Abstract
Provided are an insertion method and an insertion apparatus for efficiently and reliably inserting a plurality of coil elements aligned in a ring shape into respective slots of a stator core. In an insertion method of inserting, the insertion method includes a coil element alignment process S3 of forming an assembly body 50 by assembling the plurality of coil elements 40 in a ring shape in the state where the turn portions 42 alternately overlap each other, a supporting process S42 of supporting the assembly body 50 by using the turn portions 42, and an insertion process S45 of allowing the assembly body 50 and the stator core 60 to be close to each other and inserting the leg portions 41 of the coil elements 40 of the assembly body 50 into the slots 61.
