Hey Man appreciate your work. Could you please help me understand what voltage is provided to rotor when nrotor=1800 and nstator=1800 (time 13:16 ). If i understood corectly when nelectromagnet is 0 rpm, voltage frequancy in rotor is also 0, which means that there is a Dc voltage or there is no voltage at all, second situation obviously does not make sense becouse there wouldnt be magnetic field, first situation is also not clear becouse how would you provide dc through AC/AC converter. I have also second question if i am right the current is provided to the rotor from the grid(but is it only during excitement or also during normal work?), if the rotor is provided with power from the grid whole time how is it possible that the power in wires is going in 2 opposite directions at the same time power going to the rotor and power going from the stator(is it possible becouse of 3 phase ac voltage?) or is it working like that: after generator is excited stator provide power to the grid and to the stator?
@bigbadtech 12 күн бұрын
first question, 0 Hz = DC, the middle part of AC to AC converter is DC so it's just AC to DC second question, yes it's 3 phase AC sometimes it goes in some times it goes out

Hey Jim, for the final problem, if I am trying to calculate S2 using I^2 * Z, do I keep the absolute phase shift for current since we are dealing with impedance in the equation and not voltage?

Sload= 61.57 angle -114° at 7:49
@bigbadtech 18 күн бұрын
Remember AC power is always calculated using "relative" phase shift. kzbin.info/www/bejne/pKTIY6mJobSig6csi=70pdqlKKBlYBHfN0&t=2237 In this example current leads voltage by 52 degrees thus apparent power has an angle of -52 and can be resolved into + real and - reactive. An incorrect angle of -114 would have - real. Negative real power is an active source like a generator.

@@bigbadtech Okay I get it, so E is the reference that's why both Iload and Vload has a negative angle. thanks

Is there any great reason for using octal bases on relays? Not as intuitive when visually inspecting circuits.
@bigbadtech 18 күн бұрын
If it was easy to be an electro-mechanical technician you wouldn't earn the big money. Yes, the pin outs for an octal base are a little odd but once you get used to them it becomes more intuitive. There are control relays that make use of isolated single pole single throw switches (SPST) rather than octal base relays (which use 2 pairs of SPDT transfer contacts) but, probably because of historical inertia the octal bases are more frequently employed.

Thank you Jim for your videos. I really wish you would have gone into a little more depth on the explanation on real and reactive power supplied to the grid. I know you say you studied it so we dont have to, but im studying it too and find it difficult to understand the relationship between how real power and reactive power and how it is independent from eachother.

You weren't overstating it in the thumbnail text; this IS the best lecture on the subject!! Very much looking forward to your transmission line lectures, you really tickled me at the end with what's to come :) Thank you very much once again for the work you put in. One more thing which won't make you happy: in Belgium we call it a star (ster) too. Even better, the delta is called a triangle (driehoek) :p

I am trying to convert my drone's motor bought from DJI from delta configuration to y configuration to make it spin a quieter propeller at a slower speed and found your video very good for the basic concepts. But the drone motor has 14 magnets in 7 repelling pairs, and the 12 windings make counter polar forces in 6 pairs. I am failing my attempt. I used to rewind the entire motor myself that worked well. So, I maybe that is what I will do next.

Good series. I have always been annoyed that all the motors and transformers I have ever looked at have never had the dots marked.
@bigbadtech Ай бұрын
My personal annoyance is the seemingly random orientation of displacement diagrams. Some manufacturers orient 0 straight up (as presented in this lecture series). Some manufacturers lay them on their side ... but not like a phasor diagram with 0 on the right hand side! They lay them so the delta is tipped so the reference voltage to virtual neutral dangles off the left hand side! This being said you should be able to compare the HV and LV displacement diagrams regardless of chosen orientation to determine the resultant leading or lagging phase shift.
