1901 S. Sheldon & H. Mason Dynamo Electr. Machinery iii. 47 Any closed-coil winding, single or multiple, may be singly or multiply re-entrant, the re-entrancy being reckoned as great as that of any single winding on the armature.
1902 Jrnl. Inst. Electr. Engineers 31 iv. 933 A few writers..take the re-entrancy as being the number of times we must go around the armature in tracing out the whole winding.
