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 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 turbocompressor apparatus includes a turbocompressor including a compressor motor, a lubrication pump including a pump motor, a converter that performs electric power conversion between a voltage of a power source and a direct-current voltage of a direct-current voltage unit in a case where electric power is being supplied from the power source to the turbocompressor apparatus; a first inverter that performs electric power conversion between the direct-current voltage and a first alternating-current voltage vector of the compressor motor; and a second inverter that performs electric power conversion between the direct-current voltage and a second alternating-current voltage vector of the pump motor. The compressor motor generates regenerative electric power by regenerative driving and the pump motor is driven by the regenerative electric power in a case where supply of electric power from the power source to the converter is being cut off.

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.
