Tips: VFD vs Soft Starter in high starting torque application
Variable frequency drive (VFD) solution will solve in most cases the torque problem when using standard induction motor. Soft starter that reduce the toque might not deliver the required torque in effort to get to full speed. VFD with vector control is able produce higher torque in induction motor shaft than star delta or soft starter while also drawing less current from the power supply. This way you can have high torque during start, low current and after getting into full speed you bypass the VFD and save all the energy loses and noises that VFD caused.

If starting torque is not an issue in the installation, the start delta or soft starter are both OK. If you want to limit current rush in start or jam situation or you want to get higher starting torque then vector control VFD is a good selection and even better if closed loop with speed feedback from motor to VFD. Energy saving with VFD is achieved due to better control of magnetizing and rotor currents. It optimizes total current to motor thus reduces motor (and network) losses caused by excess current.

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.
