Coreless DC motors do away with the laminated iron core in the rotor, and a stationary high performance toroidal magnet makes up the core of the motor. The motor windings are still attached to the motor shaft but are laid up in a resin moulding that rotates around the magnetic core. Because there is no iron core to support the windings, they are often held together with epoxy. A coreless DC motor is a type of DC motor that has a unique design in which the rotor does not have a ferromagnetic core, unlike conventional DC motors. Coreless DC motors have a low inertia design, which allows them to rapidly accelerate, stop, and change direction with ease, making them ideal for applications requiring high-speed and precision control.

Firstly, the efficiency of the motor is higher because magnetic losses are lower. Secondly, since the windings (the part that heats up under load) are closer to the motor case, they can radiate unwanted heat better and therefore deliver higher power. These two points make the coreless motor enables higher performance.

High-quality Coreless motors offer higher performance at a higher cost than iron core motors, so the coreless dc motors typically used for highly miniaturized and high-performance applications, but lower volume industrial, instrument and medical applications.

Mini coreless DC motors are compact and lightweight devices that offer high performance and efficiency. These motors are commonly used in various industries for their unique characteristics and capabilities. Mini coreless DC motors find applications in robotics, drones, wearable devices, and medical equipment. They provide smooth and precise rotational motion, making them ideal for applications such as camera gimbals, prosthetic limbs, smartwatches, and miniature robots.
