Tips: Do I need a VFD?
First question is about load speed / torque profile. If load need large speed variation, variable frequency drive (VFD) come with significant energy saving, if not, may be difficult to sustain VFD cost/ investment. First candidates to VFD are pump / fan systems. VFDs do provide some advantages, but there are also some disadvantages as well, like harmonics injection, motor insulation premature fails, cable reflection for lengths more than 10m. These issues must be controlled / put in balance. So, there are not advantages only by using a VFD.

For sure VFDs are big energy enablers. Yet official data announced that only 10 to 20% of motors are equipped worldwide. And even with new motor classes, we will not reach the same level of savings. The trend is now motor being embedded intelligence for energy savings, this push VFD manufacturers enhance the saving rates of the VFD. Finally, people and earth will benefit of their capabilities.

For the area where there is only single phase power supply available but you have three phase plant, in case of less than 5 HP, by far the most efficient and easy way to convert single phase to three phase are the variable frequency drives out that can be equipped with single phase front ends, and provide variable frequency three phase power. I have one 5hp VFD on my water pump and could not be happier, not just for the ability to use a three phase motor, but also soft start, dynamic breaking, speed control, and direction control.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
