    Highly Efficient Magnet-Free Electric Motor Developed by MAHLE of Stuttgart Germany

      MAHLE offers an electric motor with advantages not combined in any other motor of this type by any other vendor or auto OEM to date.

    Permanent magnets made using rare-earth metals is what currently drives the electric auto motors. These rare-earth metals are 15 elements that run the periodic table from 57 to 71 including yttrium and scandium which are soft silvery-white heavy metals. Very destructive to the environment and almost entirely controlled by China, but used in a wide range of electronics from computers, cell phones to current electric/hyrid auto's. Not much in the electronic industry is not using some rare-earth metals.

    MAHLE under the guidance of Dr. Martin Berger, MAHLE Vice President for Corporate Research and Advanced Engineering has stated that the MAHLE breakthrough shows that the New Generation of Traction Motors is the best way forward for a cleaner planet. MAHLE traction motor does not require the rare-earth magnets for a magnetic field generation but instead uses an excitation coil located in the rotor to do the same job. As a result, the MAHLE traction motor is rare-earth material free reducing the impact on the earth and over all society while also making it much cheaper to produce these motors.

    Wireless inductive power transmission which this motor uses inside allows for contact-free parts which has no friction allowing for no wear and long life. Inductive motors have now overcome the durability question which was critical in the past. Efficiency of the technology is boosted by current advanced digital control systems.

    As per Dr. Berger, "To get energy to the rotor, it uses an alternating field which is then converted into direct current for the magnet coils. These magnet coils replace the permanent magnets. They induce a magnetic field into the air gap and causes the motor to generate torque."

    This new traction motor is able to achieve 96 plus percent efficiency according to MAHLE. Eliminating exposure to fluctuating costs of the expensive materials and any ethical concerns with having to rely on a material supply that is controlled by China.

    Per MAHLE this new traction motor allows a major step towards sustainable mobility while helping to minimize the impact on the planet.

    Better yet is that these motors are maintenance-free while being suitable for a wide range of applications.

    definitely would change my value on electrics by eliminating the rare earth magnets.   So this came out awhile back, why has there been little press on this.

    I wonder who they might get to use these new engines. Considering they announced to the world on May 5th 2021, I kind of think they should have an oem lined up, but they have been quiet. Record sales in China though.

    • Since online stories seem to change, I am copy and pasting the instructions here: Uninstall the Copilot app The first thing you should do is uninstall the Copilot app. This is a Windows app and can be uninstalled like any other Windows app. There are a few ways to do this, and we’ll outline two of them. The fast way Hit the Windows Key to open your search and type in Copilot. Right-click the app with your mouse and select Uninstall. A window will pop up asking you to confirm. Do so. The app will be uninstalled. The harder way Open the Settings on your Windows PC. Navigate to Apps and then Installed apps. Find Copilot on your list of installed apps. Click the three-dot button on the right side and click Uninstall. For all intents and purposes, Copilot will cease to function on your PC after uninstalling the app, and you can go about your life in peace. Disable Copilot on a Windows PC Once the official app is uninstalled, there’s no real reason to do anything further, but if you really hate AI, you can if you want to. Damn the man! In the interest of completeness, here’s how to disable Copilot on your PC. This method is doable in two ways. If you have Windows 11 Pro, you can do this through the Group Policy Editor, which is quite simple. Those who have Windows 11 Home have to go through the Registry Editor, which can be an intimidating and potentially dangerous process. Thus, proceed at your own risk. Disable Copilot through the Group Policy Editor Hit the Windows Key to open search and type in Edit group policy or gpedit.msc and open the setting that pops up. Once the Group Policy Editor is open, you’ll navigate to a setting in the left margin. The order is User configuration, then Administrative templates, click on Windows components, and then finally Windows Copilot. Double-click where it says Turn off Windows Copilot; a new window will open. In the window, click Enabled, then Apply, and then finally OK. Copilot will be disabled. This method only works for Windows 11 Pro and Enterprise. While it is possible to install and use Group Policy Editor on Windows 11 Home, it’s not worth the effort, as there's a better option: Disable Copilot through the Registry Editor Hit the Windows Key and type in regedit, and then open the Registry Editor. Navigate to HKEY_Current_User, then Software, then Policies. Once there, go to Microsoft and then Windows, and finally CurrentVersion. There, you’ll see an option called WindowsCopilot. Double-click the TurnOffWindowsCopilot and change the value from 0 to 1. Exit Registry Editor and reboot your PC. It’s a simple enough process if you're used to working in the Windows 11 backend, but you can mess up a lot of stuff in the Registry Editor if you're not. Thus, again, proceed with caution and don’t change any of the other values. In addition, not all versions of Windows will have this registry option. Voila, Copilot is as off as Copilot gets If you've followed our advice, Copilot will now be disabled (or uninstalled) on your Windows laptop or Chromebook. Since most of its functionality comes directly through the Copilot app, uninstalling the app gets you about 90 percent of the way there, which should be more than enough for most Windows users. Disabling it via the Group Policy Editor or the Registry Editor finishes the job, but without the app in the front, Copilot can’t really do much of anything anyway.
