Description
Coreless DC motors do away with the laminated iron core in the rotor. Instead, the rotor windings are wound in a skewed, or honeycomb, fashion to form a self-supporting hollow cylinder or “basket.” Because there is no iron core to support the windings, they are often held together with epoxy. The stator is made of a rare earth magnet, such as Neodymium, AlNiCo (aluminum-nickel-cobalt), or SmCo (samarium-cobalt), and sits inside the coreless rotor.
