@@mpirron1 P? Is this your answer to one of my questions or to all of them ?

1 : 6 comparison 2 volt rotor, 12 volt stator, I know it since i read comment from other youtube channel.

Did it work? Was it successful?

@@minhle8828 i never got around to it. its been so long i dont even remember i never got around to it.

INTP boys and girls. The 10 yr old taking stuff apart to see how it works. Tomorrow s engineers and technicians scientists

I am watching a different video. The video I am watching is a guy making a video on something he has never done and knows nothing about.

It's not brushless since he put the brushes back in.

But brushes don’t interrupt the current into rotating coils as in normal brushed motor. There is only one pole and rotor coils work like a permanent magnet.

@@KUBA64official take the brushes out. Would it work?

@@wifie9321 The brushes only provide current to the rotor to operate the electromagnet, since it doesn't have permament magnets. Only a small current passes through the brushes, and the main motor current does not. The rest of it operates the exact same way as a brushless DC motor.

@@davelowets but it has brushes to provide power. Without them it cannot work unless you replace parts. Until the magnet is replaced to eliminate this problem, it is a brushed DC motor.

I had a feeling it was like the SepEx field golf kart motors, they have another field to power too & It acts the same way. Tnx 4 sharing 😊

Yes I learned it, I appreciate it

Until you exceed a voltage the insulation on the windings can withstand, arc through the insulation & create a short circuit... or overheat the windings, melting the insulation and creating a short circuit. Given that the armature shaft is steel, it's gonna produce a whole bunch of eddy currents. Eddy currents produce a great deal of heat. Think of a large air core inductor with a piece of steel passed inside while it's energized. While I don't doubt that an automotive alternator can be over amped/over voltage, there are limitations to doing so... for our own safety. The wire gauge of the windings would be a quick way to get an approximate safe maximum input/output. The more voltage used, the greater chance of arcing. The more amperage used, the greater chance of overheating.

@@kaisersose5549 … or overspeed the bearings, or overload them or the windings with too much load. Typically, a motor will stall first in the latter condition, but an alternator may be more lightly built than a typical motor. The original wattage rating of the alternator should be a good indication of the motor's limits.

nothing in english ?

Let me know how it works

I would like to know if it works as well and if at 36volts does it produce enough torque to pull a person because my bike is currently 65pounds with a single hub motor on it I want to make a awd with the rear driven by alternator motor on either chain or possibly belt driven like the surons segways ect

A guy has already done that FYI - but there may be others - but it's not possible to view every YT channels and contents thereof - and you probably just missed it but I'm interested in Alternator conversions for the reasons I've covered in my comment above to the host of this Channel - so I've simply selected this one [the only one I viewed ] for you - to show the possible pitfalls and/or success of the project - which seems quite do-able nevertheless. A link to that vid - From my You Tube viewing history: Bicycle Conversion using a 10,000 Watt Car Alternator 1,085,836 views Oct 15, 2021 "In this DIY project video we are going to convert our bicycle into an electric one. We are going to use a car alternnator that we have converted to a permanent magnnet brushless motor that we have converted in previous project video.

I was exited until i saw the brushes go back in

@@dave95377 me too, can I ask for a refund of my 15min?

Yes, indeed! Also you refer to " Delta and Star connected resistors"; They are the stator WINDINGS.

oh good its nor me alone wondering how brushless needs brushes ..none i own have any brushes

@@dave95377 so your missing the point of the brushes, they are pretending to be the permanent magnets.. if the winding is a reverse stator, you need the center piece to act like the permanent magnet, so you add a DC voltage to the center piece and it here a magnetic field so the electro magnetic field from the three ac wires have a magnetic field to push against.. you could always the center shaft out and replace it with permanent magnets... But don't have a clue how to accomplish that feat of manufacturing in as short a time as adding DC power to it instead.. it's actually kind of genius, cuz making that center piece into day a 4 pole permanent magnet in my garage would be impossible, especially if I wanted to spin that up to 2000 rpms. The DC brushes are a excellent substitute.

Woah, this comment in itself was like an informative video! :D Tnx for sharing! 😊

The vehicle alternator is a very special design of generator in that the field and armature (rotor) are REVERSED so the rotor/armature is now the field and the fixed outer coil now functions as the armature. This unique rotor is known the alternator-claw design, aka bear-claw and supplies much higher current to the battery and at a lower RPM.

and it could actually be converted to brushless...just put some magnets on the rotor

Also rotor is the part that turns not the other way around

36v or 48v would work!

any esc voltage from 24V to 72V on the stator would work (if you use 4-12V on the rotor brushes), just need to cool the alternator or use pipes/something to guide air to the alternator depending on the voltage

WRONG! Lol. I'm just kidding. You're dead on.

"Semi-brushless"... 🤷🏻 Still works exactly the same as a brushless motor, it just has an electromagnet instead of a permanent magnet.

3 phase induction motor

@@VulcaNtGoF A 3-phase induction motor works completely differently

I think it's technically it's a bldc with electromagnetic rotor. And if you have a way of replacing the rotor with permanent magnets.. is love to hear about that... Maybe you have a better way of adding power to the rotor to give it a electromagnetic charge? The stator needs a field to push upon our is but going to spin..

You choose it based on the voltage of the speed controller. If your speed controller is 36v then that's the battery that you need

Speed will match the AC output of the ESC. Speed is limited by back EMF from the stator. It cannot exceed power supply voltage. Delta tends to have lower voltage than Wye but greater torque. Lowering brush voltage will weaken the field and allow greater RPM but with less torque.

alternators are rated in OutPut AMPS. In the automotive application, they are more a current source. While a car is running the out put voltage from the alternator will climb above the 12v of the battery. Usually 13 to 14 volts, This insures that current loads like fan motor defrost strips etc are all supplied from the alternator, not the battery

He ran it on 12.6 volts. Not 48. Wise up.

@@davelowets watch the whole video

you can tell the difference between wye and delta without taking it apart. delta will have 2 or 4 wire ends at each 3 points. Wye will only have 1.

@@mannys8259 not necessarily true, in most common 3 phase application, you will have 6 leads coming out of the motor/ generator. also there are motors with 9 or 12 leads which makes it harder to just tell by simply visually looking for one or two wires.

A motor connected in a Delta configuration will draw more amps than if it were connected in a Y configuration due to the fact that the Y configuration places the windings in series - adding the coil resistance values.

Most of those are 24V, probably higher current too.

It a standard alternator from an older small car. Scrapyards sell them for $10 to $20, in better condition than this one.

Some are 24 volt systems.. Watch out

you can't

Probably a Wye connected alternator hooked up to a Delta controller.

If you make a pulley system and connected that to a grinder wheel, you could easily make a bench top grinder, I would think.

I’m a complete novice. Is there anyway I can post a picture of it?

If you can send me your email we can talk about it

And yes, reverse is made by the 3 phase controller
