ABSTRACT:
A novel armature of an electric rotating machine is disclosed. The armature core is divided axially into two or more members. The coils of the armature winding are fixed on the armature core in such a way that two or more coil sides are disposed in each slot of one member, and the coil sides disposed in the same slot are arranged in adjacent different slots of the other member. The end of each coil is positioned in a manner to substantially equalize the mutual inductance between each pair of adjacent coil ends.
