A motor comprising a HALBACH array and an apparatus comprising the motor, the motor including an assembly of a stator and a rotator, a plurality of tooth structures and groove structures are formed on the opposite surfaces of the stator and the rotator. The motor further includes a plurality of HALBACH array permanent magnet units distributed in the plurality of grooves of the stator and/or the rotator. By using the above motor, the plurality of HALBACH array permanent magnet units are respectively distributed in the grooves of the stator and/or the rotator to form a simple HALBACH array arrangement, therefore the torque density of the motor can be improved, the mass production of the permanent magnet can be facilitated, the production cost can be reduced, and the installation can be facilitated and not easily damaged.
