Abstract

PURPOSE: To reduce the high-frequency reactance and secondary resistance, by increasing the width of the cross section of a rotor groove toward the outside diameter.
CONSTITUTION: The width of the cross section of the conductor groove 1K of a rotor 1 is increased toward the outside diameter of the rotor so that the cross- sectional area of the groove is made larger than that of a half-closed groove. The high-frequency reactance and secondary resistance and thus reduced. If projections 1a are provided in the groove, a conductor can be held down against the centrifugal force when the conductor is cast.
