This is the powerhead (power nozzle) motor for the E2 Black vacuum.
(You have an E2 Black if your canister has led lights which shine into the water basin.)
There are two versions of motors in these powerheads. This is the version in which the belt rides in the center of the brushroll, referred to as the "center pulley" version.
