    • A stator coil heating apparatus and a stator coil heating method that are capable of effectively preventing a core from thermal deformation particularly caused due to a magnetic flux generated by a coil head, without the problem of heating temperature variation, and also shortening a time for the process of heating a stator coil, are provided.
      A stator coil heating apparatus A to heat a stator coil L wound around a circular core F, comprises: induction heating coil heads 1 and 11 that heat the circular coil L by generating an inductive effect acting from outside in the thickness direction of the core F, against circular winding coil bases La and Lb that are sticking out of end faces Fa and Fb of the core F in the thickness direction thereof; and shields 2 and 12 that block a magnetic flux generated by the coil heads 1 and 11, out of the end faces Fa and Fb of the core F in the thickness direction thereof.
    • 一种定子线圈加热装置和定子线圈加热方法,其能够有效地防止由于线圈头产生的磁通而引起的芯的热变形,而不会导致温度变化的加热,并且还缩短了时间 提供加热定子线圈的过程。 用于加热缠绕在圆形芯F上的定子线圈L的定子线圈加热装置A包括:感应加热线圈头1和11,其通过产生从芯部F的厚度方向的外侧起作用的感应效应来加热圆形线圈L 针对从芯F的厚度方向的端面Fa,Fb伸出的圆形卷绕线圈座La,Lb, 以及将线圈头1和11产生的磁通阻挡在芯F的厚度方向的端面Fa和Fb中的屏蔽2和12。
