How RPM and number of poles affect frequency

Two things affect the frequency of an alternator. The rotational speed the alternator is spinning at and the number of poles the alternator has.

I can't thank you enough! I was having trouble understanding this concept but you made it so clear. thank you sm

[@mr.lonen-ff9893]

super simple but adequately informative. thanks a bunch!

[@hus390]

You are the king of electricity explanation. Thank you very much!!!

[@dmitrytsibyakov2597]

Thank you! Easy, understandable. Without many words!

[@milkcreightronny]

at 2:00 you say "in a full 180 deg mechanical rotation we complete one full sine wave" I think you meant full 360 rotation

[@nickb1875]

Great video sir. But I'm still wondering if an avr can compensate on behalf of rpms when the generator is at moderate load

[@TheTechnicalTraders]

Question on Motor Poles and current need help understanding please!
Given the same motor dimensions, kv, volts, and propeller/wheel how does the number of poles affect the amps/current under load.
one motor has 6 poles, the other motor has 10 poles.
how would the 10 pole perform? smoother rotation? more torque for sure, but would it draw fewer Amps with same load and RPM as it does not need to work as hard?

[@mr.dattakolte9395]

Superb sir... superb teaching methods...

[@james77011]

in the U.S we measure frequency in hertz(hz) instead of cycles per seconds(cps)

[@rs45888]

Well explained!

[@saeadabdoli]

Nice explanation,thanks

[@LAFAMA5759]

Well Done!

[@dineshj1998]

hello sir, Nice video..I have doubt that if we increase the poles, will that affect the amplitude.

[@shreeanand6812]

Thank Sir your video is very much helpful for me👍👍

[@farhaadfarhaad497]

Hi there . I am always having these two questions . In AC circuit it is said that current always keeps changing it's direction . If so , why we always have the same hot wire ( when testing with pen voltage tester) . Second question : Is there really any kind of movement for electrons in a wire when we apply some voltage ? Thank you so much for your help.
I have learned a lot from your videos

[@TheElectricAcademy]

There is actually very little movement, meaning that the electrons don't move completely around the circuit. They just shuffle back and forth, which is what creates the heat.

[@chrisdowland]

Awesome viedo

[@NicholasKandis]

At 01:57, narrator erroneously states 180 degrees creates one cycle.

[@jimklyman9602]

I like the general thought behind this video explanation about producing the electric voltage, but am a bit disappointed with the current representation. The video shows the armature starting in the middle of the Magnet field that has the peak density of magnetic lines of flux, but the voltage (sine wave graph) is shown to start a 0 volts. I do not believe this is correct. As shown, if the armature is actually moving, the maximum voltage will be induced as it is cutting through the maximum density of magnetic flux. Therefore, the depicted sine wave is 90 degrees out of phase. The start of the graph should be shown at the maximum peak voltage and not starting at 0 volts.

[@00savage25]

At 1:56 your referred to 360 degrees as 180 degrees.

[@TheElectricAcademy]

Argh whoops.

[@bill4all782]

@@TheElectricAcademy Is the formula affected for three phase the same?

[@zainahmed3140]

Formula is actually Nsyn=120f/p
Synchronize speed is inversely proportional to the number of poles.

[@adeche6416]

What is the connection between number of stator pole and number of rotor pole, must both be equal in numbers?

[@grupinfractionalorganizatp5003]

please make an example with that formula (P=2 x N =1400 RPM) /120 =23,3?

[@deeznuts-pf2lv]

Shouldn't more poles mean less peak voltage because now north and south poles are directly next to each other so the flux lines bend at the corners and not as much flux passes through the coil?

[@TheInspector369]

Cual es el nombre del libro? What is the name of the book?

[@wingedbull1257]

So which one is better 2 or 4 poles for generator?

[@szekerespista3758]

With 2 pole you need higher speed, with 4 pole the speed can be lower to achive the required frequency

[@gamelover2594]

the number of stator poles also affect the frequency?

[@Dc_tech386]

So 3000 rpm would give 60 hz at 12 pole is that right

[@faizullah3375]

But i can't realise that why speed decreases with the increasing of number of poles?

[@abdulrouflone_5555]

You won't produce a square wave not a sine wave
It should be noted

Where is 120 came from?

[@venishraja4888]

No

your sketch couldnt be right in this situation v is maximum ......
