Abstract

PURPOSE:To improve the corrosion resistance of an air gap, by a method wherein a labyrinth seal is composed by a rotor core and a bracket or a hole in which surface protecting material such as grease is filled is provided in an iron junction. CONSTITUTION:The end of a cylindrical supporting member 66 which is coaxial with a yoke 30 connecting between nails of the same polarity of a rotor core 22 is extended to a rear bracket 18 and is made an annular shape. A part of the rear bracket 18 is protruded to the side of the rotor core and forms a circular protruded portion 68. The diameter of the protruded portion 68 is larger than that of the extended portion of the supporting member 66 and their axes are common so that they overlap each other with a certain interval to compose a labyrinth seal 70. This, an air gap g2 is protected by the labyrinth seal 70 and foreign materials such as moisture, salt and so forth are prevented from penetrating into the gap g2 so that the corrosion resistance of the gap g2 is improved and the reliability of the generator is increased.
