Understanding Shaft Alignment Options For Conveyor Drives

Mar 22, 2021 An alignment-free drive system almost always uses a right-angled reducer. This puts the motor alongside the conveyor rather than having it sticking out some distance from the belt. A downside of the alignment-free configuration is that the reducer and motor are suspended from the pulley shaft.
