Tips: Basic Structure of Induction motor

The main structure of induction motor is composed of two parts stator and rotor where there is an air gap between them. In addition, there are end bells, bearings, motor frame and other components.

stator
Stator is a fixed part of asynchronous motor, consisting of motor frame, iron core and windings. Motor frame is the shell of motor, playing the role of supporting the motor, which is made of iron. Stator iron core is a hollow cylinder, stacked up with 0.5 mm thick silicon steel sheets. Stator windings are wound with insulated copper wires and embedded in the stator slot, which are separated by insulating material between the windings and the slot.
Air gap
The air gap of asynchronous motor is much smaller than the direct current motor with the same capacity, 0.2 ~ 1.0mm on average for medium and small asynchronous motor.
Rotor
Motor rotor is composed of iron core, windings and revolving shaft. Rotor core is also a part of the magnetic circuit, generally stacked by silicon steels and fixed on the revolving shaft. Wound-type rotor winding can be connected into star or delta. In general, the small capacity rotor is connected into triangle; the large and medium capacity one is connected into star. The winding structure of squirrel-cage rotor is quite different from the one of stator. There are slots on the rotor iron core with a bar on each slot. Two ends of iron core that connect all the bars to the external of slots respectively form a short circuit. If the iron core is removed from the stator, the windings shape is like a squirrel cage. Some bars are made of copper, and some are aluminum.

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.
