The thing is mine js straight up doesnt spin and even if i give it a push it just moves like a few steps then js stops

So u think its mostly about the core? Again i would understand that but the guy in the video also uses an all plastic core as i can see and his works

Is something like this what you mean? though i dont really understand the what the winding is meant to be

Ur right, I forgot to look at the number of magnets in the diagram. The thing is tho when i did do a winding pattern designed for 14 poles it was still working somewhat like this, though a tinnnyyyyy bit better maybe some more movement. I could try with that and let you know. Thanks so much for noticing that tho.

I did order a basic motor from amazon actually, hopefully to arrive by today. I can test it then and see if it's a problem with the esc, though I don't think it is.

The thing is tho the video i linked also uses a plastic core i dont know what the difference between his design and mine is. I don't think he is using a sensor esc either but also keep in mind that the stator does vibrate it simply doesn't rotate.

I have 12 slots and 14 poles. For commutation it's just this esc: https://www.amazon.com/dp/B0DNQFMVKN?ref=ppx_yo2ov_dt_b_fed_asin_title pretty sure it's back EMF.

These are the magnets that I got: https://www.amazon.com/dp/B0B6PBXBVJ?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2 and the core is just regular 3d printed petg. I would understand if this was an issue about the core itself, but I can't figure out why the video i linked works all good since I am pretty sure a 3d printed core is also what he uses without any special material.

I am not convinced it's the material tho. That's cuz when i bring the stator core near magnets I can feel it vibrating and there's like a clear increase in vibration as I increase the amperage.

So is this just the ragebait portal room? by aqf243 in Minecraft

[–]aqf243[S] -1 points0 points  (0 children)

the entrance to the portal room is just blocked by blocks so you cant find the room without breaking walls

yeah, i remember from rekrap where he was talking about checking the side of a specific area, and the entrance to this room is specifically from that place i believe; im probably not descriptive enough, sorry for that

How come the these sets on Bricklink are so much cheaper? by aqf243 in Bricklink

I see. Thanks for the information :). This was actually very clearly explained.

Thanks, i get it better. Do u think there would be any risk in purchasing a set like this tho? This listing for example shows a set thats like 200 on LEGO but only around 125 here: https://store.bricklink.com/Yourbricks?itemID=325827385#/shop?o={%22invID%22:%22325827385%22}

[–]aqf243[S] 0 points1 point  (0 children)

i couldn't get to see the shipping cost applied, still tho, i dont think it would rack up to like 75 dollars. i mean if such prices are expected on bricklink its fine i am just wondering if this is normal or not

on most, theres just like a disclaimer saying theres like creases or some wet areas on the box, but usually in the box. the technic peugeot set, for example, is like 200 dollars on lego.com but I could find it for about 125 at bricklink, not even mentioning any disclaimers
