摘要： A commutator includes six segments disposed in the direction of rotation, and is attached to one axial end of an armature. By the commutator rotating together with the armature, each of the segments successively contacts a brush. Each of the segments is electrically connected with terminals through mid-terminals. Three of the six terminals, non-adjacent and alternatingly located in the direction of rotation, are electrically connected directly with mid-terminals facing in radial opposition. Capacitors are electrically connected directly with the terminals adjacent in the direction of rotation. Discharge does not occur between the brush and segments when the brush separates from the segments accompanying rotation of the armature, since electromagnetic energy built up in the coils of the armature is temporarily built up in the capacitors.

摘要： PROBLEM TO BE SOLVED: To provide a stacked cores for a rotating machine which can reduce the eddy current loss. SOLUTION: On a sheet core 2, recessed parts 4a formed on the surface of a magnet pole part and protruding parts 4b that project on its back surface are provided. The recessed parts 4a and the protruding parts 4b of the sheet cores 2, which are stacked, are press-connected to each other. But press- connectable positions and non press-connectable ones of the recessed parts 4a to the protruding parts 4b are provided alternately in the circumferential direction. In the stacked cores made by stacking these sheet cores 2, the press- connecting parts 'A' are dislocated in the circumferential direction for each group of a given number of pieces of the sheet cores 2. This structure prevents the press-connecting parts A from continuing in the stacking direction, so that the eddy current loss can be reduced sharply. Also, by rotating and stacking a given number of pieces of the sheet cores 2 in the circumferential direction, the total length of the stacking direction can be made equal over the entire circumference. In this way, good balance is made, when it is rotated, with the effect of lessening the vibrations and abnormal noises.

摘要： PROBLEM TO BE SOLVED: To prevent decrease of revolutions at the time of the drop in motor driving voltage and to improve output characteristic at the time of the drop in motor driving voltage, by changing the changeover timing of conduction to the armature coil of each phase in accordance with a detected motor drive voltage. SOLUTION: A drive control circuit 31 detects an induced voltage generated in the armature coil of a non-conducting phase as a neutral point voltage, based on which the circuit 31 also detects the rotational position of a magnet rotor 23. Then, in accordance with the rotational position of the magnet rotor 23, groups of MOSFETs in the upper and lower sections of each phase are switched on in sequence and the armature coils of three phases out of five phases are turned on simultaneously to drive a brushless motor 14. The voltage of a battery (a motor driving voltage) is monitored based on the output signal of a voltage detecting circuit while the motor is driven. When the battery voltage is higher than a discriminating one, the changeover timing of the conducting phases is fixed to a constant timing that brings about the highest motor efficiency. When it is lower than the discriminating voltage, the changeover timing of the conducting phase is advanced.

摘要： PROBLEM TO BE SOLVED: To provide a fuel pump allowing boosted fuel to smoothly flow to the magnet side of a motor part.
SOLUTION: A pump case 22 constitutes a case member for holding an impeller rotatably. When the impeller of the pump part is rotationally driven by the motor part, fuel boosted in a pump passage 202 is discharged to the permanent magnet 40 side of the motor part from a discharge port 204. Two permanent magnets 40 are installed in a circumferential direction, and clearances 208 are formed between the permanent magnets 40, 40. An imaginary straight line 220 extending in a fuel discharge direction along an inner side face 205 on the rotating direction front side of the discharge port 204 passes between the discharge port 204 side ends of the adjacent permanent magnets 40. The imaginary straight line 220 inclines onto the permanent magnet 40 side toward the rotating direction front side with respect to the end face 23 on the permanent magnet 40 side of the pump case 22. An angle α formed by the imaginary straight line 220 and the end face 23 of the pump case 22 is set in 10°≤α≤60°.
