4. AC Machines The principle of operation is govern by (i) the law of electro-magnetic induction and (ii) law of interaction. (i) Law of electromagnetic induction (Faraday's 1st law): An emf is induced in a conductor whenever it cuts across the magnetic field (ii) (ii) Law of interaction: whenever a current carrying conductor is placed in the magnetic field, by the …
The construction of transformer is very simple for the small-sized transformer. It consists of a transformer core, primary and secondary windings. For a high range of power transformers, the core and windings are placed in a transformer tank with additional accessories. The main components involved in the construction of transformer are as follows

Synchronous speed is the speed of rotation of the magnetic field in a rotary machine, and it depends upon the frequency and number poles of the machine. The induction motor always runs at speed less than its synchronous speed. The rotating magnetic field produced in the stator will create flux in the rotor, hence causing the rotor to rotate. Due to the lag between the flux …
