Abstract: According to an embodiment of the present disclosure, provided is a high-output, high-torque in-wheel motor having a power line-taken-out structure. According to an embodiment of the present disclosure, the in-wheel motor includes a circular rim; a shaft connected to the rim through a center of the rim; a motor assembly including a stator connected to the shaft in the rim and a rotor surrounding the stator and rotated about the stator; a cover coupled to an opening of the rim to block the motor assembly from an outside of the rim; and a bearing contacting and configured to support the shaft. The shaft includes a first shaft body passing through a center of each of the rim and the cover and extending outward; and a second shaft body having a larger diameter than a diameter of the first shaft body and disposed between the stator and the bearing. A power line for supplying power to the motor assembly is inserted in a radial direction of the second shaft body between the stator and the bearing and is taken out in a longitudinal direction of the second shaft body. According to an embodiment of the present disclosure, even when a diameter of the power line is increased to achieve the high-output, high torque performance of the in-wheel motor, structural rigidity of the shaft may not be degraded.
