Tips: Summarize some important information of the impact on cable size of a motor
1) Always check the wiring to match the load profile - see motor nameplate data.
2) All motors are not created equal. If the motor is not rated for use with VFD, it is certain to fail quickly and dramatically, either by failure of insulation (and arc to chassis / ground) or by bearing failure due to circulating currents. So if it is not rated for VFD, don't use it with a VFD.
3) All cables are not created equal. VFDs produce voltage spikes in the order of 1600-2000V while artificially generating the desired sine wave that drives the motor. This is 2-4x the rating of most electrical wire insulation. If the wire is not rated for this voltage, it will quickly fail, allowing the voltage to ACR to nearest conductor (or personnel) with dangerous or deadly results.

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.
