摘要： To significantly improve a heat dissipation property of an axial gap rotary electric machine within a size necessary for configuring a motor. In an axial gap rotary electric machine comprising a stator and a rotor in an axial direction, the stator has a plurality of stator cores arranged in a circumferential direction and coils wound around the stator cores, and a heat pipe obtained by filling an inside of a metal hollow pipe with a refrigerant is arranged in a gap between adjacent coils formed in an outer diameter portion of the stator in a radial direction and a housing with a necessary insulation distance between the coils and the heat pipe. The heat pipe extends in a direction of a rotation axis and an opposite output side, and is in contact with a heat dissipating fin outside an end bracket on the opposite output side.

摘要： Provided is a cooling apparatus for an electric machine combined with an external fan or blower that includes a plurality of cooler tubes or plates spaced a predetermined distance apart within a chamber of the cooling apparatus. Internally circulating air of the electric machine flows through the cooler tubes and externally circulating air flows over the cooler tubes in a direction perpendicular or opposite that of the internally circulating air perform the cooling process. The velocity of externally circulated air is increased using cones and thus the Venturi effect is created. The fresh air enters the cooler from the adjacent openings due to Venturi effect and the total mixed air at lower temperature flows over the reminder of the tubes or plates to cool the internal circuit air, thus improves the cooler efficiency.

摘要： The torque motor in this patent depends on decreasing the gap between a surface on a fixed part and a corresponding inclined facing surface on a rotating part, where the gap width is proportional to its distance from the angle vertex, in magnifying the electromagnetic force and its resulting torque. Therefore, the surface on the fixed part starts directly at—or close to—a point in align with the rotating part center of rotation, and hence the gap width is minimum at the start point and increases away from this point due to the inclination angle. The motor may have various features such as utilizing many pairs of facing surfaces, many electromagnetic circuits; arrange the surfaces in pairs for balanced forces, works in one or two directions, the two directions electromagnetic circuits installed in one or two levels. Precautions and ways to avoid magnetic field interference and leakage should be considered.

摘要： Turbine assemblies, loss recovery systems, and related fabrication methods are provided for managing temperatures associated with an electrical generator. One exemplary turbine assembly suitable for use in a loss recovery system includes a wheel configured to rotate in response to a portion of a fluid flow bypassing a flow control valve, a generator including a stator assembly disposed about a rotor coupled to the wheel to rotate in response to rotation of the wheel, a conductive structure in contact with the stator assembly, and an insulating structure radially encompassing the conductive structure and the generator. The conductive structure accesses at least a portion of the fluid flow bypassing the flow control valve and impacting the wheel, thereby providing thermal coupling between the stator assembly and the bypass fluid flow to transfer heat from the stator assembly to the bypass fluid flow via the conductive structure.

摘要： The present invention relates to a high performance rotating electrical machine which aims at downsizing, and challenges inevitable technical problems such as deterioration of efficiency η caused by copper loss and temperature rise inside the rotating electrical machine due to heat generation induced by eddy current generated in a magnetic body. Such technical problem may be solved by configuring a coreless rotating electrical machine as comprising a stator having a cylindrical coil of a laminate structure consisting of two-layer or four-layer conductive metal sheets and a lid-type mount which fixes one of end faces of the cylindrical coil, and a rotor having a cup-type mount opposingly positioned with respect to the lid-type mount, with an air gap formed by a bottom, an inner cylindrical air-channel forming body and an outer cylindrical air-channel forming body, in which the cylindrical coil is arranged as suspended, and a plurality of magnets equipped on the outer cylindrical air-channel forming body and/or the inner cylindrical air-channel forming body, the cup-type mount has intake holes leading to the second air space on the bottom and a plurality of exhaust holes leading to the air gap, positioned in a row around a circumference of the outer cylindrical air-channel forming body, close to the bottom, and/or a plurality of exhaust holes leading to the air gap, consisting of arrays in a lengthwise direction of the air gap, from the open end face to the bottom with equally spaced intervals on the circumference of the outer cylindrical air-channel forming body, wherein ambient air taken into the second air space and/or ambient air taken into the outer side of the cylindrical coil, under differential pressure generated around the rotor by rotation thereof, are configured to directly cool a plurality of the magnets exposed in the air gap and both surfaces of the cylindrical coil arranged in the air gap, and to be discharged from the exhaust holes of the rotating outer cylindrical air-channel forming body.
