8mm Coreless Motor, Coreless DC Motor


Coreless Micro Motor Model NFP-D8620-3665 Data Sheet

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.” For this reason, it is also called ironless. Because there is no iron core to support the windings, they are often held together with epoxy.
