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 […]
Avoiding unplanned downtime of rotating machinery is an important tool for improving the productivity of manufacturing. Modern VSD’s offer a wide range of functions to protect both the drive and connected motor. Adding a condition monitoring system extends this protection to critical fans, pumps, gearboxes and other equipment. The condition-based monitoring solution developed by Mitsubishi […]
An overload in a motor circuit can take several forms. For example, an overcurrent fault due to a short circuit or earth fault, or motor overload. It raises the question “Does my motor need an overload relay and VSD?” Each fault type needs different handling, and the type of protection depends on the needs of […]
