Electric Motor Magnets

Smaller motors are just as efficient as larger motors that use ferrite magnets.

Electric motor magnets.

The magnetic field for a synchronous machine may be provided by using permanent magnets made of neodymium boron iron samarium cobalt or ferrite on the rotor. In some motors these magnets are mounted with adhesive on the surface of the rotor core such that the magnetic field is radially directed across the air gap.

From the motor that spins a dvd disc to the wheels of a hybrid car neodymium magnets are used throughout the vehicle.

The decision between samarium cobalt or neodymium as a vehicle magnet is usually based on either operating temperature and or corrosion resistance. Advancements in neodymium motor magnet grades have allowed for advancement in motor technology. Neodymium magnets are also used in electric car motor applications. Bentley is developing high performance electric motors that use no rare earth magnets the luxury brand is aiming for a full ev by 2026 with motors that are completely recyclable.
