Nowadays, many belt conveyors are equipped with VSDs, where the VSD based optimal control strategy can be applied. For a belt conveyor with VSD, its power at the jth sample time can be expressed as P i j = f P (V i j, T i j) according to (3). Combining P i j with (5), we obtain the total electricity cost as follows (10) J = ∑ i = 1 n ∑ j ...

By executing and checking off steps as you take them, you can clearly identify which step (s) corrected the problem. Third, whenever possible let the VSD help you pinpoint the problem. Most drives have fault history tracing, which is extremely helpful in narrowing down the issue.
This improves processes, conserves energy, and extends the life of conveyor equipment. Soft starters and VSDs both achieve efficiencies of over 90%, although other factors may affect this efficiency. When operating at full speed with a light load, soft starters are more efficient than VSDs. At full speed, their integrated bypass allows current ...

Conveyor belts resemble a band or loop of rollers connected to rotors powered by a motor. The belts can be as narrow as one inch (25 mm) or as wide as five feet (1.5 m), with plastic modular belts as wide as ten feet (3 m). Conveyor belts are made of highly durable and sturdy materials, much like heavy-duty machinery.
Due to the proper speed control, there won't be any jerks in the conveyor or in the belts. So because of the VSD equipment life can be extended and also the maintenance will be reduced.

It is certainly advantageous, for example, to have torque limiting on a conveyor belt motor, so that the motor does not apply full rated torque (i.e. stretching force) to the belt during start-up. ... In order for a VSD or VFD to properly and safely control an electric motor, that drive must be programmed with the motor's nameplate data ...
In general, variable speed drives are used to: Latch the speed of a drive to the process requirements. Latch the torque of a drive to the process requirements. Save energy and improve efficiency. The needs for speed and torque control are usually fairly obvious. Modern electrical VSDs can be used to accurately maintain the speed of a …
VSD. Larger belts require more power and this has brought the need for larger individual drives and for multiple drives such as four drive units of 1000 kW each on one belt. After the power on a conveyor belt is calculated, a decision can be taken whether the belt should be fitted with single or multiple drives.
