    摘要: There is provided an electric rotary machine having, in particular, a large capacity, in which a volume of cooling air is ensured for the axially center part thereof so as to make the temperature distribution uniform in the axial direction of the rotor and the stator. Each of gas coolers in the electric rotary machine is divided into not less than two of passage parts in which streams run in two directions in opposite to each other are created, and a stator-cooling connection passage is formed so as to connect not less than two passage parts located in the radially outward part of the stator 2 and axially defined by partition walls with the passage parts in the gas coolers in the electric rotary machine. With this arrangement, cold gas can be led into the axially center part of the stator without increasing the total ventilation resistance, and accordingly, it is possible to prevent occurrence of temperature rise in the axially center parts of the stator and the rotor, which would be caused in the electric rotary machine having, in particular, a large capacity.

    摘要: Efficient ventilation and cooling for a rotor is realized at a low cost by reducing the pressure loss at inlet flow passages, which lead to axial flow passages through which cooling gas flows to the rotor. Inlet flow passages leading to axial flow passages for cooling an interior of the rotor are composed of convex portions, which are formed axially on surfaces of a rotor spindle between and below coil ends of the rotor, and concave grooves formed between the convex portions. Also, the convex portions are designed to have a height increasing toward a downstream side, and assuming that L designates an length of the convex portions, L is greater than a radial difference between the positions of a maximum radius and a minimum radius of the convex portions.

    摘要: An apparatus in which a magnetic field is generated by an excitation coil provided in the outside of a conduit and electromotive force generated in electrodes attached on the conduit is detected to thereby measure a flow rate of a fluid flowing in the conduit, in which the conduit is made thinner in a manner so that a ratio of the axial length of the conduit to the inside diameter of the conduit is set to a value within a range of from 0.2 to 1.0, and in which correction data previously analyzed in accordance with magnetic permeability and inside surface conductivity of a mate piping to which the conduit is to be connected are stored so that a detection signal from the electrodes is corrected on the basis of the correction data to thereby measure the flow rate of the fluid flowing in the conduit.
