Abstract:
A motor comprising an HALBACH array and an apparatus comprising the same. The motor comprises an assembly of a stator (10) and a rotor (20), the stator (10) and the rotor (20) are disposed opposing to each other to form a plurality of tooth (11, 21) and slot (12, 22) structures. The motor further comprises a plurality of HALBACH arrays of permanent magnet units (30) distributed in the plurality of slots (12, 22) of the stator (10) and/or the rotor (20). The motor of the present application has the plurality of HALBACH arrays of permanent magnet units respectively distributed in the slots of the stator and/or the rotor to form a simple arrangement of a HALBACH array, and therefore the present application has increased torque density of the motor and reduced production cost, facilitates mass production of permanent magnets, and is easy to install and not easy to damage.
