How the Stator and Rotor work in a motorcycle

[@xhuliospeed]

Seriously one of the best videos out there for rotor/stator and 2/3 phase alternator!

[@twillsJKZ]

Thanks so much for posting this. I’m a visual learner and this helped tremendously. I believe my stator/ reg/ rec has gone on my bike, so instead of just changing things I have no idea about, I now have a better understanding of that they actually do. Will help with troubleshooting. Cheers!

Never know why I landed on this video. That explaination❤️ , the way u connected it to bike battery example I VL never forget the concept champ!, Keep teaching

[@TheMotorcycleMuse]

Great to hear!

[@JoNNy8904]

Thank you so much for taking the time to do this! You're an awesome teacher.

[@paulbraverman1432]

Watched this whole thing and now have a perfect understanding of the stator. Thanks!

[@ahmedelzohry4101]

god bless you , thank you for doing this huge effort and sharing your knowledge to all people

[@balajiraju2232]

The best video for understanding alternator... Thanks for the video

[@marcelluswhyte9015]

Excellent ! Easy to understand video . Keep up the good work ! 😁

Brilliant video. I've been unsuccessfully looking for a MC mechanic to replace my old points ignition on the 1972 Yamaha. So I have to do it myself. I've got the replacement CDI components. Now I need to figure out how to wire for lights and ignition switch. Another decision wire it for a battery or no battery.

[@jimmyghersi]

Great explanation, I finally understand it

[@Usmanthemecano]

That looks like AC ripples on a lab scope. This is cool

[@ALb3RtO1010]

Great explanation and video. Thank you.

[@yarilich544]

A bit too slow for my taste, but now I have a basic understanding how motorcycle battery charging system works. I came, however, to confirm if generator rotor also doubles as a crank flywheel in motorcycles

[@christiankirbyapostol9704]

Good information thanks

[@josephjenkins2270]

Where did you get that stator from? It looks like the one I need.

[@noelpichay9229]

very well explained love it dude!..

[@mrpeter9758]

Hi. What's the different between dry alternators like on cars and wet like on the motorcycles runs in oil? I meant what's the function of the oil and why that solution commonly used on motorcycle? Thanks!

[@chrisvondetten7650]

Could I share a video with you? I really need a second opinion to help me diagnose a sound.

[@Carlos-bp1vp]

I have a question: I have an XR650R with a two-phase stator. It comes with 12 poles - 2 are for ignition (I did not touch these), and the other 10 are for lighting. I re-wound the 10 poles with 16ga magnet wire, alternating direction and doing about 34 turns per pole. I left some magnet wire hanging off pole 1, and also at the end on pole 10. The magnet wire from pole 1 and 10 were soldered to 2 individual wires (I think similar to your 2 yellow wires). My problem is when the bike is running, I put a multimeter on AC with one end on either one of the 2 output lighting wires and the other end on the frame and I only get around 3v - does not matter which wire I test. This is all just open circuit before the regulator. I tested for continuity from both lighting wires to any point on the stator body to see if there are any short circuits and it was fine. I also checked resistance by connecting to the two lighting wires and it was 0.5 ohms. Not sure where I went wrong, any ideas? It's supposed to give 200+ watts.

[@jackster97]

Good video but please say stator correctly lol had me laughing everytime you said it

[@dilipraj-sy6bp]

Hi.. I have few questions. please answer if you know it. 1. The insulation of the coils will diminish due to time, heat and water fall on stator cover? 2. After long term usage will the stator undergoes short circuit due to wet or cold air and due to water spray on stator cover?

[@bfnew4440]

Great vid!

[@armandoquezada5559]

Lots of good info. So the stator also has to do with spark and firing order correct? My bike won't start unless I bump start it but runs good. Would it still be the stator?

[@chriscs9080]

Hi there .. thanks for the video.Today I replaced my timing chain and found out that in two coils of the stator two of the windings at the bottom are black , the rest of the windings look fine ( for example one coil may have 18 windings looking from the top and two of them are black ) . I dont have any issues with the bike and battery is charging fine at ~14.7V . Can a stator work fine when it has black windings or I should replace it?? Thanks!!

[@dwayner2518]

Well explained video. Thank you. Disregarding the pickup timing, given that the stator produces AC current the direction of the rotor doesn't matter then, is that correct.

[@TheMotorcycleMuse]

I don't think direction would matter but it would probably affect engine timing as the rotor interacts with the pickup coil

[@dwayner2518]

@@TheMotorcycleMuse yes no doubt it would. I am retro fitting an AC charging system to an old WW2 motorcycle as the old DC generator has failed and parts are impossible to get, so I thought it was a good time to ditch the old 6V + ground system and upgrade it to 12V - ground as these parts are so common today. However the Rotor I am using will be turning in the opposite direction and I am not sure if that will affect the AC output for the charge cycle but being AC I don't think it will. The pickup is not an issue as I will be repositioning the pulse/pickup and using a custom reluctor. Anyway thanks for your time.

[@saadshahab1403]

Why can't we use a bridge rectifier with LC filter to get pure dc instead of increasing the phases?

[@TheMotorcycleMuse]

They do use bridge rectifier type electronics in motorcycle regulator rectifiers and possibly other more advanced methods to smooth the output. The more phases output from your alternator the better but the more phases increases the complexity and electronics and hardware and costs. A three phase alternator is generally considered the optimal output but you will find smaller cc motorcycles with two phases as they might not need as much power output.

[@dharmakissoon]

How can I put this on my ninja ebike

[@christiandejesus8789]

This is a stator and flywheel a rotor is a completely different part on the other side of the engine

[@មឿងភក្ត្រា-ភ6គ]

If stator smaller than rotor about 3 to 5inch Does it work or it's provide the power? Does it have the problem if I take it like this?

[@មឿងភក្ត្រា-ភ6គ]

My old stator broken So I can't buy new one. But I have one that smaller than rotor 3inch.
