PURPOSE:To obtain the large capacitive armature of small iron loss being easy to commutate by a method wherein plural armature windings are prepared, the under part of windings of one group are inserted into core slots, and windings of another group are held between the projecting parts of the windings of the former group out of the slots. CONSTITUTION:The plural armature windings 15, 16 are prepared. Shallow slots 14 are formed preliminary at an equal interval on the surface of the armature core 13, and the under part of the armature windings 15 of the one group are inserted into the slots 14. The armature windings 16 of another group are arranged on the surface of the armature core 13 between the armature windings 15 projecting from the slots 14, and are fixed tightly by a tightening insulator 17. Accordingly the sectional area of the armature core 13 becomes to be small to reduce the iron loss, and the commutation becomes easy in accordance with the reduction of armature reactance. Because the transmission of torque can be performed strongly, said armature can be applied to a large capacitive machine. |
