Environmental concerns and optimising energy costs are strong drivers for an end-user’s economic policy. As a consequence, Total Cost of Ownership (TCO) is an important factor when making investment decisions. System design is key to TCO and influences any purchasing decision, such as the design of a pump control system. What is Total Cost of […]
An interesting article from the Schneider Electric blog considers how integrating motor control, automation, and energy systems reduce cost and improve efficiency. In most industrial operations, electric motors play a critical role in driving conveyors, pumps, compressors, agitators, fans, and essential equipment. In large production plants, the management and monitoring of motors are critical for […]
The benefits of using VSDs with motors are well documented, however for some applications the installer must use caution. Using a long VSD cable between the drive and the electric motor can have a major impact on performance and cause premature ageing. For example, long cable runs between the drive, and motor may cause […]
The simple answer is yes. You can run multiple motors with a single VSD, provided they all need to run at the same speed. There are many advantages to this arrangement as a way of reducing system cost and complexity. Some factors need consideration when designing the system. VSD with multiple motors The main […]
Should you choose a soft starter or VSD for controlling conveyor motors? For most motor drive applications, the choice between VSDs and soft starters is clear cut. But for conveyor applications, either option may be suitable, and selection is a balance between price and performance. Soft starters Soft starters slowly ramp-up the motor to minimise […]
