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 measure a gap between a rotary body and a casing precisely by forming a T-shaped probe to be slidably contacted with the inner periphery of a member on the casing side and a converter for converting the mechanical displacement of the T-shaped probe into an electrical signal. CONSTITUTION:The T-shaped probe 11 projected from an electronic micrometer 10 is slidably contacted with the inner peripheral edge of a seal fin 5. At that time, zero point adjustment of the micrometer 10 is executed. When the shaft 23 of a turbine is rotated, a pulse signal corresponding to the turning angle is outputted from a pulse oscillator 22 to a pulse counter 20. Every counting of the previously fixed number of pulses, the counter 20 outputs a measuring timing pulse to a signal processor 7. The processor 7 receives a moving distance of the probe 11 from the outer periphery of a shroud 6 through the micrometer 10. The device 7 A/D converts the inputted signal and outputs the digital signal to a recorder 21.
