in a salient pole machine the air gap is not constant unlike cylindrical pole machines.therefore the reluctance changes with rotor position being lowest at the polar position & min at the interpolar region.therefore a reluctance torque develops in addition to the alignment torque.so power developed in a salient pole machine is more whereas in a cylindrical pole machine the reluctance remains the same & so the only torque developed is the alignment torque &becoz of that the power developed ia cylindrical machine is less than a salient pole machine.

I have about Two year  experience three months in
power plant, have done erection, testing and
commissioning of power transformer & LT,HT Panel board
Autocad designing& testing while achieving excellence
and quality of work.I am an excellent team worker and
a fast excellence learner with an eagerness to explore
new technologies.

IN SALIENT POLE   SYN. ALTERNATOR IT  IS  THE  CHANGE  IN  THE RELUCTANCE  WITH SPACE  WHICH  RESULT  IN  GENERATION  OF  BOTH  RELUCTANCE  POWER & ELECTROMAGNETIC  POWER.
