    摘要： In a rotary electric machine, a stator coil includes in-slot portions each contained in a corresponding one of slots of a stator core. The stator coil includes turn portions each connecting one end of a corresponding one of the in-slot portions projecting from one axial end of the stator core with one end of a corresponding alternative one of the in-slot portions projecting the one axial end of the stator core. The turn portions provide an end portion of the stator coil. A coolant guide is placed to cover a circumferential outer part of the end portion of the stator coil from radially outside thereof and provided with holes therethrough. The coolant guide guides a coolant therealong in a circumferential direction of the end portion of the stator coil while guiding, through the holes, a part of the coolant to the end portion of the stator coil.

    摘要： In a rotary pump in which axial end surfaces of outer and inner rotors is in pressurized direct contact with an axial end surface of a second side plate to form a mechanical sealing, both of the axial end surfaces of the outer and inner rotors and the axial end surface of the second side plate are provided with radial line grinding stripes. Teeth gap portions formed by the outer and inner rotors in mesh communicate with an outer circumference gap between the circumference of the outer rotor and inner circumference of a center plate and also with a shaft hole of the inner rotor through extremely slight gaps formed by concave and convex of the radial line grinding stripes so that contact surface between the outer and inner rotors and the second side plate is well lubricated to reduce torque loss.

    摘要： A rotor includes a rotor core and permanent magnets each of which is received in a corresponding slot of the rotor core with its magnetization direction being oblique to a radial direction of the rotor core. Each of the permanent magnets has a first corner portion positioned radially outermost and a second corner portion positioned radially innermost. For each of the permanent magnets, there are formed first and second gaps respectively between the first corner portion and the inner surface of the corresponding slot and between the second corner portion and the inner surface of the corresponding slot in a reference direction of the permanent magnet. The rotor core also has, for each of the permanent magnets, supporting portions each of which abuts and thereby supports, in the reference direction, a predetermined portion of the permanent magnet which is positioned away from both the first and second corner portions.

    摘要： An electric rotating machine includes a stator, a rotor, and a housing. The stator includes a stator core and a stator coil formed by laminating magnetic steel sheets. Each of the magnetic steel sheets has through-holes that are formed to penetrate the magnetic steel sheet in the axial direction of the stator core. All of the magnetic steel sheets are divided into groups each of which includes axially-adjacent n of the magnetic steel sheets, where n is an integer not less than 2. For each of the groups, corresponding n of the through-holes of the n magnetic steel sheets of the group communicate with one other to form an inside coolant passage. The inside coolant passage fluidically connects an outside coolant passage, which is formed between the housing and the radially outer surface of the stator core, with a corresponding one of the slots of the stator core.

    摘要： The curvature of a circular arc constituted by a side of a suction groove is made larger than that of a circular arc constituted by a side of a discharge groove. Thus, when the suction groove and the discharge groove are viewed in the axial direction of a drive shaft, the distance between the suction groove and the discharge groove in the radial direction of a rotary portion is short in a region intersecting with a line W perpendicular to a centerline, and increases in accordance with a decrease in distance from containment portions. It is therefore possible to ensure a sufficient distance between the discharge and suction grooves and enhance a total fluid pressure generated therebetween, and the contact surface pressure that is necessitated by a second side plate to obtain a press-back force when being in contact with an outer rotor and an inner rotor is reduced.

    摘要： In an inner wall surface of a casing, grooves are formed that correspond to end faces of an outer rotor and an inner rotor, and seal members are disposed within the grooves, the seal members presses against the end faces of the outer rotor and the inner rotor. Inclined portions are provided in sealing portions of resin members of seal members, the sealing portions covering a closed portion. With this configuration, an internal pressure in the closed portion causes the inclined portions to separate from an outer rotor and an inner rotor when a brake fluid pressure within the closed portion increases to the point that the brake fluid is excessively compressed, releasing the brake fluid that is inside the closed portion. It is therefore possible to prevent the brake fluid pressure from increasing excessively within the closed portion.
