Several companies around the globe have been hard at work innovating and refining magnet-free electric motors to make them a more viable option for the fast-growing EV industry. ZF Friedrichshafen has ...

The incredible power of electric motors can only be matched by how difficult it is to make them. These things need magnets to work, and magnets are made from rare earth elements, which are difficult ...

In this intriguing video, we dive into the world of creating a free energy generator using simple components like magnets and a motor. Discover the science behind this innovative setup and learn how ...

The electric motors that power today’s EVs rely on permanent magnets made using rare-earth metals such as neodymium. Rare earths are the 15 elements whose atomic numbers run from 57 to 71, plus ...

While electric vehicles certainly offer a host of eco-friendly advantages, they're not without some asterisks, one being the rare earth materials (and harmful mining thereof) used to make the magnets ...

Tesla made a significant change to its electric motor strategy with the introduction of the Model 3, switching from an AC induction motor to a permanent magnet motor. Now, Tesla’s principal motor ...

We recently published an article on the Power Electronics with the headline, “Unique Motor Uses Only Permanent Magnets – No Electric Power Required.” We received a firestorm of criticism that this ...

Closed-loop motor control generally requires sensors that accurately determine the position of the motor rotor to effectively implement communication of the excitation for the windings (an exception ...

A robotic device that can operate inside a medical scanner’s claustrophobic interior could pave the way for MRI-guided surgery 1. Magnetic resonance imaging (MRI) reveals concealed soft tissue so, in ...
