You selected the right AGMA Class gearbox . You calculated the belt tension perfectly. But the moment you hit "Start," the belt snaps or the gearbox makes a terrifying clunk. The culprit is likely your Starting Method . In conveyor systems, the starting torque profile matters more than steady-state power. Note: We previously discussed VFDs as Energy Savers for pumps and fans. For conveyors, however, the goal is not lowering your electric bill—it is preventing your gearbox from exploding.

The Physics of Shock Loads When an AC induction motor starts Direct-On-Line (DOL), it draws 600% to 800% of its rated current (Inrush Current). More importantly, it produces a sudden spike known as Locked-Rotor Torqu...
When designing a machine for customers in the European Economic Area (EEA), mechanical designers must ensure the equipment has full CE compliance . It is not optional; it is a legal requirement. However, the landscape has changed significantly in recent years. With updated directives, the introduction of the UKCA mark post-Brexit, and the upcoming transition to the new Machinery Regulation , staying compliant is more complex than ever. Advertisement What is CE Marking? The CE marking stands for " Conformité Européenne " (European Conformity). By affixing this mark, the manufacturer asserts that the product meets all essential "Health and Safety" requirements of the relevant European legislation. Figure 1: The CE mark acts as a passport for the EU market, while the UKCA mark is now required for Great Britain. It acts as a "passport" for your product, allowing it to be sold freely within the EU Single Market...
