High-Performance Custom Magnetic Rotors for Efficient Motors

The magnetic rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor's axis.

They usually feature high-strength Neodymium-Iron-Boron (NdFeB) for standard environments, Hard Ferrite for low-cost needs, or Samarium Cobalt (SmCo) for sub-sea or high-temperature operations.

Magnets can be made by placing a magnetic material, such as iron or steel, in a strong magnetic field. Permanent, temporary, and electromagnets can be produced in this manner. The atoms forming materials that can be easily magnetized such as iron, steel, nickel, and cobalt are arranged in small units, called domains. Each domain, although microscopic in size, contains millions of billions of atoms and each domain acts like a small magnet. If a magnetic material is placed in a strong magnetic fi

Attract certain materials, such as iron, nickel, cobalt, certain steels and other alloys. Exert an attractive or repulsive force on other magnets (opposite poles attract, like poles repel). Have an effect on electrical conductors when the magnet and conductor are moving in relation to each other.

Modern magnet materials are made through casting, pressing and sintering, compression bonding, injection molding, extruding, or calendaring processes. Once manufactured, magnets often need to be further processed by grinding or other machining processes, and then assembled into a next level assembly.
