a synchronous motor with negligible armature resistance runs at a load angle of 20 degree at rated fequency. If we increase supply frequency by 10% keeping other parameter constant, wht will be new load angle?
this is the question which is bothering me, i know the effect of changing excitation but how is load angle dependent on frequency? please clear my doubt…
if FREQUENCY chnage SPEED will chnage then INDUCED E.M.F and LOAD ANGLE will be changed
I too have the same doubt…… u just answered dat load angle is effected …. kindly explain how is it affected??? i mean whether it is increased or decreased??nd how?
