The gas circuit design, that is, the stator steel sheet and the winding wire, is mainly located in the housing space of the housing, and the motor stator is provided with a plurality of independent seconds around the housing space. The steel sheet, each of which is provided with a coil, has an arc-shaped pole shoe facing the center of the casing, and a motor rotor is disposed on the inner side of the solitary pole shoe provided in the motor stator ring row, and the rotor connection is provided with - Wind ^, 永久 外 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇It is used to form a fan motor that can output a large torque. However, it does have a large torque ripple and a large iron loss, and a lot of waste is generated when the stator steel sheet is produced. In addition, it is not only a modern trend, but also a future trend exhibition. It can be said that from the Xuxiang Gu magazine, it is found that the output value of the micro (four) products in the field of fine forming is increasing greatly every year. Growth 'Of course, these micro (four) products include the read head of the CD player or magnet machine product, the inkjet head of the printer, the pressure sensor, the micro-horse, etc.; Among them, in terms of growth rate, the small motor has a range of up to 50 times, which is the highest in all micro-system products. Therefore, in view of the above-mentioned conventional fan motor structure, it has a large torque ripple and a large iron loss, and various disadvantages of waste are wasted when manufacturing the stator steel sheet, so how to redesign a claw pole type The structure of the fan motor is improved, and its advantages in addition to conforming to the miniaturization and high efficiency are the subject of the creation. [New content] In view of the above-mentioned problems of the prior art, the present invention is an improved structure of a claw-pole fan motor, which is used to solve the problem of large torque ripple and large iron loss of the motor structure, and also overcomes the production of stator steel sheets. It wastes a lot of waste and thus increases the overall cost. In order to achieve the above object, the present invention is an improved structure of a claw pole fan motor, which comprises a frame body, a certain sub-portion and a rotor portion. The frame body is made of a soft magnetic composite material and has a housing space in the radial direction. The end side extends a plurality of claw poles and is a vertical frame body and a central axis thereof. Further, the stator portion is disposed in the accommodating space and includes a stator winding ring disposed between the claw poles, and the rotor portion is surrounded by the stator portion. In the space, and the package--the fan blade group and a permanent magnet ring are arranged with respect to the stator winding and the claw pole and have a small air gap. The outer periphery of the fan blade group is provided with a magnetic conductive ring and is surrounded by a permanent magnet ring. At the center of the space, the stator windings are energized with the permanent magnets to drive the fan blades to rotate. ^Pole generated magnetic cross-link induction, another purpose of stealing the creation is to provide ~, good, including two frames, a certain sub-section and claw fan motor structure 2 magnetic composite material and axial juxtaposition The frame body has a plurality of claw poles extending from the four sides and is perpendicular to each other, and is disposed in the radial direction, and is parallel to the central axis thereof, and the stator portion is disposed in the accommodating space and includes the stator. The winding ring is disposed between the claws, and the rotor portion is surrounded by the stator portion in the accommodating space, and includes a blade group and a permanent magnet ring which are arranged with respect to the stator winding and the claw pole, and a blade group is provided. The outer ring is provided with a magnetic conductive ring and is surrounded by a permanent magnet ring at the center of the valley between the jade. When the stator winding is energized, the magnetic pole of the permanent magnet is chain-inducted, thereby driving the fan blade group to rotate relative to the stator portion. The creation of the claw-type fan motor of the present invention is improved by the following points, and has the remarkable effect enhancement as described below. The improvement of the fan motor structure is achieved by the use of the soft magnetic composite (10). Due to the loss of the stator winding, the cost can be reduced, which can effectively reduce the iron shape of the stator winding, and reduce the current loss of the stator winding. It can provide a small y -, 轺 torque, and the purpose of reducing the winding coil. The material can also be saved to save the claws of the manufacturing masterpiece. 4 Ma Lai = Ma Qinguanliang 'With the use of soft magnetic composite materials and water electrodes ^ & use · · stator winding - magnetic return flow (4) Flowing through the frame t111, the claw-pole motor of the claw motor is blunt-turned, and then the five-claw pole is read, so that the rotation of the rotor portion is not made as a foreign-frequency hybrid county, and when the claws are extremely sturdy, On, and then inlaid in; κ pole arc-shaped empty door first: the dragon around the coil in the stator shot slot rate, and also depicted in # a, and thus can effectively improve the line 3 * so that the ==: = body Convenience. Understand that, in the relevant embodiments and drawings, there can be advanced - "M308561. [Embodiment] Please refer to the 1 ® 'Looking System' - the structure of the surplus fan motor.
