(71) 的其中一端的中心固設轉軸(75)，此轉軸(75)再穿入 内定子(74)的中心孔(76)，使外轉子(71)得以相對於内定 子(74)旋轉。當通電激磁後，外轉子(71)就圍繞著内定子 (74)旋轉而向外輸出所需的扭矩(Torgue>。由於外轉子 (71)必須圍緩在内定子(74)的外緣旋轉，所以外轉子(71) 的兩端之中，只有其中一端通常是形成筒端面(71a)受到 支撐而已，而另外一端則必須形成開口(71b)，而且是懸 空的。 由於内定子(74)的激磁線圈(72)通電激磁時，它所產 生的電磁場與外轉子(71)的永久磁鐵(7〇)所存在的永久磁 場之間，會產生相吸與排斥的交互作用，使得外轉子(71) 受到此兩種相吸與排斥的交互作用而造成晃動(Vibration) 的現象’並進而因爲此種晃動(Vibration)的現象而誘生振

Description of the invention () [Fields covered by the present invention] The present invention is directed to the "high-efficiency, high-torque, high-support External rotor motor (fourth case) ". [Known technology and its disadvantages] As shown in the eighth figure, the outer rotor type brushless motor is a cylindrical outer rotor (71) provided with a permanent iron (70) and covered with an exciting coil (72). ) And the outer edge of the cylindrical inner stator (74) of the inner stator yoke (73), and a rotating shaft (75) is fixed at the center of one end of the outer rotor (71), and this rotating shaft (75) penetrates into the inner stator ( The center hole (76) of 74) allows the outer rotor (71) to rotate relative to the inner stator (74). When energized, the outer rotor (71) rotates around the inner stator (74) and outputs the required torque (Torgue >). Because the outer rotor (71) must be rotated around the outer edge of the inner stator (74) Therefore, of the two ends of the outer rotor (71), only one end is usually formed to support the cylinder end surface (71a), while the other end must form an opening (71b) and be suspended. Because the inner stator (74) When the exciting coil (72) is energized and excited, the electromagnetic field generated by it and the permanent magnetic field of the permanent magnet (70) of the outer rotor (71) will generate an interaction of attraction and repulsion, so that the outer rotor ( 71) Vibration is caused by the interaction of these two types of attraction and repulsion, and vibration is induced by this vibration. The higher the speed, the greater the centrifugal force. Or, the stronger the magnetic field mentioned above, the more severe the vibration and vibration problems mentioned above will be. Also, because of this kind of problem, it has been impossible to manufacture the rotor type motor from the beginning.

Description of Invention () Rotor motors other than torque. Because of this bottleneck that cannot be broken, outer rotor motors have so far only been used in low-horsepower and low-torque applications, such as motors for cooling fans, record drive motors for record players, and soft The disc drive motor of the disc player, the disc drive motor of the hard disc drive, the motor of the disc player ... etc. The technical bottlenecks encountered by the outer rotor (71) on the support structure have not yet been able to break through. To solve the aforementioned problems, the inventor has previously applied for "high-efficiency, high-torque, high-support external rotor motors (the fourth case)." The fourth complex is for external rotor-type motors due to insufficient support of the external rotor, which makes it impossible to Problems in the field of high efficiency, high horsepower, high torque, and high speed motors Between the open end of the outer rotor portion of the outer rotor motor and the inner stator, due to the interaction of the armature reaction between the outer rotor magnet and the inner stator exciting coil, and the centrifugal force generated during high-speed rotation, etc. The problem of shaking and unevenness caused by the outer rotor provides an extremely superior support bearing for the open end of the outer rotor, so as to provide an extremely superior outer rotor supporting structure for the problem of uneven operation. If the outer rotor motor When the diameter of the outer rotor base is small, the open end of the outer rotor base provided in the fourth case can still be directly connected to the outer circle of the support bearing of the open end. A support bearing with a particularly large diameter must be installed between the open end of the outer rotor base and the inner stator base. 'This large diameter bearing is expensive and increases the unnecessary weight of the motor. In addition, if the outer rotor base The seat is made of sheet metal with a punch, and when the outer rotor base diameter is designed to be larger, in order to increase the output power of the motor, the outer rotor base The thickness must correspond to the magnetism of the inner stator; _ 4 scales are applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) ~~~ ------------------------ ----- (Please read the precautions on the back before filling out this page) 434979 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. The description of the invention is relatively thicker, and once the thickness of the outer rotor base is increased When it is large, it cannot be manufactured by drawing. Therefore, the main body of the outer rotor base, the front cover and the rear cover are separately manufactured, and then they are combined into one. [Objective of the present invention] The purpose of the present invention is to provide a high-efficiency, high-torque, high-support outer rotor for the problem that the open-end support bearing derived from the increase in the diameter of the outer rotor base must also use a large outer diameter. Motor (Eleventh Case). " It is enclosed at the front end or rear end of the outer rotor base, respectively, to cover the front end cover or the rear end cover, so that the front end of the outer rotor base and the front motor rotation shaft, and the back end of the outer rotor base and the rear support bearing. , All form a connection relationship, so that the outer diameter of the outer rotor support bearing can be selected to be smaller. Another object of the present invention is to provide a "high-efficiency, high-torque, = supported rotor motor (tenth-case)" which can be further provided with a vent hole or a cooling blade on the front end cup and the rear end cover, respectively, so that With the rotation of Qin Zi, the heat is dissipated inside the stator of the outer rotor motor. The present invention further addresses the condition of the larger output power motor L. Due to the corresponding amount, the thickness of the outer rotor base is increased, so the manufacturing is "synthesized. The end cover and the rear end cover are separately manufactured, and then they are combined. [Technical content] The high efficiency, high torque, and high (tenth-case) provided by the present invention include: an inner stator, the inner; a stator weaving paste, and should be provided corresponding to the core of the motor; the inner stator The base is close to the inner stator base. ^ I ^ Order ------ ^ (Please read the notes on the back before filling in this page) (210X297 mm) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 — «— ______B7 V. Description of the invention () ~ ~ '~ The center of the stator should be set to read the inner stator base positioning end to provide the above-mentioned inner stator positioning end as a concentric connection. The child is locked to the inner stator base by screws and nuts for tight coupling. The bottom of the positioning end of the inner stator base extends outwardly from the motor shaft center (inner stator center). The outer end of the rotor records the positioning end. Rotor rear bearing end and inner stator base There is at least one wire perforation between steps so that the external control signal of the motor can communicate with the electrical connector of the excitation coil or control circuit of the inner stator through the wire perforation. The outer rotor is enclosed by the inner stator, relative to the inner. The outer rotor includes a base body of the outer rotor, which provides an armature response (for a fixed load of the armature conductive magnet 1U). The armature conductive magnet should react with the armature relative to the inner stator.
