This utility model discloses a lightweight winding structure for a coreless motor, relating to the field of coil windings. The lightweight winding structure includes a coreless winding in the shape of a sleeve. One end of the coreless winding has a front end cover. On the side of the front end cover near the coreless winding, multiple connecting pieces are distributed at equal angular intervals around the axis of the front end cover. This lightweight winding structure achieves precise weight reduction of the front end cover by opening a first lightweight slot at the position directly opposite the end of the coreless winding and a second lightweight slot on the outer edge. This reduces the added mass of the rotor, thereby reducing rotational inertia, decreasing energy consumption during high-frequency start-stop and high-speed rotation, and improving the motor's response speed and power density.
