Sintered Neodymium rotor
Bit random but...
Just wondering what "Sintered Neodymium rotor" actually means in terms of how it affects a motor, i've gathered that it's obviously what the rotor is made out of or partially made out of but i don't know what it does.
I've seen it a few times and i wanted to know if it really does make a difference or is it just a "I'll give it a really cool name to make people think that it's much better"?
Thanks.

Sintered Magnet Rotors: Sintered magnets are a type of ceramic composed of compressed Neodymium-Iron-Boron powder. Sintering involves the compaction of fine alloy powder in a die, and then fusing the powder into a solid material with heat. While the sintered magnets are solid, their physical properties are more similar to a ceramic, and are easily broken and chipped. Sintered NdFeB magnets are generally plated or coated with Nickel-Copper-Nickel plating to prevent corrosion. Nickel-Copper-Nickel plating has excellent corrosion resistance and durability as well as providing a clean and shiny appearance. Magnets used in Novak motors are high-energy 30 MGOe, and high temperature materials.
And, bonded rotors:
Bonded Magnet Rotor: A recent development in magnetic materials is the high-energy polymer bonded magnet. Magnetic powder, namely neodymium-iron-boron (NdFeB), is blended with polymer and injection molded to form complex shapes. A maximum magnetic energy level of 12 MGOe is attainable with bonded magnets. The biggest shortcoming of bonded magnets is the low operating temperatures.
