One year on: maxon supports Emirates Team New Zealand.

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.

Discontinuation of 13mm brushless DC maxon motor.

maxon would like to inform customers of the upcoming discontinuation of the EC 13 and EC size 5 brushless DC motors with a power of 30 W and 50 W.

The discontinuation affects the following motors and combinations in which they are used:

  • EC 13, 30 W Length: 39 mm
  • EC 13, 50 W Length: 50 mm
  • EC size 5, 30 W Length: 39 mm
  • EC size 5, 50 W Length: 50 mm

The sterilisable versions of these EC motors with a diameter of 13mm / 0.5” were first introduced in 2009. They were revised in 2013 and at the same time, the status of the original version was set to NRND (not recommended for new designs).

With the release of the latest generation ECX SPEED 13 brushless motors in April 2017 (main picture), all EC 13 / size 5 motors with 30 W and 50 W were set to NRND.

The ECX SPEED 13 brushless motors serve as a replacement for the EC 13 / size 5. They are also available in a sterilisable version (up to 2,000 autoclave cycles) and are very similar in terms of both performance specifications and size.

The ECX 13 can be combined with gearheads of the GPX 13 (sterilisable) and GPX 14 series, are available with integrated EASY INT encoders, and cost less than the EC 13 / size 5.

As configurable units, ECX SPEED 13mm brushless motors are also available for shipping within 11 days.

Burling and Tuke on top of the world again.

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.

Roger Frigola from Emirates Team New Zealand inspires maxon.

Roger Frigola, Optimisation Engineer at Emirates Team New Zealand, presented to the maxon global Group at their annual management meeting in Brunnen, Switzerland on the 18 September, 2019.

maxon Group were delighted to welcome Roger Frigola (MSc Aerospace Engineering and PhD Artificial Intelligence) from Emirates Team New Zealand at their annual management meeting. In their capacity as Official Supplier to Emirates Team New Zealand, maxon Group received insight into the process and technicalities of designing the AC75 Class yacht. For the current America’s Cup campaign, the design process began in 2018 with the publication of the Class Rule that states specific design parameters set out by the Deed of Gift. Roger has been involved in the America’s Cup since 2014 and has experience in the McLaren F1, Ferrari F1, Porsche Le Mans and Red Bull F1 Motorsports.

Emirates Team New Zealand: Current Defenders of the America’s Cup

The America’s Cup is the world’s oldest trophy in international sport, captivating the world since its inception in 1851. Emirates Team New Zealand are three times winner, current Defenders of the America’s Cup and the first non-American competitor to successfully defend the trophy. It would appear to remain that if you won the America’s Cup you would stay with the same type of boat. This isn’t the case for Emirates Team New Zealand, who created a New Class of Yacht – the AC75. Innovation is key and the entire concept was proven only through use of a simulator without any prototypes. The Challengers have developed smaller boats and tested them, but Emirates Team New Zealand placed their trust in the simulation and the team of people working behind the scenes.

For the new AC75 Class of Yacht, Emirates Team New Zealand designed the system that all the teams use to raise and lower the foils. The Design & Engineering Team also work with HP using 3-D printed components for the Yacht.

The team

A support team of more than 150 people contribute expertise from across many disciplines. There is the crew of 11 sailors (8 of those are grinders) and around 25 people within the design and engineering team including naval architects, structural and mechanical engineers, simulators and software developers. Then there is the shore people, boat builders, marketing, media, lawyers, accounting, physiotherapists, trainers and cooks.

AC36: a new rule

One method of gathering data for the performance of the Yacht and the Sailors was to test through physical experiments in wind tunnels or towing tanks. However this America’s Cup campaign is the first to prohibit any experimental testing in wind tunnels or towing tanks. This new concept and Yacht design has been modelled on physics with design by optimisation. The results of the simulation data were then compared to the actual boat reactions with testing on and off the water looking closely at safety issues, strains, stress loads etc. The Computational fluid dynamics (the examination of fluid flow in accordance with its physical properties such as velocity, pressure, temperature, density and viscosity) were modelled on the conditions of a wind tunnel. The amount of data that is collected is so large it’s stored across 8 HP desktop machines.

The members of the Design & Engineering Team spend the majority of their time on the Chase Boat, analysing real-time data from the AC75 yacht test runs. The thousands of gigabytes per day that are captured are compared against the computational physics from the simulation data and used in the build of the second boat that will sail in the America’s Cup.

The America’s Cup World Series, Sardinia, April 2020

All teams will meet for the first time between April 23-26, 2020 with the America’s Cup World Series kicking off in Cagliari, Sardinia. The fearlessness with adopting innovation and confidence placed in the simulation, combined with the knowledge, skills and enthusiasm of Emirates Team New Zealand – not to mention the backing from Sponsors, Official Suppliers and Supporters – advocate strongly the retention of Current Defender of the America’s Cup. The prowess of the AC75’s will be on full display and we eagerly await seeing the boat racing to its full potential.
