Abstract

PURPOSE:To improve the insulation performance at the secondary lead wire and to facilitate the assembly of winding by providing common shieldings at a shunt winding and the lower section of a series winding which are arranged at the same core of an iron core wherein a lead wire is passed between the common shieldings and the lower section of the series winding. CONSTITUTION:United common shieldings 41 are provided at a shunt winding 3 and the lower section of a series winding 4 which are arranged at the same core of an iron core and the shieldings 41 supply the electric potential around the lower section of the winding 3 and the connection section of the winding 4. Shields 6, 7 supplying the electric potential at each end section of the windings 3, 4 are provided at the upper sections of the windings 3, 4. And the lead wire 14' of the winding 3 is horizontally led out through a gap between the shieldings 41 and the lower end of the winding 4. And the influence from the grounding electric potential such as the lower frame 10 or the like is shielded and isolated by the shieldings 41. In this way, the insulation performance at the secondary lead wire will be improved and the assembly of wiring will also be facilitated.
