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： 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： 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： 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： 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： Hard magnetic poles made of a permanent magnet and soft magnetic poles are alternately disposed on the periphery of a cylindrical rotor of a permanent magnet type synchronous motor. The arcuate length of the hard magnetic poles is equal to that of the intervals between the hard magnetic poles, thereby enabling an increase in the ratio of reluctance torque. Therefore, the number of permanent magnets used can be reduced, making production economical, and a back electromotive force can also be lowered. Further, one magnetic pole consists of six slots, and the arcuate length of hard and soft magnetic poles corresponds to a 3-slot pitch, thereby enabling a reduction in cogging torque.

摘要： A motor coil structure has a lamination of in-slot coils incorporated into slots in a stator core and inter-slot connecting wires individually connecting to the end faces of the in-slot coils. Each of the inter-slot connecting wires is in the form of a bar such that the in-slot coils received in two different slots spaced away from each other by slots equal in number to n-1 (where n is the number of phases). Since the space factor depends on the lamination of in-slot coils in the slot, any clearance in the slot can be eliminated to improve the space factor compared with a motor coil structure in which a coil is formed by binding and winding a plurality of wires.
