The motor section (2) of the fuel pump has a columnar rotor (21) having a shaft (7) for rotating the pump section (1), and a ring magnet (5, 35, 45, 55, 65, 75, 85) surrounding an outer circumference face of the rotor (21). There is provided a minute clearance between the rotor (21) and the magnet (5, 35, 45, 55, 65, 75, 85). The motor section (2) further has a cylindrical yoke (4, 34, 46, 56, 66) surrounding and contacting an outer circumference face of the magnet (5, 35, 45, 55, 65, 75, 85). A fuel passage (27, 37, 47, 57,67, 77, 87, 97, 127) having a sufficient cross sectional area is formed at a location removed from a magnetic path along which a substantial portion of magnetic flux (F) flows between the rotor (21), the magnet (5, 35, 45, 55, 65, 75, 85), and the yoke (4, 34, 46, 56, 66).

摘要： An anisotropic bonded magnet molded in a ring shape to be used to excite a brush-equipped direct current motor. A magnetic flux density distribution in each of magnetic pole sections of the ring shape forms an asymmetric distribution which includes a magnetic flux density reduced portion wherein the absolute value rises from a neutral axis opposite to a rotation direction of an armature with a delay with respect to a rotation direction of the armature, and in which the absolute value falls more rapidly than a rise thereof in the rotation direction of the armature with respect to a neutral axis in the rotation direction of the armature.

摘要： The rectifying characteristic of a brush-equipped direct current machine is improved, and the life of the machine is extended.As illustrated in FIG. 2, a magnetic flux density reduced portion in which the magnetic flux density is reduced is formed in a magnetic pole section of an anisotropic bonded magnet. The position in the magnetic pole section formed with the magnetic flux density reduced portion is formed at the position at which, when a rectifier coil moves in a rectification section, the absolute value of the density of a magnetic flux penetrating the rectifier coil is increased due to the influence of the magnetic flux density reduced portion. Thus, an inverse voltage can be induced in the rectifier coil in the direction of inversion current during a rectification period. It is therefore possible to facilitate the inversion of the current, and to compensate for inadequate rectification and improve the rectifying characteristic. Accordingly, the occurrence of sparks at the end of the rectification can be prevented.
摘要翻译：刷机直流电机的整流特性得到改善，延长了机器的使用寿命。如图1所示。如图2所示，在各向异性粘结磁体的磁极部分中形成磁通密度减小的磁通密度减小部分。形成有磁通密度减小部分的磁极部分中的位置形成在整流器线圈在整流部分中移动的位置处，穿过整流器线圈的磁通密度的绝对值增加，对磁通密度减小部分的影响。因此，在整流期间，逆变电流的方向可以在整流器线圈中产生反向电压。因此可以促进电流的反转，补偿不充分的整流，提高整流特性。因此，可以防止整流结束时发生火花。

摘要： The challenge to be solved by the present invention is the miniaturization of a 1-300 W class of motor. This can be achieved by using a hollow-cylinder shaped anisotropic bonded magnet magnetized in a 4-pole configuration. The anisotropic bonded magnet has a maximum energy product approximately 4 times greater than the conventional sintered ferrite magnets. The use of a 4-pole configuration shortens the magnetic path length of the individual magnetic circuits and the magnetic force contributing to the torque is increased. When the torque is kept the same as in the conventional motor, the length of the electromagnetic rotor core and the axial magnet length can be reduced. In this fashion, 1-300 W class motors can be reduced in size.
摘要翻译：本发明要解决的挑战是1-300W级的电动机的小型化。这可以通过使用以4极结构磁化的中空圆柱形各向异性粘结磁体来实现。各向异性粘结磁体具有比常规烧结铁氧体磁体大约4倍的最大能量积。使用4极配置缩短各个磁路的磁路长度，并且增加对扭矩的磁力。当转矩保持与常规电动机相同时，可以减小电磁转子铁芯的长度和轴向磁体长度。以这种方式，1-300W级电机的尺寸可以减小。
