Outer rotor permanent magnet direct current brushless motor and fan applying same

The utility model discloses an outer rotor permanent magnet direct current brushless motor and a fan using the same, relates to the technical field of three-phase direct current brushless motors, and can solve the problem that motor processing, assembling and cost are difficult to reoptimize. The motor comprises a permanent magnet outer rotor, and the permanent magnet outer rotor comprises a permanent magnet ring and a bearing disc which are integrally formed by magnetic plastic, and further comprises a magnetic conductive ring, so that the permanent magnet outer rotor can be used as a part of a motor shell, and is matched with a conventional excitation stator assembly in a manner of coaxially rotating with a middle shaft; therefore, the outer rotor, the middle shaft and the inner stator can be directly assembled to form the motor, a motor shell is omitted, materials, machining and assembling of the motor shell are correspondingly omitted, even magnetic conductive components are omitted, and simplification of
