So I started working in a windows application. But i started having issues with blocking the event loop when using while loops that i never encountered before when using while loops in console application. My theory is that I used commands like getch or cin to exit the loop in the window...

So I've just recently learned what a event loop is and the concept of blocking it. My question is I've written loops before in a console (main()) program and this never happened. Is there something about a GUI program (WinMain()) that makes loops block the event loop? Also I understand that...

So for this question, I understand the math but just wanted to be clear on a few things. So I had this question on my midterm but instead of tensile and compressive stresses, it was tensile and tensile stress. I initially thought that the delta sigma in the integral was the maximum stress so in...

Ok so the rate 20 HP represents Pout correct? Also in a ideal motor both rotational and armature loss are zero, but what about field loss? thanks

Hello, so for this question I know how to solve it but I still have a few questions. First when the question means it's rated at 20 HP and 600 V, it's referring to the source voltage and Pin correct? Also in order to solve this question, the rotation loss Prot was neglected. This was because at...

Also when you mean internal losses, you mean specifically rotational losses. Armature and field loss are still present in the ideal motor case where back emf = Vsupplied

I think i understand, so when back EMF = V, this speed is the ideal where losses are ignored and the no shaft speed is when when losses aren't ignored anymore

My textbook is very confusing because it refers to the case where EMF = V as no load speed but it also refers to no shaft as no load speed

Is it correct to say that when EMF = Vsupplied and hence not armature current that this is the max rotor speed, and that when there is no shaft and armature is non zero then this is the no load speed which is slightly less then max moto speed.

Ok after looking over my notes, I believe that there's more than one condition for no load (Tout = 0), one condition is if Emf = Vapplied and hence armature current (Ia) will be zero. But I'm pretty sure that there is a no load condition where Ia isn't zero and there is power delivered to the...

Oh so these are the conditions under no load in DC and induction motor correct?

TL;DR Summary: So I'm just confused when the question asks me to solve for the no load speed of DC motors and induction motors. Does no load condition mean that the output torque (Tout) is zero? This is what I was assuming so far for both DC and induction motor. Is no load condition the same...

Also in picture 2 in the instruction sequence. Is it in the last instruction in the sequence, instruction 7 where it says BNEQZ loop, is that where the address of the loop state is set. So in this case the address of the loop state is the adder state so instruction 7 BNEQZ loop means it's...

Ok first off thank you for not insulting me. And yes I think got it now, so it will keep getting stuck in the loop until RC is decremented to zero. So if RC isn't zero it will return to the adder state, so in that state It should add X to X during the first loop, then after RC will decrement by...

Nope, still trying to figure it out
