Tips: Using VFD to improve motor efficiency
The induction motor system will be more efficient on a variable frequency drive (VFD) than a soft starter. If you have a 6-pulse VFD the inefficient motor will look like 98.5% efficient, on an 18-pulse VFD it will look like 96.5% efficient. The DC bus of the VFD can supply the VARs to the load making it look all the more efficient. VFDs are great for making poor power factor motors look better but really do not make sense if you just run at 100% speed due to you will have the conversion losses.
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.
