ABSTRACT:
An improved frame supported resistor grid used for dynamic braking of electric motors is provided. The resistor grid has a metal frame and fan-folded strips of resistance material arranged in columns within the frame. The strips of resistance material are supported by studs affixed to the folds of the strips and the studs are, in turn, supported in ceramic bushing insulators. An intermediate member is affixed to the frame and receives the individual ceramic bushing insulators.
