Abstract: A permanent magnet synchronous machine includes a rotor including a core body and an overhang protruding further in an axial direction than a core of a stator. An end surface of the core body includes an N-region disposed on a north pole and an S-region disposed on a south pole. The overhang includes first permanent magnets arranged along an outer edge of the end surface with distances therebetween and a plurality of second permanent magnets disposed on the end surface and adjacent to the first permanent magnets. The first permanent magnets include at least one of a permanent magnet comprising a north pole facing the N-region and a permanent magnet comprising a south pole facing the S-region. The second permanent magnets are provided in the configuration which causes the second permanent magnets to generate a magnetic flux extending from the S-region toward the N-region.

Abstract: A thermal electric power generator includes an evaporator, an expander, an electric generator, a condenser, and a pump. A working fluid used in the thermal electric power generator is an organic working fluid. The evaporator includes a heat exchanger, a bypass channel, and a flow rate adjustment mechanism. The bypass channel allows a heat medium to bypass the heat exchanger. The flow rate adjustment mechanism adjusts a flow rate of the heat medium to be supplied to the heat exchanger and a flow rate of the heat medium to be supplied to the bypass channel.

Abstract: A Rankine cycle device in the present disclosure includes an evaporator as a heater, an expander, a cooler, a first temperature sensor, a second temperature sensor, and a control device. The first temperature sensor detects a temperature of the working fluid flowing from an outlet of the heater to an inlet of the expander in the circuit of the working fluid. The second temperature sensor detects a temperature of the working fluid flowing from an outlet of the expander to an inlet of the cooler. The controller controls a number of rotation of the expander based on a difference between a detected temperature of the first temperature sensor and a detected temperature of the second temperature sensor.

Abstract: A combined heat and power system according the present disclosure includes a Rankine cycle apparatus including an evaporator that heats a working fluid by heat exchange between the working fluid and a heat source medium, an expansion machine that converts expansion power of the working fluid into rotational power, and a condenser that cools the working fluid by heat exchange between the working fluid and a heat medium, and a thermal circuit for using the heat medium heated by the condenser. An expansion volume ratio of the expansion machine is equal to or less than an expansion ratio in a theoretical Rankine cycle determined based on a state of a temperature and a pressure of the working fluid at a discharge port of the expansion machine and a state of a temperature and a pressure of the working fluid at a suction port of the expansion machine.

Abstract: A gas turbine system (1A) includes a gas turbine unit (2) and a cooling fluid generator (5). The gas turbine unit (2) includes a first compressor (21) and a first expansion turbine (23) coupled to each other by a first shaft (22), a combustor (26), and a fuel tank (30). A fuel held in the fuel tank (30) circulates through a fuel circulation passage (31). A working fluid that has a pressure increased by the first compressor (1) is extracted from the gas turbine unit (2). The cooling fluid generator (5) includes a cooler (55) for cooling, with the fuel flowing through the fuel circulation passage (31), the working fluid that has been extracted from the gas turbine unit (2), and a second expansion turbine (53) for expanding the working fluid that has flowed out of the cooler (55).
