Brushed DC motor vs Coreless DC motor
A typical brushed DC motor consists of an outer stator, typically made of either a permanent magnet or electromagnetic windings, and an inner rotor made of iron laminations with coil windings. A segmented commutator and brushes control the sequence in which the rotor windings are energized, to produce continuous rotation.
The construction of a coreless DC motor eliminates the laminated iron core of the rotor. In other words, Coreless DC motors have a rotor that is hollow and self-supporting, which reduces mass and inertia. The rotor windings are wound in a skewed, or honeycomb , forming a self-supporting hollow cylinder or basket. Since it has no iron core to support the windings, they are usually held together with epoxy. The stator is made of a rare earth magnet, and placed inside the cylinder. All of the core produces torque and smooths running.
Coreless DC motors are available in brushed and brushless versions. As the name suggests, the difference is whether the brushes are present or not. In the former, the current commutation in the stator windings and changes in magnetic field orientation is provided by brushes and commutator, in the latter they are generated electronically with the rotor position being given by special "hall sensors".
