Coreless / Ironless DC Motors
The wound copper or aluminum core rotates around a magnet without the use of iron. This is done by making a cylinder shape.
Advantage: light and fast to start spinning (used in computer hard drives)
Disadvantage: easily overheats since iron normally acts as a heat sink, it needs a fan to keep cool.
