Abstract: The present invention relates to an in-wheel motor driving apparatus for reducing weight, improving Hall sensor assembly performance, and reducing a defect rate. According to one embodiment of the present invention, the weight of an in-wheel motor can be reduced by separating a suspension housing and a shaft and applying different materials thereto. Furthermore, the ease of assembling a Hall sensor can be improved, and the defect rate can be reduced.

Abstract: A motor for a laundry apparatus includes a stator and a rotor including a rotor frame which rotates outside the stator. The rotor frame includes a base frame having a circular shape and disposed with a distance from a coil, an extension frame which fixes a magnet, an air inlet which suctions air, and a blade protruding to a set height from the base frame, and the blade is positioned outside a region in which the coil is disposed. According to the present disclosure, the heat dissipation performance of the motor can be improved while maintaining the strength of the rotor frame, and motor output can be improved by sufficiently securing a winding space of the coil.

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.
