PURPOSE:To improve the stability of inserting state of a thin insulating plate and the adaptability to the shape of a coil by inserting a thin insulating plate of ring disc shape continued at the peripheral direction of a stator core formed of a synthetic resin film to between coil phases of two phases at the extension of the coil. CONSTITUTION:A thin insulating plate 20 is inserted between coil phases of extension C' of the coil from a stator core 10 of stator coils C1, C2 of 2 phases inserted into the slots 11 of the stator core 10. The plate 20 is punched in a flat ring disc shape by a relatively flexible synthetic resin film with the inner peripheral edge 21 disposed at the base side of the extension C' to be inserted to between the coils C1, C2 of the extension C'. In this manner, the extensions can be effectively held in insulated state. |
