DEFINITION
Coreless DC motors are a type of DC motor that provides many advantages over traditional iron-core DC motors[1]. They are often used for highly dynamic movements and are ideal for use in robotic applications.

APPLICATION
Coreless DC motors are widely used in industrial automation. They can be used in motor control, RF modules, energy power, etc.[1]
In addition, coreless DC motors can also be used for communication in the Industrial Internet of Things (IIoT). Compared with traditional radio frequency communication, Peta Hertz Communication (PetaCom) has the advantages of high data transmission rate, low latency, and high determinism, so has important application potential in the Industrial Internet of Things. Coreless DC motors can also be used in medical equipment and robotics. In medical equipment, coreless DC motors can be used to control the movement of medical equipment, such as controlling the movement of surgical robots. In robotics, coreless DC motors can be used to control the motion of a robot, such as controlling the joint motion of a robot. In summary, coreless DC motors are motors that are widely used in communications, precision engineering, industrial automation, environmental monitoring, medical equipment, and robotics, and are also used in remote-controlled aircraft and toys. In industrial automation, coreless DC motors can be used in motor control, RF modules, energy power and other fields[2]

CONSTRUCTION
The construction of coreless DC motors provides several advantages over traditional, iron-core DC motors.
First, the elimination of iron significantly reduces the mass and inertia of the rotor, so very rapid acceleration and deceleration rates are possible.
Second, the compact design of coreless DC motors lends itself to applications that require a high power-to-size ratio, with motor sizes typically in the range of 6 mm to 75 mm and power ratings of generally 250 W.
Third, the absence of iron means no iron losses, which makes coreless DC motors more efficient than traditional DC motors[3].

DESIGN
Coreless DC motors have a self-supporting, ironless rotor coil with a skew-wound design. This design provides extremely low rotor inertia, unique dynamics, and precise running. The self-supporting, ironless rotor coil is the central element of every coreless DC motor[4]. Coreless DC motors are also more reliable than traditional DC motors because they have no commutator, which tends to cause electrical and RF noise[5]
