Abstract

PURPOSE: To control an increase of the leakage reactance in a rotor winding by coating a magnetic wedge with a conductive frame body consisting of non-magnetic material whose path direction of a leakage magnetic field passing through the magnet wedge is opened.
CONSTITUTION: The exterior surface of a magnetic wedge 5 is coated with non- magnetic excellent conductive material 9 in the direction in which it intersects with leakage magnetic flux ϕ3. When the leakage magnetic flux ϕ3 caused by the current applied in a rotor winding passes through the magnetic wedge 5, current is applied to the conductive frame 9 in the arrow direction and the leakage magnetic flux ϕ3 is decreased. As a result, the leakage reactance of the rotor winding 4 can be reduced and output be increased
