Leakage reactance of polyphase machines - Design of Induction Motors

Leakage reactance = 2πf x inductance = 2πf x Flux linkage / current

Leakage reactance of polyphase machines

 

Leakage reactance = 2πf x inductance = 2πf x Flux linkage / current

 

Note:

 

1.                   Useful flux: It is the flux that links with both primary and secondary windings and is responsible in transferring the energy Electro-magnetically from primary to secondary side. The path of the useful flux is in the magnetic core.

 

2.                     Leakage flux: It is the flux that links only with the primary or secondary winding and is responsible in imparting inductance to the windings. The path of the leakage flux depends on the geometrical configuration of the coils and the neighboring iron masses.
