The drum motor [A] (a brushless motor) drives the drum via gears and a timing
belt. This motor also drives the cleaning unit using a timing belt [C].
This motor contains a drive controller circuit, which controls the drum rotation.
Since the drum shaft does not pass all the way through the drum from front to rear,
a flywheel [D] is mounted on the shaft at the rear of the drum to eliminate uneven
drum rotation.
