Tips: Basic principle of stepper motor linear actuator
The stepper motor linear actuator is meshed with a screw and nut, so as to prevent the relative rotation of the screw nut so that the screw will have axial movement. There are two ways to achieve this transformation. The first is to build a rotor with inner screw thread in the stepper motor so as to achieve the linear motion through the mesh of internal thread and the screw. The second is to use the screw as the output shaft of the motor. A linear motion is achieved by meshing the external drive nut and screw. It simplifies the design greatly so that precise linear motion can be carried out in many application areas without installing external mechanical linkage device.

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.
