Isn't core loss directly proportional to the square of frequency so by the formula of eddy current loss, as frequency is less than rated frequency, should'nt core loss decrease

5. A 10 kW, 400 V, 4 pole delta-connected squirrel cage induction motor gave the following test results: No-load test Blocked-rotor test : 400 V, 8 A, 250 watts. : 90 V, 35 A, 1350 watts. The d.c. resistance of the stator winding per phase measured immediately after the blocked rotor test is 0.6 2. Calculate the rotational losses and the equivalent circuit parameters. Can anyone send me solution of this question??

Thank you sir for this very easy to understand video.
@17:09 Point P is unstable as Tm >TL , w increases and disturbance was increment in speed.
Point Q is stable as Tm >TL , w increases
+1
Yeah I think he got confused
thank you so much kreatryx channel...Love you sir ji❤❤❤
Well the answer is right, just exchange the load torque and motor torque curve
sir 17:12 min pe TL wala curve Tm se chota h
Yuppp
Stable q hoga
Haa Bhai sahi bola
Sahi pakde hai
Sir last question me at point P TL
17:50 idhar kuch dikkat h ya main samajh nhi pa rha hun
isse pehle hum speed badha kar omega dekhte the now we took decreased speed so omega also decreased.. hence cant be stable
@@KunaaaaaaL bhai 17:17 me Tm zyada hai na TL se ? Neche wale point pr dekko ek baar
Thank you so much sir......
17:00 -18:42
Point P & Q both are stable
very useful...thanku sir
thank u sir
Awsm

19:20 me kya bola riddle
@17:12 I think TL
Isn't core loss directly proportional to the square of frequency so by the formula of eddy current loss, as frequency is less than rated frequency, should'nt core loss decrease
koi iske notes dena
Please correct the Q at 17:54
Isn't core loss directly proportional to the square of frequency so by the formula of eddy current loss, as frequency is less than rated frequency, should'nt core loss decrease
Last graph me stable point galat he guru ji torque is on x axis
Both point r unstable ...I think
What about u Manish
Q point stable hoga kyoki speed reduce kiye hai
Thank you sir jii 😁😇
Tl will be less than Tm in the question
