Tips: Asynchronous motors versus synchronous motors
1. Principle
Induction motor refers that under the effect of two magnetic fields both the rotating magnetic field generated by alternating currents access to stator and the magnetic field produced by the rotor affected, the rotor rotates with the rotating magnetic field of stator. The magnetic field of rotor is slower than the one of stator thus there is a slip. Due to its non-synchronous, it is called as asynchronous motor.
Synchronous motor refers that under a constant magnetic field formed by man-made direct current the rotor synchronously rotates with the rotating magnetic field of stator.
2. Structure
Stator windings are the same between synchronous and induction motor, but the main difference is the rotor structure.
For the synchronous motor, as for DC excitation windings of rotor, the current is introduced by slip rings under the effect of external excitation power supply. Since rotor windings of induction motor is short-circuited and the current is generated by electromagnetic induction.
3. Usage
Synchronous motors are mainly introduced into large size generators, while almost all induction motors are run in electric motors.

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.
