Regulating the speed of your belt conveyor

Supplier: Robotunits
27 June, 2011

When implementing a conveyor in your manufacturing process you need to work out exactly what speed the conveyor needs to run at to match the current manufacturing speed.

This can be either measured by looking at machines already in place or calculating proposed manufacturing cycle times. Once we know these parameters we can design the conveyor to closely match the required speeds.

By selecting different ratios within the Motor/Gearbox and also the selection of different size timing pulleys we can build the conveyor to run at a certain speed.

Of course a design like this does not allow adjustment of the speed at all, it is static. This is fine for a lot of processes were the conveyor speed is not critical. In applications were the speed of the conveyor needs to be variable a frequency inverter can be used. A frequency inverter is basically an electronic device, which changes the AC frequency to the motor and thus allowing us to adjust motor and therefore conveyor speed.

Motors are designed to work best at a certain frequency. It is therefore advisable to calculate the most likely speed required and build the conveyor with its gearbox and pulley ratios accordingly. The frequency inverter is then simply used to adjust the speed by a small amount. This is because deviations of more than 20% will result in great loss of torque and also overheat the motor.

If you need help in working out conveyor specifications for your exact needs please let us know. We will do it all for you!
