摘要： PROBLEM TO BE SOLVED: To increase energy density, by specifying the number of the poles of a permanent magnet, and specifying the number of slots which permits a three-phase armature winding formed at a stator iron core to be disposed for concentrated winding. SOLUTION: Number of the poles of a permanent magnet 2 in a rotor iron core 3 is formed of 14 pieces and the number of slots is formed of 12 pieces, which permits three-phase armature windings U, V, W, U', V', W' formed at a stator iron core 1 to be disposed for concentrated winding. Therefore, the energy density Edc is improved by forming multi-polarization of the 14 poles, thus enabling to attain size reduction of 10 to 15% in a motor volume compared to conventional embodiments. Quantity of magnet used can also be reduced by 30 to 40% from a product with identical demagnetization strength compared to the conventional embodiment, thus enabling to attain cost reduction. The current capacity of a deriving amplifier is not changed by forming multi- polarization, therefore, it is possible to use a power semiconductor element equivalent to that of a conventional motor. It is also possible to attain the equivalent performance to that of the conventional motor in cogging torque.

摘要： PURPOSE:To improve torque response even in transient are as, while maintaining high efficiency operation of motor in steady area, by performing control while separating the armature voltage into voltage drop due to armature current and a voltage induced through rotation of motor and field current. CONSTITUTION:A current command generator 4 generates a field current com mand If* and an armature current command Ia* based on a torque command taue* and a field current If detected, respectively, through a torque command unit 3 and a field current sensor 8. An armature controller 5 performs PID control based on the difference between the command Ia* and an actual arma ture current Ia detected through an armature current sensor 6 and produces an armature control voltage by adding a voltage command, induced only through the armature current Ia, to a voltage induced through the field current If and an actual rotary speed of motor detected through a motor rotation sensor 11. A field controller 7 performs PID control based on the difference between the command If* and the current If thus producing a field control voltage.

摘要： PURPOSE:To enable operating a motor at the highest efficiency by providing a command generator means for generating field current pattern at the highest efficiency corresponding to a torque command value as a field current command and for generating an armature current command by using a torque command value and an actual field current value. CONSTITUTION:A field current pattern value at the highest efficiency corresponding to a torque command value te* from a torque command apparatus 3 is generated from a pattern generator 4 as a field current command value to a field controller 7. On the other hand, an armature current command value to an armature controller 5 is generated from the pattern generator 4 by using an actual field current value obtained by a torque command value te* and a field current sensor 8. Because an armature current also converges on the highest pattern by such control, it is possible to realize the highest efficiency operation of a motor.

摘要： PROBLEM TO BE SOLVED: To prevent measurement error due to outer wind by fixing an open skirt hood to the top of a Venturi stack so that the lower fringe part of the hood is below the upper fringe part of a duct. SOLUTION: The Venturi stack 15 comprises a Venturi tube 2 produced by constricting the intermediate part of a tubular duct 1 and measures the flow rate of passing air based on the pressure in a static pressure hole 10 prior to constriction and the pressure in a static pressure hole 11 at a constricted part. An open skirt hood 20 is fixed to the top of the duct 1. The hood 20 has inside diameter larger than the outer diameter at the top of the duct 1 and fixed such that the lower fringe part of the hood 20 is covered with the upper fringe pat of the duct 1 by means of a supporting rod 21. The air flows into the duct 1 through the gap between the hood 20 and the duct 1. A turbulence accelerator comprising a flange-like plate 25 is fixed along the upper surface of the supporting rod 21 in order to vary the incoming air flow thus ensuring a stabilized measurement.

摘要： PURPOSE:To control advancing direction easily by individually driving right and left sprockets, through separately excited DC machines, with a DC power obtained by converting the output of an AC generator which is driven through an engine and feeding excessive power, produced from the DC machine, to a regenerative resistor. CONSTITUTION:Output from an AC generator 2, driven through a prime mover 1 such as an engine or a turbine, is subjected to power conversion 3 to produce DC power. DC power is then fed, individually, to field current controllers 12, 13 for two separately excited DC motors 8, 9 which convert the DC power into driving force for right and left sprockets in order to control the current to be fed to the field coils 6, 7 of a separately excited DC motor 89 independently thus controlling the speed of the DC motor individually. When the system enters into a brake mode, a circuit breaker 14 is opened while circuit breakers 15, 16 are thrown in simultaneously or individually in order to feed the excessive power, generated in the armature coils 4, 5 in the DC machine, to regenerative resistors 10, 11 thus converting the excessive power into heat.
