ng connections. Re-entrancy of Wiiidings. An armature winding which closesupon itself, i. e., returns to its beginning, is known as a closed-coilarmature winding, and since such a winding re-enters itself it iscalled re-entrant. Armature windings may be singly, doubly, or midtiply re-entrant.A… … o H<!
