摘要： PROBLEM TO BE SOLVED: To provide a fully closed rotating electric machine capable of attaining maintenance saving by restraining a temperature increase at a bearing part and preventing early deterioration of lubricating grease, thus extending a non- disassembly period. SOLUTION: In this fully closed rotating electric machine 1 which supports a shaft 9 by the bearings 5, 7 so as to be rotatable, thermal insulation layers 12a, 12b are provided at a surface coming into contact with inside air in supporting parts 6, 8 of the bearings 5, 7. The amount of heat which is generated in the fully closed rotating electric machine 1 and transmitted to the bearing supporting parts 6, 8 by heat transfer via the inside air is reduced by thermal insulation layers 12a, 12b to minimize the increase in the temperature of the bearing supporting parts 6, 8 and the bearings 5, 7. It is thus possible to prevent the lubricating grease of the bearings 5, 7 from deteriorating early, and extend the non-disassembly period for maintenance saving. Moreover, since this method can be used merely by making thermal insulation materials 13a, 13b adhere to a surface coming into contact with the inside air in the bearing supporting parts 6, 8, it is thus possible to facilitate the use of this method for a conventional fully closed rotating electric machine.

摘要： PROBLEM TO BE SOLVED: To provide a totally/enclosed main motor for a vehicle which enables improvement in cooling effect and service life prolongation. SOLUTION: Four grooves 1b are formed in the central part of the lower end of an outer cylindrical frame 1A in the direction perpendicular to a rotor axis, i.e., in the direction parallel to the running direction of a vehicle to cause a stator core 2 to be partially exposed. The lower parts of radiation fins 1a, protruding from the outer circumference of the outer cylindrical frame 1A, are also horizontally cut off at positions slightly higher than the lower ends of stands 18. As running wind produced by the running of the vehicle is made to flow through the grooves 1b, the stator core 2 is directly cooled by the running wind partially. Furthermore, the position of the lower end of the outer cylindrical frame 1A is lowered and its diameter can be increased to enable capacity increase.

摘要： PURPOSE: To see that a rotor does not break even if an end ring and the vicinity of the soldering part of a rotor bar are pulled to the side of periphery by the centrifugal force, etc., at rotation of a rotor. CONSTITUTION: Stamped plates 1 made of silicon steel plates are stacked around a rotor shaft 2 made of steel, and a rotor bar 3 made of brass is inserted in the hole bored in the plates 1. An end ring made of oxygen free copper is provided with a recess 5 for storing fused solder material. Flux 6 for soldering is applied in the recess 5 and at the end of the rotor bar 3. A solder material 7 made of bent bar-shaped silver solder is inserted into the end of the rotor bar 3. The end ring 4 is rotated, using a rotating stage 9. At the point of time when the end ring 4 reaches about 800 deg.C by the heating of a burner 10, the rotor bar 3 is stuck fast to the recess 5 of the end ring 4, and the temperature of soldering is raised. After the solder material 7 gets wet, the heating is stopped and the whole rotor is cooled naturally.

摘要： PURPOSE: To prevent a bolt, which fastens aluminium material or copper mate rial, from loosening. CONSTITUTION: The diameter of a hole for a bolt 3 for fastening the periphery of a lid 2 is machined to a fitting hole 2b of a large diameter. A cylindrical part 8c of a fastening seat 8, whose section is of a T-shape and which has a bolthole at its central part, is inserted into this fitting hole 2b. Machining is conducted in such a manner that the thickness of a peripheral part of the lid 2, into which the bolt 3 is inserted, is slightly shorter (thinner) than the length of the cylindrical part 8c of the fastening part 8. Even in a case where the coefficient of thermal expansion of the material for the lid 2, e.g. aluminium or copper, is large, the bolt 3 does not loosen: In winter time, for example, it will suffice for the purpose only by tightening the fastening seat 8, while, in summer time, although the face pressure between a fastening surface 2a of the lid 2 and the lower surface of a flange part 8a of the fastening seat 8 increases, an excessive creep can be avoided owing to a wide contact area of the lower surface of the flange part 8a.

摘要： PURPOSE:To prevent dust and dirt contained in the atmosphere from penetrating into a rotor and a stator by a method wherein a wind path which sucks the atmosphere by the rotation of a fan through its space part which is provided between the fan and a side plate or a cover plate and discharges the air from its duct which is provided on the outer circumference of a frame in parallel with the axial direction of the frame is provided. CONSTITUTION:A wind path 20 of a cooling wind which sucks the atmosphere by the rotation of a fan 14 accompanying the rotation of a shaft 8 through a suction inlet 16 into a space part 13 and sends out the air into a duct 18 through an exhaust outlet 19 and discharges the air outside from the duct 18 is provided. As a result, the heat of a rotor 12 side is transmitted to the fan 14 through the contact plane A between the rotor 12 and the fan 14 and is radiated by the cooling wind of the fan 14 and the heat of a stator 4 is transmitted to a frame 1 through the contact plane B between a stator core 2 and the frame 1 and is radiated by the cooling wind flowing through the duct 18 to avoid the overheat of a rotary electric machine 21. Moreover, as the atmosphere does not flow inside the stator 4 and the rotor 12, the penetration of dust and dirt into the stator 4 and the rotor 12 can be avoided.

摘要： PURPOSE:To suppress high frequency noise, to be produced through amplification of the sound of high pressure pulsating air flow, by forming a plurality of sound paths, for guiding the sound of cooling air fed through a cooling air path in the peripheral direction of frame, in a space delimited by the outer peripheral surface at the coil end part and the inner peripheral surface of the frame. CONSTITUTION:A sound guide mechanism comprises a group of sound path composition members comprising a plurality of sound guide boards 22 and a plurality of sound path composition members 24 arranged between the sound guide boards 22. Sound of cooling air fed through a vent 14 in a rotor core 9 is guided in the peripheral direction of a frame l by means of the sound path composition members 24 and the axial length of each member 24 is made longer gradually toward the frame l with respect to the coil end 4a side. Since the reciprocal path of sound has different length, noise is not amplified at a specific frequency and thereby high frequency noise is suppressed.

摘要： PURPOSE:To make the noise during rotation small and enlarge output by arranging an acoustic wave amplification preventive member at the position where the distance from the periphery of a stator coil becomes not more than the half of the wavelength of an acoustic wave arising by the pulse air current of the frequency of the number that the number of rotor bars is multiplied by the revolution of a rotor. CONSTITUTION:A sound isolation plate 50 is arranged at the position where the distance l between the inwall of a frame 4 and the periphery of a stator coil 12 becomes smaller than 0.5 times the wavelength of an acoustic wave or at the position where it becomes larger than 1 time. In other words, the sound isolating plate 50 is arranged at the position of the distance l1, which is generally fairly smaller than the half of the wavelength of the acoustic wave having a certain frequency, from the periphery of the stator coil 12. Hereby, high frequency noise by a motor itself rotating at high speed, caused by the cooling wind for cooling the induction motor, is filtered.
