摘要： In a three-phase, four-pole, four-parallel-circuit stator winding of an electrical rotating machine, each of two sets of U-phase output terminals U1, U2 is formed of two sets of parallel circuits each formed of windings having a same pitch (one is formed of first and second winding circuits 1, 2 and the other is formed of third and fourth winding circuits 3, 4). The winding of each winding circuit is formed of two serially-connected coil phase bands (coil phase bands a and b form the first winding circuit 1 and coil phase bands c and d, coil phase bands e and f, and coil phase bands g and h form the second, third, and fourth winding circuits 2, 3, 4, respectively). A voltage vector phase difference and a voltage difference between the winding circuits can be eliminated without providing a jumper wire to winding end portions.

摘要： An axial flow fan is provided having an airfoil shape that improves efficiency of the axial flow fan and increases the structural strength and workability/formability of the thin trailing edge portion. The axial flow fan includes a blade having a suction surface, a pressure surface, and a trailing edge surface; the suction surface has the same in shape as a predetermined airfoil including an NACA-series airfoil; a trailing edge portion on the pressure surface is different in shape from the predetermined airfoil. A feature is that the blade trailing edge portion including the trailing edge portions on the oppositely facing pressure and suction surfaces and the trailing edge, has a thickness greater than that of a trailing edge portion of the predetermined airfoil and strength equaling or exceeding a predetermined strength.

摘要： A fixing structure of a radial lead of a rotating electrical machine connects slip rings provided to a rotation shaft of a rotor and axial leads disposed in a center hole of the rotation shaft and supplying a current to a rotor coil. A radial lead is inserted into a radial lead hole penetrating through the rotation shaft in a radial direction from the center hole and a tapered male screw formed at one end is threaded into a tapered female screw formed in the axial lead while the other end is electrically connected to the slip ring. A sealing member installed to a step portion of the radial lead hole is fastened, via a spacer, by a fastening nut threaded into a straight screw of the radial lead, so that a side of the center hole is maintained airtight from an outside.
