AXIAL MOTOR INCLUDING MAGNETIC LEVITATION ROTATION BODY

WIPO Patent Application WO/2020/138583

A1

Disclosed is an axial motor including a magnetic levitation rotation body. The present invention provides an axial motor comprising: a stator; a magnetic levitation rotation body levitated and rotated with respect to the stator by magnetic force; a first levitation unit for levitating the magnetic levitation rotation body from the stator; and a first rotation unit for rotating the levitated magnetic levitation rotation body. The magnetic levitation rotation body includes a rotor, a second levitation unit disposed to face the first levitation unit side, and a second rotation unit disposed to face the first rotation unit side, wherein the first levitation unit and the first rotation unit are coils that form a magnetic field when electric current is applied thereto or permanent magnets. When the first levitation unit and the first rotation unit are coils, the second levitation unit and the second rotation unit are permanent magnets, and when the first levitation unit and the first rotation unit are permanent magnets, the second levitation unit and the second rotation unit are coils.
