Abstract
The present invention provides a fan motor which includes a housing, a stator disposed inside the housing, a rotor disposed inside the stator, a blade coupled to the rotor, and a printed circuit board disposed under the blade, wherein the printed circuit board includes a first mounting portion positioned inside a radius of the blade and a second mounting portion positioned outside the radius of the blade, and in which a component having a large height is mounted on the second mounting portion. Therefore, an advantageous effect that a component having a large height may be mounted within a limited design height.
Claims7
A fan motor comprising:
- a housing;
- a stator disposed inside the housing;
- a rotor disposed inside the stator;
- a blade coupled to the rotor;
- and
- a printed circuit board disposed under the blade, wherein the printed circuit board includes:
- a first mounting portion positioned inside a radius of the blade, and
- a second mounting portion positioned outside the radius of the blade,
- wherein the housing includes an upper housing and a lower housing,
- wherein the stator, the rotor, and the blade are disposed inside the upper housing and the lower housing,
- wherein the printed circuit board is disposed outside the lower housing,
- wherein a board coupling portion to which the printed circuit board is coupled is concavely formed at a lower outer surface of the lower housing, and the first mounting portion of the printed circuit board is coupled to the board coupling portion,
- wherein the second mounting portion of the printed circuit board is exposed to the outside of the lower housing, and
- wherein the upper housing including a board cover to cover the second mounting portion of the exposed area of the printed circuit board,
- wherein the printed circuit board includes a bottom surface that is exposed to outside of the fan motor.
