VFDs and Soft starter have commonality in features however, VFDs offer more functions compared to Soft starters, particularly continuous modulation of Speed and Torque. Though VFDs may be capable of implementing more complex task, this doesn’t mean that VFDs are always the ideal option. Selection highly depends on the suitability and adherence to the selection factors mentioned in this article.
Allen Bradley’s VFD solutions cover a wide range of sizes and applications for any control and automation needs through its PowerFlex® VFD family. The PowerFlex® family of drives is divided into low voltage and medium voltage solutions depending on size, scale and complexity of system requirements. Low voltage VFDs are divided into two categories, compact and architecture class.
While there are many options for VFDs from a variety of manufacturers, there are many things to consider when choosing a new VFD. These include motor considerations, VFD selection and how the VFD can or should integrate with PLCs.
The electric motor represents a crucial part of any electrical drive system. Without the electrical motor, the whole system wouldn’t function. However, in order to work properly, even the most advanced motor needs some kind of controller. Usually, system designers and engineers take advantage of a VFD (Variable Frequency Drive). Choosing and purchasing the right…
Servo systems are now well-known for their use in CNC machining, robotics, and factory automation. The servo technology is further expanded with the manufacturing of servo drives, used for powering electric servomechanisms. Despite being an excellent option for industry use, we also have these VFDs (Variable-Frequency Drives) which tend to be used a lot as…
