The latest episode of “Die Horn” podcast discusses the various types of electric motors and their essential components, such as rare earths. The hosts delve into the technical differences between synchronous and asynchronous motors, as well as permanent magnet and external excitation in the rotor.
Interestingly, many manufacturers are looking to move away from neodymium-boron permanent magnets, as China produces 95% of them, making it a raw material monopoly. Instead, they are relying on external excitation, which can be more efficient than a permanent magnet synchronous machine (PSM) due to its flexible control of the rotor’s magnetic field.
In an opening credits segment, Clemens discusses his struggles with brake judder on his KTM 690 Duke R, seeking tips from listeners. Meanwhile, Sebastian talks about his experience driving on the racetrack with his Honda Fireblade SC44, which he purchased at a low cost compared to a car.
Listeners are invited to share their thoughts and tips on the topics discussed through the show’s Whatsapp answering machine at +49 2694 3190211.
