected gain adjustments and a well-tuned PID feedback loop are required for this type of sensitivity. The configuration and testing cycle is greatly accelerated by the powerful tuning wizards in the EPOS Studio, but it is also vital to have the ability to individually manage all necessary parameters within the controller’s object dictionary”. maxon provided a colour touch screen for operator interface, with custom quick set controls and overriding fine adjustment facilities. The test data is recorded to a USB stick.
maxon: expertise is beyond motors
maxon have supplied many motors to customers who develop their own systems. Being involved from the concept to the finalised product was an exciting step. “maxon Australia quickly became interested in the project and showed no hesitation in an ability to deliver” said David. “Their professionalism, in depth knowledge and enthusiasm to build the device were significant factors toward awarding the contract to Maxon. The design, construction and programming of this bespoke device would not be possible without the knowledge and expertise of maxon application engineers.”
maxon are excited to bring ideas to fruition and turn concepts into reality. This is a unique project that will have far reaching gains beyond helping David to achieve results for his PhD.

Drive specialist maxon and Swiss car racer Sébastien Buemi team up to share their passion for precision, efficiency and e-mobility.
Racer Sébastien Buemi knows what precision and efficiency are. After all, the former F1 driver has already won 13 races in the new Formula E and was the world champion in 2016. Being fast is not enough to be a front runner in this fully electric race series, a driver must also be efficient and energetic, or the battery will be empty before he reaches the finish line. That’s why Sébastien Buemi is a perfect match for maxon, whose high-end electric motors can be found not just in Mars rovers, but also in the Ad-Blue injection systems used in Formula 1 race cars.
maxon is collaborating with Sébastien Buemi and the parties signed the contract on September 9th. To celebrate the occasion, Buemi visited maxon headquarters in Sachslen, Switzerland to tour the company and meet the maxon team. Buemi was impressed with the cleanrooms and the tiny drives with a diameter of only four millimeters.
When the Formula E starts its sixth season on November 22nd, the Swiss collaboration will be represented by the maxon logo on Buemi’s racing suit. Buemi is also an ambassador for maxon. He says: “I’m proud of working with a Swiss high-tech company and being part of the maxon family.” The joy is mutual. CEO Eugen Elmiger says, “Sébastien and the Formula E in general are a great match for maxon. After all, we are increasingly becoming a systems provider, and the e-mobility market is particularly interesting in this regard.”

The latest issue of maxon’s driven magazine looks at developments and trends in e-mobility.
50 years ago, it wouldn’t have been dreamed of that a family could go on a trip in their car without burning a drop of fuel. Or that inexperienced cyclists could tour vast mountain ranges. Or that robots pull weeds, not humans. These are three, of many, examples that show the influence of electric drive systems on our daily lives and our mobility.
In addition to e-mobility developments, readers get an insight into the battery development at maxon and meet a friendly superhero with a disability. For inquisitive minds, there is an in-depth technical article about inductance in iron-core DC motors.
