Rotor for maximizing air-gap magnetic flux in slotless motor and slotless motor including the same

摘要

The present invention discloses a rotor for maximizing air gap magnetic flux of a slotless motor and a slotless motor including the same. According to the present invention, a magnet receiving portion including a core portion into which a rotation shaft is inserted, a rib forming an outer circumferential surface spaced apart from the core portion by a predetermined distance, and a plurality of wedges extending from the core portion to the rib, the core portion, the rib, and Including a permanent magnet disposed in a plurality of divided spaces formed by the wedge, wherein the permanent magnet is an N-pole permanent magnet disposed in a part of the plurality of divided spaces, and the rest of the plurality of divided spaces A rotor of a slotless electric motor including a S-pole permanent magnet and a plurality of Halbach-arranged permanent magnets disposed between the N-pole permanent magnet and the S-pole permanent magnet are provided.
