This video will help you to understand;
1. How the speed of the dc motor affects its torque generation capability.
2. Why DC series motor should never be operated at no load.
3. How the curves of compound motors differ from shunt motors.

Sir ur videos are very knowledgeable i really like them, sir it's a humble request to you to make videos on induction motor and it's characteristics plsee sir 😊😊😊

@techinsight1418 3 года назад

1 phase induction motor is running in special purpose machine series

@techinsight1418 3 года назад

3phase induction will start after synchronous machine

Nice explanation

Sir At no load in dc motor, how can we take Ia is zero ?? Please 🙏🏻

@techinsight1418 Год назад

Ideally, at no load we don't need torque (as there is no load) so for zero torque, armature current is zero( as T directly proportional to armature current)

at 7:22, how can we write k^2 since k is different for torque and backward emf from the formula, the K for torque will be = PZ/2*pi whereas k for back emf = PZ/60.

@1growth733 3 года назад

Yes, K is same.. if we take angular speed. Since both are constant....... It doesn't make much difference...Therefore for N you can write KK' instead of K^2

@DosPerspectiva 3 года назад

@@1growth733 is it appropriate to say k approximately equal to k'?

@techinsight1418 3 года назад

No k and k'are not equal.... But both are constant and thus, doesn't affect the speed torque curve
