What Motor(s) will the Cybertruck use?

[TruckElectric]

To call it a reluctance motor suggests that the majority of the torque it produces is reluctance torque and that's not the case here.

Ok got it. I see the difference now.

"A PMaSynRM machine is an interior permanent magnet (IPM) machine [15], [31], [38], [88], [94], [95], [96], [101], [114] and [139], however, in this machine the nature of the produced torque is more based on the reluctance properties of the machine than on the PM properties."

You did just fine. Since this is a quote from a Doctoral Thesis by Reza - Rajabi Moghaddam, he needed to be eloquent.

Since we were on the discussion about Permanent Magnent - Assisted Synchronous Reluctance Machines here is an interesting use for them.

First a little info about it.

EDITRON is the world’s most sophisticated electric drivetrain system designed, manufactured and delivered by Danfoss Editron.

Our unique approach delivers maximum efficiencies, reduced size and weight, plus continual improvements for our customers. The sophisticated software behind our system controls and optimizes each individual component of an electric or hybrid drivetrain, leading to more intelligent management of power distribution.

The EDITRON system is comprised of components designed in-house with high IP-classes. In the marine market, it uses synchronous reluctance assisted permanent magnet technology on machines up to 6MW, while in off-highway and on-highway industries the power ranges from 30kW to 1000kW.

Danfoss is using it to power a Superyacht.


Danfoss Editron delivering hybrid propulsion system for new superyacht

Hybrid propulsion system

• Superyachts emit over 300,000 tons of CO2 annually, a figure similar to or even higher than the emissions produced by entire countries.
• Danfoss Editron’s hybrid marine system produces less noise, saves on space and weight, lowers fuel consumption and reduces emissions.
• Bering 145 will be the first superyacht in Bering Yachts’ fleet and is expected to be ready for delivery to its owner in 2022.

ANTALYA, TURKEY – Danfoss Editron has been selected to provide the hybrid drivetrain system for the Bering 145 superyacht, the new flagship model of Bering Yachts’ fleet. It is expected that the transoceanic model, which will feature some of the latest electrification and yachting technology, will be ready for delivery to its owner in 2022.

Bering Yachts designs and builds semi-custom steel expedition yachts and luxury steel trawler yachts ranging from 15-45m in size. As Bering Yachts’ first superyacht, the model will become the flagship of the company's fleet. The 45m model will feature a master bedroom and a further five guestrooms, quarters for the 12-person captain and crew, as well as dedicated dining, entertainment and lounge areas.

Danfoss Editron is working with Marinel, its system integrator in Turkey, on the project. Marinel is an electrical consulting company that specializes in the design and application of shipboard power distribution and automation systems. Danfoss Editron’s system will contain power take-off and power take-in machines, converters, grid solutions for the AC network and DC/DC solutions connected to the yacht’s batteries, all of which will operate via a DC-cabinet and be controlled by the electronic control system. The system will be configured so that the energy flow can go to and be taken from all directions, such as from the generator and motor to the grid or from the grid to the yacht’s batteries.

When operating in hybrid mode, Bering 145 will have a range of over 12,000 miles at an average cruising speed of 9 knots and be capable of docking and mooring. With reduced noise, space and weight savings and lower fuel consumption, Danfoss Editron’s hybrid marine system will offer smooth operation and an overall improved passenger experience to Bering 145’s owners once delivered.

According to research published last year, there are 300 superyachts currently operating globally. Collectively, these emit over 300,000 tons of CO2 emissions annually, a figure similar to emissions produced by the entire country of Burundi and even higher than other nations, such as Liechtenstein. It is expected that the hybrid Bering 145 superyacht will save approximately 33 tons of CO2 compared to a similar diesel-powered alternative.

Commenting on the project, Danfoss Editron’s Director, Marine business line, Erno Tenhunen, said:

“Our compact electric motors offer high efficiencies, previously only seen in electric vehicles, to the marine propulsion market. Our electric propulsion motor product portfolio now goes up to 6MW, meaning that we can electrify larger ships and vessels than ever before.”

Alexey Mikhailov, President of Bering Yachts, commented:

“We chose to work with Danfoss Editron because of the company’s sophisticated technology, which is compact, lightweight and highly efficient. It was essential for our customer that the company we selected to provide the yacht’s hybrid system had worldwide recognition and proven reliability, which Danfoss Editron does. We firmly believe that our first experience of working with the company will be pleasant and enjoyable and are already looking forward to working together on new projects in the near future.”

Marinel‘s Managing Director Özgür Akay added:

“With the electric and hybrid drivetrain systems provided by Danfoss Editron, we provide our customers with solutions that fully meet their needs.”

Also some automotive applications.

ON Semiconductor to Provide Danfoss with High Power Devices for Inverter Traction Modules

12” Fab enables scale and a secure supply for automotive applications
PCIM Digital Days - FRANKFURT, Germany – 6 July, 2020 – ON Semiconductor (Nasdaq: ON), driving energy efficient innovations, and Danfoss A/S today announced that ON Semiconductor will supply Danfoss Silicon Power with high power IGBTs and diodes for inverter traction modules in the fast growing electric vehicle market.

As a leading supplier of power semiconductors for more than 50 years, ON Semiconductor has developed a wide range of automotive components, by applying advanced technology and extensive R&D expertise, in the fields of high-voltage interfacing, smart power management, in-vehicle networking, system level integration, and sensor interfaces. The company also provides a robust set of modeling tools that enable the designer to realize application performance in simulation rather than costly measurement cycles. In addition, utilizing the 12 inch Fab in East Fishkill, ON Semiconductor is perfectly positioned to supply competitive devices at a scale necessary to serve the vehicle electrification market for years to come.

Danfoss Silicon Power is a subsidiary of the Danfoss Group, the largest industrial company in Denmark. For decades, Danfoss Silicon Power has been helping top tier manufacturers and system suppliers meet stringent reliability, design and cost targets by designing, developing and manufacturing customized power modules for automotive, industrial and renewable applications.
