The benefits of using VFDs - Part 2

by Paul Rudd Search Engine Optimization

In the first part of this series, we looked at some of the most prominent advantages of using Variable Frequency Drives (VFDs). Now in this second and final part, we will explore, highlight, and explain 4 more benefits of using VFDs. Again, like in the first part, this list of advantages is compiled and curated by Indexel Engineering Pvt Ltd, who are ranked among the top VFD suppliers in India, besides being one of the most trusted PLC Control Panel manufacturers and SCADA system manufacturers in India. So here are 4 more crucial benefits of using VFDs. 

Lower power requirement on start

If the power is in proportion with the product of the current and voltage (current x voltage), then you will require a greater magnitude of power to start an AC motor than you would with a VFD. the major problem with this is that certain electrical distribution systems could be operating at their maximum limit during peak hours. And when you require a greater quantity of power during peak hours for the purpose of starting an AC motor then you could be charged surged prices for the same. This, however, would cease to be an issue with VFD. 

Controlled acceleration

A VFD always starts with zero speed and then it gradually accelerates on an easily adjustable ramp. On the other hand, an AC motor that starts across the line could, or rather, would trigger massive mechanical shocks for the motor as well as mechanically connected load. Over a period of time, this shock would enhance the wear and tear on the connected load and the AC motor. Certain applications, like the ones that include easy-to-tip products (bottling lines for example), would benefit massively from a slow, steady, and smooth ramp up of power as it would enable the conveyor belt to pick up speed steadily rather than facing an abrupt jerk to full power. 

Controlled stopping

The best VFD manufacturers in India will tell you that controlled stopping is as important as controlled acceleration. Controlled stopping helps to reduce the wear and tear on machines, which often is a result of mechanical shocks. With a VFD, you would be able to stop your motor in a controlled or ramped manner.

Adjustable torque limit

Using a VFD could help protect the machinery from physical and structural damage and could also protect the product (or the process) as the amount of torque that is being applied could be controlled precisely. A good example of this would be a conveyor jam. If you only have th eAC motor connected, then the motor would continuously try to rotate till the time the overload device of the motor opens. On the other hand, a VFD could be manipulated to limit the torque amount so that the AC motor could never exceed the limit.
