Abstract
Provided herein is a fan motor including a rotating shaft, a stator including hole in which the rotating shaft is disposed, a rotor disposed outside the stator, a fan coupled to the rotating shaft, and a housing in which the stator and the rotor is disposed, wherein the rotor includes a yoke and a first magnet coupled to the yoke, and the fan motor further includes a magnetic fluid disposed between the first magnet and the stator. The magnetic fluid is filled in a gap between the stator and the magnet of the rotor and keeps the inside of the motor airtight, thereby having an advantageous effect of preventing introduction of salt water or foreign substances into the motor.
Claims18
A fan motor comprising:
- a rotating shaft;
- a stator including a hole in which the rotating shaft is disposed;
- a rotor disposed outside the stator;
- a fan coupled to the rotating shaft;
- and
- a housing in which the stator and the rotor are disposed,
- wherein the rotor includes a yoke and a first magnet coupled to the yoke,
- the fan motor further comprising a magnetic fluid disposed between the first magnet and the stator,
- wherein the magnetic fluid is disposed on a lower end of the first magnet, and
- wherein the yoke includes a scattering preventer which extends by being bent from a lower end of the yoke toward the rotating shaft.
A fan motor comprising:
- a rotating shaft;
- a stator including a hole in which the rotating shaft is disposed;
- a rotor disposed outside the stator;
- a fan coupled to the rotating shaft;
- and
- a housing in which the stator and the rotor are disposed, wherein:
- the rotor includes a yoke and a first magnet coupled to the yoke;
- and
- a second magnet is disposed in at least one of the fan or the housing,
- the fan motor further comprising a magnetic fluid disposed on the second magnet,
- wherein the housing further includes a scattering preventer protruding from a bottom surface toward the rotating shaft, and
- wherein the scattering preventer is disposed between the outside of the fan and the second magnet in the radial direction at the center of the rotation axis.
A vehicle comprising a fan motor, the fan motor comprising:
- a rotating shaft;
- a stator including a hole in which the rotating shaft is disposed;
- a rotor disposed outside the stator;
- a fan coupled to the rotating shaft;
- and
- a housing in which the stator and the rotor are disposed,
- wherein the rotor includes a yoke and a first magnet coupled to the yoke,
- the fan motor further comprising a magnetic fluid disposed between the first magnet and the stator,
- wherein the magnetic fluid is disposed on a lower end of the first magnet, and
- wherein the yoke includes a scattering preventer which extends by being bent from a lower end of the yoke toward the rotating shaft.
