摘要： Provided is a fan motor applied to a fridge and providing a driving power for circulating cold air within a storage space. The fan motor includes a stator including a stator core. The stator core includes a yoke, a plurality of teeth, and a plurality of slots each formed by two teeth adjacent to each other and the yoke positioned between the two teeth. A first interval between an internal central point of the stator core and an inner circumferential surface of the yoke at a tooth portion is greater than a second interval between the internal central point of the stator core and an inner circumferential surface of the yoke at a central part of the slot in a circumferential direction thereof. A space factor can be effectively increased and efficiency of the fan motor can be improved without increasing the size of an external diameter of the stator.

摘要： Disclosed herein are a brake device of an in-wheel motor and an in-wheel motor including the same. The brake device of an in-wheel motor includes a brake drum part fixed to one surface of a rim of an in-wheel motor and having at least one hole, and at least one pin pushing/pulling driver installed inside the brake drum part in a radial direction thereof and configured to push or pull a pin, which is insertable into the hole according to an input of a braking signal of the in-wheel motor, toward or from the hole. The brake drum part includes a disc body having a hollow and an outer wall, wherein a shaft of the in-wheel motor is disposed to pass through the hollow and the outer wall is fixed to the rim, and a circumferential protrusion protruding a predetermined length in a direction spaced apart from the disc body to the rim and having the hole in the circumferential protrusion. When the braking signal is input, a braking force is rapidly applied to the in-wheel motor, and also the braking force is constantly maintained using a mechanical mechanism even when a supply of electric power is cut off on an inclined road and the like such that safety can be improved.
