Abstract
A dynamo-electric machine satisfies an expression EQU R.sub.eq .gtoreq.(.rho..sub.0 .multidot.(r1*.tau.)/(S/3))*(2.5) PA1 where .rho..sub.0 (.OMEGA..multidot.m) is the resistivity of armature coil, S (m.sup.2) is the cross-sectional area of the conductor portions thereof, r1 (m) is radius of rotation of the connecting portions between equalizers and armature circuits, namely the armature coil, risers, or commutator segments, .tau. (rad) is the pitch of pole pairs, and R.sub.eq (.OMEGA.) is the resistance value of the equalizer.
