摘要： Fan includes wires electrically connected to the circuit board outwardly extends from a base toward a housing along a rib connecting the base supporting a motor and the housing. The housing includes a wire-receiving section defined by a through hole extending in the housing, and a slit connecting the through hole and an outside of the housing along a direction in which the through hole extends. The wires are inserted into the wire-receiving section via the slit, and then, led outside of the housing through the wire-receiving section. A wire-holding member is then inserted into the wire-receiving section to close the slit to prevent the wires from coming out of the wire-receiving section and to restrict the movement of the wires.

摘要： A motor includes a heat dissipating structure. The motor may be used for a fan and includes on an upper surface of a circuit board a heat dissipating layer. The heat dissipating layer has a high thermal conductivity. The fan also includes a coil provided on the teeth of a stator core. The heat dissipating layer and the coil axially face each other, and thermal conductive members are arranged therebetween. An outer dimension of the circuit board is greater than that of an impeller cup so that a radially outward portion of the circuit board protrudes radially outwardly from the impeller cup. The heat generated by the coil is transferred to the heat dissipating layer via the thermal conductive members. Therefore, the heat is dissipated from a wide area, which efficiently dissipates heat from the fan. In addition, since the circuit board and the heat dissipating layer protrude radially into an air-flow generated by an impeller, the heat transferred to the heat dissipating layer is actively dissipated.
摘要翻译： 电动机包括散热结构。 马达可以用于风扇，并且在电路板的上表面上包括散热层。 散热层具有高导热性。 风扇还包括设置在定子芯的齿上的线圈。 散热层和线圈彼此轴向相对，并且导热构件被布置在它们之间。 电路板的外部尺寸大于叶轮杯的外部尺寸，使得电路板的径向向外部分从叶轮杯径向向外突出。 由线圈产生的热量经由导热部件传递到散热层。 因此，热量从广泛的区域消散，从而有效地散发风扇的热量。 此外，由于电路板和散热层径向突出到由叶轮产生的空气流中，所以传递到散热层的热量被积极地消散。

摘要： An axial flow fan unit includes an intake side axial flow fan, an exhaust side axial flow fan, and at least one intermediate axial flow fan. Each of the axial flow fans includes an impeller having blades rotatable about a central rotation axis, a motor arranged to rotate the intake side impeller, and a housing having an inner circumferential surface that surrounds the impeller. The rotational direction of the impeller in the intermediate axial flow fan is different from that of the impellers adjacent thereto.

摘要： A motor arranged to rotate an impeller includes a rotor magnet fixed to a shaft, and a stator arranged opposite to the rotor magnet. The motor is arranged on an axially lower side of an impeller cup. The stator is fixed to an inner circumferential surface of a stator support portion. An opening-side end portion of the impeller cup is arranged opposite to an upper surface of the stator support portion. The upper surface of the stator support portion includes an expanded portion defined in a portion thereof which is opposed to the opening-side end portion of the impeller cup. The expanded portion is preferably located a greater distance from the opening-side end portion of the impeller cup than a distance between the opening-side end portion and a remaining portion of the upper surface of the stator support portion.
