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： PURPOSE: To suppress the increase in loss due to high harmonics and the temperature increase of a permanent magnet and at the same time improve motor efficiency by setting the gap dimension between a stator core and the permanent magnet and the ratio of the opening width of a slot to the width of a core gear part to values within each specific limited range. CONSTITUTION: The gap length between a permanent magnet and a stator core is set to 2.5mm or less and the gear width of the stator core is at least doubled as compared with a slot width to set the magnet temperature increase of the permanent magnet mounted to an outer rotor yoke to 20K or less. On the other hand, the gap length is set to 5mm or less to avoid the increased size of a motor due to the increase in the core length and the slot width of a gear width is set to four times larger than the slot width or less to eliminate the trouble in terms of manufacture of the stator due to the increase in slot depth, thus suppressing the increase in loss due to high harmonics and temperature increase of the permanent magnet and improving the motor efficiency within a range which is reasonable for the slot and an armature coil without increasing the size of the motor.

摘要： PROBLEM TO BE SOLVED: To realize a method for measuring the noise of a motor in a circumstance close to an actual operating environment by giving the motor an electromagnetic vinrating force.
SOLUTION: Each drive state impressed by different voltage as a terminal voltage without connecting a loading machine to the motor and maintaining a constant revolution speed varies the intensity of a magnetic flux for vibrating a case, and so an electromagnetic force generated in a state that the motor is in different load operation can be made. Therefore, the noise of the motor can be measured in a state close to an actual operating environment by giving the motor an electromagnetic vibrating force without connecting a loading machine, and so the noise of the single motor can be measured without using a loading machine.

Further, the steering link 39 is coupled with a steering triangle link 31 on the opposite side via a coupling link 50. Here, the steering triangle links 31, 32 are supported by steering triangle link catches projecting from the bogie frame. Similarly, an axle 6B having a wheel 1B constructs a steering mechanism. A steering connection link 51 is disposed between the steering triangle links 31, 32 which turn the wheels 6A, 6B on front and rear in opposite direction by a same amount.
