In series motor it is said that with load connected, there is increase in armature current which increases flux. Increase in flux causes increase in induced torque. Increase in induced torque causes DECREASE IN SPEED. I cannot understand why the speed decreases when toque (twisting force) increases. Can you please explain?
I think I have explained the concept of loads in a particular lecture..remember there are multiple torques at play here..one is the load torgue which has a tendency to decelerate the motor and the induced torque which the motor produces. When the Ind torque equals load torque the motor rotates at a steady state speed...Now when you load the motor the motor decelerates and motor speed comes down, bcz the load torque is greater than Ind torque....now due to the drop in speed current would increase and Ind torque would increase till it reaches value of load torque.. and at this condition the motor is again in steady state at a lower speed..thank you...
Hello Sir, i got a doubt here at 9:52, while substituting the value of armature current Ia on flux, Fi, you have cancelled torque induced on the numerator to the torque induced in the denominator, but Sir, the denominator one is actually the torque induced in series while on the numerator, it is the general torque induced term and not the torque induced term in series, but Sir, here you cancelled both but they are not the same torque term, one is torque induced in series term and other is a simple torque induced, so will there be a problem here, Sir??
Damn underrated
u r good i love u
helped alot
Great explanation sir
Excellent sir.
nice explanation
Sir in formula of torque induced, what is "K" and "C" stands for? And what are there units and values?

Pls explain the concept of load torque and why it decelearte
Suppose I use inductive load how it decelearte my motor.. at what point induced torque equal to load torque sir
Sir I didn’t understand why induced torque can't be zero in a dc series motor.
what is the Lf?

Since the motor is series motor induced torque will be of series only
Sir, please use an external mic or something. Your voice is not that much audible. Thank you.
+Naresh Ch. i am already using one..Lemme see what's the issue once I come back from my vacation....Thanks for noticing...
Notice me sirr pleaseee
Sir Hindi
Sorry, I am not able to squeeze in the time, I will definitely try to upload a few videos...
