The 101 model Butt-Shaft Type 11 armature is intended for a butt-shaft connection, essentially serving as a clutch-coupling connecting two independent shafts. The input shaft connects to the rotor half of the clutch, while the armature connects to the output shaft, or vice versa. Please refer to the instruction manual during installation, as this device requires a pre-set air gap along with and perpendicularity / run-out tolerances for proper operation.
