摘要： A power output apparatus 20 implements a smooth switching between the connection of a rotor-rotating shaft 38 of an assist motor 40 with a crankshaft 56 of an engine 50 and the connection of the rotor-rotating shaft 38 of the assist motor 40 with a drive shaft 22, and enables the power output from the engine 50 to be output to the drive shaft 22 with a high efficiency. The power output from the engine 50 is converted to a desired power by a clutch motor 30 having rotors 31 and 33 respectively linked with the crankshaft 56 and the drive shaft 22 and by the assist motor 40 connected to either the crankshaft 56 or the drive shaft 22 via a first clutch 45 and a second clutch 46, and is output to the drive shaft 22. The connection of the assist motor 40 is switched in the state where both the clutches 45 and 46 are set in ON position, when the revolving speed of the engine 50 is made coincident with the revolving speed of the drive shaft 22. This effectively reduces a variation in torque output to the drive shaft 22 in the course of the switching operation and enables the power to be output to the drive shaft 22 even in the course of the switching operation.

摘要： A power output apparatus (20) of the present invention includes a clutch motor (30), an assist motor (40), and a controller (80) for controlling the clutch motor (30) and the assist motor (40). The clutch motor (30) includes an outer rotor (32) linked with a crankshaft (56) of a gasoline engine (50) and an inner rotor (34) connecting with a drive shaft (22). The assist motor (40) includes a rotor (42) connecting with the drive shaft (22). A control CPU (90) of the controller (80) controls a first driving circuit (91) to enable the clutch motor (30) to carry out the regenerative operation. The clutch motor (30) accordingly regenerates energy corresponding to a slip between the outer rotor (32) and the inner rotor (34) as electric power. The control CPU (90) then controls a second driving circuit (92) to enable the assist motor (40) to carry out the power operation with the electric power regenerated by the clutch motor (30), thereby rotating the drive shaft (22) in the reverse of the rotation of the crankshaft (56). The power output apparatus (20) of the invention thus constructed can transmit or utilize the power generated by the gasoline engine (50) at a high efficiency and enable the drive shaft (22) to rotate in the reverse of the rotation of the crankshaft (56).

摘要： A rotor piece has a plurality of holes 12. Each hole holds therein a plurality of substantially divided permanent magnets 14 that are arranged in a circumferential direction. Therefore, each permanent magnet is small and the flow passage of eddy currents becomes narrow, so that the magnitude of eddy currents becomes small. The total eddy currents in all the permanent magnets is also reduced, so that the eddy current loss can be reduced and the heat generation of the motor can be reduced. Adjacent ones of the substantially divided permanent magnets may be interconnected at portions thereof. One or more of the substantially divided permanent magnets 14 in one or more holes may be ferrite magnets, with other permanent magnets being rare-earth magnets.

摘要： In a method for manufacturing a stator of a motor, when an angular line is used to increase the occupancy rate of line members for coil pieces inserted into slots, not-slot-inserted parts project from a stator core. This results in enlarging the size of a stator, and damaging coatings via interference between a coil piece and other parts. In order to solve these problems, an angular line is first wound a predetermined times. Then, slot-inserted parts (a coil side) are separately clamped, and one of them is rotated by 180 degrees in a direction perpendicular to the winding direction, so that twisted parts are formed on coil ends. The coil sides are sequentially inserted into predetermined slots while maintaining respective twisted parts substantially parallel to each other, until a stator is completed.

摘要： A stator core for a motor in which a member with rounded edges is used to prevent the electrical breakdown of the winding of a coil which may occur at a slot edge therein. End plates 18 are disposed on ends of the stator core 10 formed of laminated magnetic steel plates 12. Each of the end plates 18 has substantially the same pattern as each magnetic steel plate 1, viewed from the axis of the motor. The elongate surface 18a of the end plate 18 continues smoothly from the inner surface 16a of each of slots 16 to the rounded edge surface 18b. The rounded edge surface extends smoothly from the elongate surface 18a to the end surface 18c of the end plate 18. This structure can eliminate sharp edges from the fringe of the slot 16, thus preventing the electrical breakdown of a coated conductor 22 in the coil which may occur at the edges.

