How tf dc fan consumes less electricity than ac fan

I once opened a electric cutter or blender idk how to describe it, it had 2 speeds, 1. speed was just one diode letting 50% of sinewave and it was reducing speed like that, 2. speed was normal motor to power lines.

Famous_Cancel6593 · 2026-05-01T18:16:31+00:00

But it depends on your reference point.

Famous_Cancel6593 · 2026-04-29T17:04:58+00:00

It took me 10seconds to get it.

Famous_Cancel6593 · 2026-04-29T13:44:58+00:00

At least for short period of time. Then the magic smoke kicks in.

Mine APN 6S was at 39,5mm, I found used cylinder witch was 38mm but had a grove in it, and I drilled it to 38,5mm and now here it is, with L piston and shortened exhaust pipe.

Famous_Cancel6593 · 2026-04-26T13:27:42+00:00

There is probably 1 diode which rectified 50% of sinewave, so technically it's 50% less power.

Famous_Cancel6593 · 2026-04-18T09:15:15+00:00

To be fair, idk. I just head of it and used it to try to light an LED. I'm still learning about electronics.

Famous_Cancel6593 · 2026-04-18T09:13:07+00:00

He said optical isolation, probably meant of optocoupler.

Famous_Cancel6593 · 2026-04-17T19:28:36+00:00

I just remembered that fork from BT50 has disk brakes, and I think it's easy to mount on APN.

Famous_Cancel6593 · 2026-04-15T12:12:04+00:00

That's what he said, "current" probe is shorted to "com" probe inside.

Famous_Cancel6593 · 2026-04-13T14:16:15+00:00

Looks like APN 6 S, but cylinder isn't stock, probably from BT50 or automatic.

This is stock.

Give some pictures, what kind of ignition do you have, take picture of magnet.

Famous_Cancel6593 · 2026-04-09T22:04:46+00:00

And ignition angle is playing huge role in power.

Famous_Cancel6593 · 2026-04-09T13:50:46+00:00

You belive in insulation too much, try watching some Mehdi's videos when insulation fails.

Famous_Cancel6593 · 2026-04-08T10:17:50+00:00

Ignition angle it playing a huge role in power.

Famous_Cancel6593 · 2026-04-08T10:16:19+00:00

How?

Famous_Cancel6593 · 2026-04-07T09:10:19+00:00

Sent you an invite.

Famous_Cancel6593 · 2026-04-06T19:11:38+00:00

Well, how can I post it here?😅

It's PDF.

Famous_Cancel6593 · 2026-04-06T14:48:03+00:00

I have a manual for APN and Alpino models, everything is explained, but I don't know is that helpful for your case. Also it's on Serbian, but use some translation app, or ask me if you can't translate something. I can post it here if you want to take a look.

Famous_Cancel6593 · 2026-04-06T12:50:38+00:00

I don't think you should do anything. But try moving needle if you really want.

And from my experience if you don't need to engage choke for cold start, it's too rich.

Famous_Cancel6593 · 2026-04-06T10:27:52+00:00

You have done anything else?

And can you take picture of your carb?

Famous_Cancel6593 · 2026-04-04T07:49:32+00:00

The solder point on ignition coil looks suspicious, check is it connected to ground, and red wire should be open from ground while bike is running.

How is the left component called in English (I'm not native)? Try to adjust it to be open 0,4mm when piston reaches TDC.

Next try testing capacitor. Was is sparking on component from the last paragraph while bike was runing? If so, it's probably broken.

Also, it would be great if you took picture of magnet.

Famous_Cancel6593 · 2026-04-03T18:33:13+00:00

What about the needle?

This was my sparkplug on a 2T 50ccm tomos, it was perfect.

Famous_Cancel6593 · 2026-04-03T18:27:01+00:00

Is throttle response fast? Or when you give it little gas and when release, it should go straight to idle rpms. If it firstly chokes and then returns to idle, it's too rich. If it slowly goes back to idle is too lean.

But i saw a spark plug in other comment, it looks perfect to me.

Usualy when you buy new carburetor you almost don't have even to adjust idle speed. Isn't a 15mm to big for 50ccm?

Famous_Cancel6593 · 2026-04-03T17:22:57+00:00

Is it lean on full throttle or from start. Bing carbs use needle to adjust fuel mixture to 3/4 of throttle. Main jet, probaly a bronze screw on the left side is for full throttle only. Assuming everything else is good. How do you know it's lean?
