摘要： PROBLEM TO BE SOLVED: To miniaturize a fuel pump for pressurizing fuel by driving a pump part by rotation of an armature. SOLUTION: A motor part 13 of the fuel pump 10 is constituted by rotatably arranging the armature 50 on the inner peripheral side of a permanent magnet 40. A rotor core 52 of the armature 50 is formed by laminating a magnetic steel plate. The rotor core 52 forms a plurality of magnetic pole cores 53 in the rotational direction, and a coil 60 is wound on the respective magnetic pole cores 53. A magnetic steel plate 56 having the plate thickness thicker than the magnetic steel plate 54 except for axial both ends, is laminated on axial both ends of the rotor core 52. The magnetic steel plate 56 has a collar part 56 formed by bending the outer peripheral side toward the commutator 70 side and the pump case 22 side by press working with every magnetic pole core 53. The coil 60 is wound between an outer peripheral side surface 77 and the collar part 57 of a commutator 70. A bearing part 23 of a pump case 22 supporting a bearing 24, overlaps in the radial direction with a recessed part 100 of the armature 50, and enters the inside of the armature 50 in the axial direction.

摘要： PROBLEM TO BE SOLVED: To provide a direct-current motor which allows increase in space factor of an armature coil 7 and easy change in connection between the armature coils 7. SOLUTION: An armature core 6 is provided in such a manner as to be split into an inside core 6A and an outside core, which are combined together by press-in an fitting after a bobbin 9, around which the armature coil 7 is wound, is assembled to the inside core 6A. The armature coil 7 is wound around the bobbin 9, and both coil ends are connected to male terminals 10 provided in the bobbin 9. A commutator is provided with a female terminal into which the male terminal 10 of the bobbin 9 is fitted, and each of the female terminals undergoes internal connection so as to be brought into conduction with a prescribed segment. Such a constitution enables the connection between the armature coils 7 by only making the male terminal 10 fitted into the female terminal. Consequently, provision of the commutators different in the internal connection allows easy change of the connection between the armature coils 7 only by replacing the commutator.

摘要： PROBLEM TO BE SOLVED: To extend the service life of a motor by reducing rectified voltage for restraining arc discharge generation, or, to reduce electromagnetic noise. SOLUTION: Six coils 7 are connected to each segment 8a in which one end thereof constitutes a rectifier 8, and the other end of each coil is connected to neutral positions n1 and n2. In two pairs of brushes 4, a plus-side brush 4 of one pair is short-circuited with a minus-side brush 4 of the other pair. This makes it possible for a primary coil group and a secondary coil group to be energized in series with each other through the two pairs of brushes 4. With this constitution, the voltage at one phase of coils 7 is decreased by a half of that in a conventional type, which also reduces the voltage when rectified in a half. This would mean that even if the power voltage doubles, the voltage when rectified would not increase more than that in a conventional type. As a result, arc discharge generated between the brushes 4 and the rectifiers 8 when rectified can be restrained, so that wear to the brushes 4 and the rectifiers 8 can be reduced. It is thus possible to extend the service life of the motor.

摘要： PROBLEM TO BE SOLVED: To realize cost reduction for a drive circuit of a brushless motor. SOLUTION: Ten armature coils A1, A2,..., El, E2 in total of a brushless motor 14 are equally divided into two power feeding groups G1, G2 and five armature coils are star-connected, respectively. Two drive circuits 40 are provided corresponding to two power feeding groups G1, G2 and power feeding to the armature coils is switched with discrete drive circuits 40 for every power feeding groups G1, G2. For example, when a motor of specification 4A is driven with the drive circuit 40 of specification 2A, it is enough to use two drive circuits 40 of the specification 2A and when the motor of specification 6A is driven, it is enough to use three drive circuits 40 of specification 2A. Moreover, when the motor of specification 2A is driven, it is enough to use only one drive circuit 40 of specification 2A.

摘要： PROBLEM TO BE SOLVED: To provide a piezoelectric sensor unit capable of reducing costs by forming a piezoelectric sensor and a level sensor out of one part, or one piezoelectric element, thereby reducing the number of parts and man-hours for assembly. SOLUTION: The piezoelectric element 21 is mounted on the ceiling wall of a fuel tank for vehicle. When the piezoelectric element 21 receives stress corresponding to the inner pressure of the fuel tank, the piezoelectric element 21 generates voltage corresponding to the stress, and the voltage generated at the piezoelectric element 21 is measured to measure the inner pressure of the fuel tank, thereby using it as a piezoelectric sensor. By applying AC voltage to the piezoelectric element 21, an ultrasonic wave is generated from the piezoelectric element 21, the wave level of the fluid fuel in the fuel tank can be measured by clocking the time until the ultrasonic wave is reflected on the fluid level of the fluid fuel in the fuel tank and returned to the piezoelectric element 21, thereby using it as a level sensor.

摘要： PROBLEM TO BE SOLVED: To provide a fuel pump where dislocation of a rotor core with respect to a rotary shaft to an axial direction during filling a resin material can be prevented, and to provide a manufacturing method of the pump. SOLUTION: An armature 50 is freely rotatably arranged on an inner peripheral side of a permanent magnet 40. A shaft 42 is press-fitted to the rotor core 52. The resin material 70 is insulating resin, and the armature 50 and a commutator 60 are filled with it so that it covers a fusing part of a commutator terminal and winding of a coil except for a contact face with a brush. In a boundary between an end on a commutator 60-side of the rotor core 52 and the resin material 70, the resin material 70 is dented to the inner peripheral side compared to the rotor core 52, and an outer diameter of the resin material 70 on the commutator 60-side of the rotor core 52 is smaller than that of the rotor core 52 in a state where the armature and the commutator are filled with the resin material 70. Thus, a step 80 is formed on a whole periphery of the boundary between an end 56 of the commutator 60-side of the rotor core 52 and the resin material 70 with such a structure.
