Coil insertion apparatus.

摘要

A coil insertion apparatus (F) for inserting coils (8), for example into stator cores (6) of electrical rotary machines, in which blades (5) and a coil pusher (9) of this apparatus (F) are arranged to be movable at optimum timing and speed suitable for various winding specifications of stators so as to make it possible to efficiently insert coils (8) having low coil ends and short circumferential lengths into stator cores, with simultaneous reduction of coil inserting resistance. The blades (5) are divided into bladegroups (10,11) each secured to a corresponding blade holder (12,13). The blade holders (12,13) abd the coil pusher (9) are respectively provided with driving sections (15,16,29) which are independent of each other.
