Tips: How to change the rotation direction of three-phase induction motor?
As shown from the working principle of induction motor, the rotation direction of motor rotor is determined by the direction of rotor affected by the electromagnetic torque. However, the direction of electromagnetic torque depends on the direction of stator rotating magnetic field. That is to say the rotation direction of rotor is the same as the one of stator rotating magnetic field. Nevertheless, the direction of the rotating magnetic field depends on the phase sequence of three-phase power supply that has access to the three-phase windings of stator. The direction of rotating magnetic field also changes with the one of phase sequence. Therefore, simply changing the phase sequence of three-phase power supply that has access to the three-phase windings of stator can change the rotation direction of motor. This simple method is realized by connecting any two-phase power wires of three-phase power supple wires into motor.

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.
