電動機械の固定子及び固定子構成部品並びにそのジュール加熱を抑制する方法

Japanese Patent JP5683074

B2

A stator component (62) whose composition and processing enable the component (62) to axially compress magnetic sheets (54) of a stator (50) and also inhibit joule heating of the component (62) to the extent that the need for a separate flux shield (28) can be eliminated. The component (62) is formed of a ductile iron alloy containing, by weight, about 3.25 to about 3.40% carbon, about 3.70 to about 3.80% silicon, about 4.50 to about 4.70% nickel, up to about 0.20% manganese, up to about 0.06% magnesium, less than 0.02% phosphorus, less than 0.02% sulfur, with the balance being iron and incidental impurities. Following heat treatment, the component (62) exhibits properties that inhibit joule heating of the component (62) by eddy currents induced by alternating magnetic fields of the stator (50).
