    Abstract: The present invention relates to a variable-flux motor comprising: a stator having stator coils; and a rotor disposed to be rotatable with respect to the stator with an air gap interposed therebetween, wherein the rotor comprises: a rotor core; a fixed magnet disposed along the radial direction of the rotor core, and of which one end portion is disposed adjacently to the air gap; and a variable magnet disposed inside the fixed magnet along the radial direction of the rotor core, and the variable magnet is formed such that a magnetic flux thereof varies when a preset current is applied to the stator coils. Therefore, use of an expensive permanent magnet can be excluded.

    Abstract: 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.
