The drive from the main motor [A] is transmitted to the drum [B] through a series of
gears, a timing belt [C], and the drum drive shaft [D]. The main motor has a drive
controller, which outputs a motor lock signal when the rotation speed is out of the
specified range.
The fly-wheel [E] on the end of the drum drive shaft stabilizes the rotation speed
(this prevents banding and jitter from appearing on copies).
The A232 has two flywheels because of the higher speed.
