摘要： A rotating electrical machine such that a power supply unit can be efficiently cooled, with no increase in size in an axial direction of the rotating electrical machine, is provided. A rotating electrical machine main body and a power supply unit are integrally fixed, and a refrigerant passage is provided on the rotating electrical machine main body side of a metal frame configuring the power supply unit. The refrigerant passage and a control part that controls power supplied to the rotating electrical machine main body are disposed in the same plane in an axial direction of the rotating electrical machine main body, and the refrigerant passage is disposed farther to a radial direction outer side of the rotating electrical machine main body than the control part.

摘要： A control device that can prevent the deterioration of temperature estimation accuracy in a rotating electric machine due to its aging deterioration is provided. The control device (10) includes a correction unit (13) to correct at least one of thermal resistance, heat generation, and thermal capacity, which are physical quantities to build a thermal circuit model (30-1) covering a thermal circuit of a rotating electric machine (1), wherein the correction unit (13) corrects at least one of the thermal resistance, the heat generation, and the thermal capacity at a measurement position by using measurement information including temperature (T31) or thermal flow (U32) measured by a sensing unit (8) at the measurement position in the rotating electric machine (1).

摘要： This motor device includes: a motor having components including a stator and a rotor; and a controlling circuitry to control the motor. The motor is provided with temperature sensors to detect a heat transfer amount and a transfer direction about the components. The controlling circuitry includes a temperature calculator to calculate a component temperature based on a thermal circuit network from thermal resistances and heat capacities given for the components. On the basis of actual measured values of the heat transfer amount and the transfer direction obtained by the temperature sensors, the temperature calculator corrects thermal resistances and heat capacities about the components obtained on the basis of the thermal circuit network, and estimates the temperature of each component during driving of the motor.

摘要： A heat-generating-component cooling flow passage and a bearing cooling flow passage are formed by mounting a flow passage cover to a rotor unit side of a rear bracket-cum-cooler. An arrangement region of the bearing cooling flow passage in an axial direction of the rotary shaft is arranged so as to overlap with at least a part of an arrangement region of a rear bearing in the axial direction of the rotary shaft. The heat-generating-component cooling flow passage is arranged so as to overlap with at least a part of an arrangement region of a heat generating component when viewed in the axial direction of the rotary shaft. A stator core is connected to the heat-generating-component cooling flow passage through the rear bracket-cum-cooler.
