ZF Makes Magnet-Free Electric Motor Uniquely Compact and Competitive

ZF has developed an electric motor which does not require magnets. In contrast to the magnet-free concepts of so-called separately excited synchronous motors (SESM) already available today, ZF’s I2SM (In-Rotor Inductive-Excited Synchronous Motor) transmits the energy for the magnetic field via an inductive exciter inside the rotor shaft. This makes the motor uniquely compact with maximum power and torque density. […]

Cyclic Materials Raises $27M to Scale Recycling Technology, Links up with Solvay and Arnold 

Creating a Circular Supply Chain for Rare Earth Elements and Critical Materials 

Cyclic Materials, a Canadian advanced metals recycling company focused on producing critical materials, today announced it has raised $27 million in an oversubscribed Series A financing. The money is flowing in quickly after accomplishing its first production run of rare earth magnetic material and forging a string of partnerships with magnetics industry notables. These include chemicals giant Solvay which is planning to build a major rare earths magnet operation in Europe, and Arnold Magnetic Technologies (see related article), among others. […]
