Potential difference relief structure inside high tension stator coil of electromotive machine

摘要

Active potential difference relief structure (40) is offered in inside the stator coil of the electromotive machine. The coil wire (22) it is full in the surface and the underside of the layered product and the filler (44) distribution facilities is possible to do. Potential difference relief structure to have is full and electric insulating formation (46) is possible on the filler, in addition, with respect to electric insulating formation conductive layer (48) furthermore to have is possible. The electric conduction bar (50) it lays out with respect to many conductive layer. The electric conduction bar the coil wire (22) at least is jointed by one electrically, shunt does the capacitance effect with conductive layer and the coil wire layered product, at the same time, mandatorily, the coil wire layered product and designates conductive layer, as same electric potential level substantially, because of this, evades overvoltage state.
