ABSTRACT:
According to the invention electrically conductive paths are provided between the coil armor and the core laminations of dynamoelectric machines by placing a semiconducting elastomeric material between the coil sides and the walls of the core slots. The elastomeric material is of a type which has a controlled resistance and will deform sufficiently under pressure to flow into the irregularities between the coil side and the slot walls, and in so doing provide conductive paths for electric charge to flow from the armor to the core laminations. This material must be capable of retaining its strength, elasticity, conductivity, etc., and remaining in place between the coils and core under vibration, coolant flow, electric stresses, repeated temperature changes, etc., for the operating life of the machine. Preferably, these paths will be heat conductors as well.
