The Armature and Fan Assembly, 115V, B2, GS is a replacement part designed for the American Sanders B-2+ Edger Upper Assembly. This OEM component is essential for maintaining optimal motor performance, ensuring proper torque, speed, and thermal regulation during operation. It includes both the armature and cooling fan, critical for preventing overheating during extended use. This assembly is commonly used by flooring contractors and repair technicians when the edger shows signs of underperformance, unusual noises, or overheating—often indicating worn motor internals. Replacing the armature restores the machine to like-new condition.
