A New Generation of Axial Flux EV Motors | designnews

There is another way, which is loosely based on a design that Nicola Tesla researched and patented in 1889. An axial flux motor places the permanent magnets on the face of the rotor, and puts the stator in front of the rotor. To balance the magnetic forces, two rotors are often used—one on either side of the stator.

Superconducting magnet - Wikipedia

A superconducting magnet is an electromagnet made from coils of superconducting wire.They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire has no electrical resistance and therefore can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce greater magnetic .
