How RPM and number of poles affect frequency

[@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

[@mr.lonen-ff9893]

super simple but adequately informative. thanks a bunch!

[@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?

[@dakshyani5912]

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

[@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.

[@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?

[@dmitrytsibyakov2597]

Thank you! Easy, understandable. Without many words!

[@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

[@hus390]

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

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

[@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.

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

[@menombakglobalis]

depend on phase,, single phase same number of stator & rotor pole... More phase will different number of stator & rotor pole...

[@gamelover2594]

the number of stator poles also affect the frequency?

[@dineshj1998]

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

[@mr.dattakolte9395]

Superb sir... superb teaching methods...

[@grupinfractionalorganizatp5003]

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

[@rs45888]

Well explained!

[@shreeanand6812]

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

[@saeadabdoli]

Nice explanation,thanks

[@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

[@zainahmed3140]

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

[@james77011]

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

[@LAFAMA5759]

Well Done!

[@Dc_tech386]

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

[@eytonarenas2131]

Where is 120 came from?

[@chrisdowland]

Awesome viedo

[@premanandbrined9379]

How to calculate rpm to poles

[@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

[@venishraja4888]

No

[@aligarmabi2912]

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