which have higher efficiency transformer or induction moter
Answer Posted / s naved masood
Transformers have higher or really speaking much higher
efficiency than induction motors because the flux linkage
in transformers is through high permiability CRGO Steel
whereas induction motors use the air gap between stator and
rotor for flux linkage which has too much reluctance
towards flux.
Mechanical loses are also effect its efficiency but the
main reason is that of medium of flux linkage
