A permanent magnet outer rotor hoist is disclosed, including a main shaft fixed on the ground; a stator fixed on the main shaft; a roller encircling the main shaft from a circumferential direction of the main shaft and rotating relative to the main shaft; permanent magnets disposed on an inner wall of the roller and distributed along a circumferential direction of the inner wall of the roller, wherein the permanent magnets are uniformly distributed on the inner wall of the roller in a matrix form; and permanent magnet fixing blocks for limiting loosening of permanent magnets, wherein the permanent magnet fixing blocks include first fixing blocks for limiting permanent magnets from a circumferential direction and second fixing blocks for limiting permanent magnets from an axial direction, and the first fixing blocks and the second fixing blocks are orthogonal. The permanent magnet outer rotor hoist has higher safety and reliability.
