Abstract

PURPOSE: To reduce leakage magnetic flux loss by forming a magnetic shielding plate which is mounted on the inner wall of a tank with a number of layers and a block with slits on a small scale as a layer of the magnetic shielding plate arrives at the layer located at the electric apparatus main body side from the layer near the tank side.
CONSTITUTION: A block 15 with slits 14 is formed on a small scale as each layer of the thin magnetic plate in a magnetic shielding plate 4 arrives at the layer near a tank 1 and that near an electric apparatus main body 6. This permits eddy current density to be reduced in the electric machine main body 6. As a result, the loss of the magnetic shielding plate and windings which was conventionally larger can sharply be reduced.
