Drive motors for conveyors are loed on the head pulley (to pull the belt). Conveyor drives consist of a motor coupled to a gear reducer, which drives the head pulley. Should the head pulley slip, because the conveyor belt is not tensioned properly, the head pulley will slip and burn through the belt.