摘要： The present invention provides a system for detecting a rotational orientation or electrical angle of a rotor without any specific sensor so as to efficiently control a synchronous motor even while the rotor is at a stop or rotates at a relatively low speed. An electrical angle of a rotor (50) is determined according to a previously stored relationship between inductances of different interphases and electrical angles. At a first step, an electrical angle .phi. is calculated either in a range of 0 through .pi. or in a range of .pi. through 2.pi. by approximation. At a second step, a range where the electrical angle .phi. belongs to is specified by taking advantage of asymmetrical property of a maximum current in response to a voltage applied to each interphase. An equivocal electrical angle .theta. is then determined in a range of 0 through 2.pi.. In order to control the driving current of a three-phase synchronous motor (40) at better efficiency, a preferable system of the invention determines the electrical angle according to the above method while the rotor (50) is under inactivating condition or rotates at a speed of less than a predetermined rotating speed, and detects the electrical angle with a reverse electromotive voltage while the rotor (50) rotates at a speed of not less than the predetermined rotating speed.

摘要： Molded coil pieces inserted into a slot are separately connected to molded coil pieces belonging to another slot of the same phase as the former coil pieces by a connecting member. The connecting member has conductive members laminated in a direction perpendicular to a rotating shaft of the rotor in the motor via insulating layers, and the molded coil pieces are separately connected to each other by these conductive members, whereby the protrusion of a coil end from each slot can be reduced, which permits the miniaturization and the weight reduction of the motor. Furthermore, the dimensional accuracy of the connecting members can be improved by a simple constitution and manufacturing process, whereby the characteristics of the electric motor can be remarkably improved.

摘要： A circular wire with a circular cross section is wound on a coil reel. When a winding-form motor rotates a winding form, the circular wire is pulled and drawn from the coil reel. Rectangular forming rollers press the circular wire, so that a rectangular wire with a rectangular cross section is formed. The rectangular wire is directly wound on the winding form to be formed into a rectangular-wire coil. Because forming rectangular wire and winding on the winding form are carried out in a sequence of contiguous processes, a separate process for removing torsion set of the rectangular wire is unnecessary. The rectangular-wire coil can be formed from inexpensive circular material wire by a simple and low-cost apparatus. It is also possible and preferable to make dimensions and a shape of the rectangular wire variable by controlling clearance widths between the forming rollers and tension acting on the rectangular wire that has passed through the rollers.

摘要： Directional electromagnetic steel plates are laminated, and a plurality of stator and rotor core segments are produced by generating into an approximate U-shape so as to provide a U-shaped cross section of the lamination. The direction of high magnetic permeability of the directional electromagnetic steel plates is aligned during lamination with the direction along said U-shape. The side portions of the U-shape adjoin each other and are arranged along the circumference to produce the stator and rotor cores. As the electromagnetic steel plates are laminated, fluctuation in the components in the circumferential direction of the magnetic flux within the magnetic poles and salient poles can be reduced, and iron loss can thus be lowered. In addition, the direction of high magnetic permeability of the directional electromagnetic steel plates coincides with the direction of the magnetic flux creating a much stronger magnetic flux.
摘要翻译：定向电磁钢板被层叠，并且通过产生大致U形来制造多个定子和转子铁芯段，以便提供层压体的U形横截面。方向性电磁钢板的高磁导率方向在沿着所述U形的方向的层叠期间对准。 U形的侧部彼此相邻并且沿着圆周布置以产生定子和转子芯。随着电磁钢板的层叠，能够降低磁极和凸极内的磁通的圆周方向的成分的波动，能够降低铁损。此外，定向电磁钢板的高磁导率方向与磁通方向一致，产生更强的磁通量。
