The eddy current loss in an a-c electric motor is 100 watts at 50 Hz. Its loss at 100 Hz will be
(A) 25 watts
(B) 59 watts
(C) 100 watts
(D) 400 watts
Explanatory answer:
Eddy current losses is proportional to square of frequency
( f^2)
In thise case frequency is doubled, so the New loss proportional to (2f)^2
New loss is proportional to 4f^2
Eddy current loss at 100 HZ is = 4 times greater
= 400 watts
(A) 25 watts
(B) 59 watts
(C) 100 watts
(D) 400 watts
Explanatory answer:
Eddy current losses is proportional to square of frequency
( f^2)
In thise case frequency is doubled, so the New loss proportional to (2f)^2
New loss is proportional to 4f^2
Eddy current loss at 100 HZ is = 4 times greater
= 400 watts
AC Electric Motor is really worth appreciable...
ReplyDeletenice post..people always have some confusion between AC Electric Motor and Electric DC Motor..this takes out everything.
ReplyDeletethanks bro. sorted out my confusions.
