Patent ID: 10910964

Abstract:
A laundry treatment apparatus is disclosed. The laundry treatment apparatus includes a cabinet (100) defining the appearance of the laundry treatment apparatus, a drum (300) rotatably disposed in the cabinet (100), and a drive unit (400) for rotating the drum (300), wherein the drive unit (400) includes a first drive unit (410) for generating rotational force required to rotate the drum (300), and a second drive unit (430) for changing the ratio of rotational force generated by the first drive unit (410) and rotational force transferred to the drum (300), wherein the first drive unit (410) includes a first stator (411) for generating rotating magnetic fields, a magnetic flux converter (413) rotatably disposed radially outside the first stator (411) to change the magnetic flux of the magnetic fields generated by the first stator (411), and a first rotor (415) disposed radially outside the magnetic flux converter (413) and rotatable by the magnetic fields, wherein the magnetic flux converter (413) is configured to rotate with the second drive unit (430).
