Abstract
A rotor for a motor is proposed, the rotor including: a magnet coupled to a shaft to surround an outer surface of the shaft and having opposite-polar magnetic portions circumferentially alternately arranged; a first fixed ring fixed to the shaft to surround an outer surface of the shaft, disposed in contact with an upper portion of the magnet, and having a first coupling portion at a lower end being in contact with a top of the magnet to prevent rotation relative to the magnet; and a second fixed ring fixed to the shaft to surround the outer surface of the shaft, disposed in contact with a lower portion of the magnet, and having a second coupling portion at an upper end being in contact with a bottom of the magnet to prevent rotation relative to the magnet.
