Hi Gordo, I used "black iron pipe" for my first motor's flux ring...that's some nasty stuff to machine! My little Sherline lathe likes a 1020 mild steel...
Hi Ricarde and all, ... No. For 12 magnets it's ABCABCABC as you already know after building 35 motors. According to Ludwig Retzbach's "Brushless Fibel"...

Hi Bandgurumore (?) and all, ... Should be between 0.3 and 0.5 mm ... Replace with 12 Neodymium magnets. Met vriendelijke groet ;-) Ron van Sommeren near...
Hello, I've been following this group for quit some time now an now I think it's time for me to post a question. The questions I have doesn't involve BL motors...
hi,
Ron, do you mean like this : ->/CurrieMotor/-> 9_14_ACaBAbCBc

Hi Ricarde and all,

Hi,
If we look the concetrated windings motors
number of teeths does not give RPM - magnet poles does.
:
3 tooths 2 pole motor ratio 1:1
6 tooths 2 pole motor...
... Hang on a bit on this, I'm looking to develop full motor formulas but probably will be around mid week before I get to it. Should be able to solve out and...
... remember the more number of teeth and number of magnets is apart the lower is the coverage. you can build a motor with 3 teeth and 100 magnet poles, the...
I assume you have seen one of the thousand links to the "solar powered vehicle with in-wheel motor"? It may be hard to find a stator with so many teeth, if you...
Look at post #3837. You need a lathe and a BIG hammer!!!. Its a little brute but it worked for me. Greetings to all in the group. ... hard drive's case on my...
Hi Wolfgang, Yes, you can build an inrunner from it, stator sheets are a bit thickish at 0.5mm. Pictures? Build it as an lrk with 10 or 14 magnets or as a...
Hi Gordo and all, ... Others have already answered this question ... Only the length of the fluxring(magnetcarrier) and the statorcarier varies with the...
I was able to glue the 5.5.1 magnets right on to the original ring magnet. It helped with spacing and polarity. I was able to get the prop to spin and then...
... I don't think that's feasible, unless you match the magnet size and polarity from the ring magnet, you can end up with some strange magnetic fields. ...
Its not heating up though, and I guess the ring magnets may be slightly larger than the squares but the polarities match. The thing is that it did run then...
... startup. ... With or w/o a prop? Could be ESC timing related. ... I just grind the end of the teeth to clear the magnets. Doesn't need to be balanced since...
... In theory yes, but it depends if the bell is perfectly round, and if the magnets are sitting flush to it. I just mark the stator ends and magnets with a...
Has anyone heaqrd of converting auto alternators to brushless (using magnets in rotor), or in as-is configuration using exciter winding? This presumably...

hi,
Yes, I built one. Do not know from what car it was. I
used just only the 18 tooth stator where was
concentrated windings from 1.75mm wire wound in same...

Hi All, I saw in a recent post that a 10-magnet rotor will work with a standard LRK winding pattern, producing higher speed with less torque. I have 12-tooth...
I have exactly the same problem with a new Pheonix 10. The motor started fine and ran with great power ( strong magnets 5x5x1. It ran almost cold to the touch...
You don't have the magnet on magnet setup though do you? I got the bell down farther over the magnets and that helped a great deal but it still has trouble...
Hi all, http://wwww.supermagnete.ch now has N50 magnets in stock, 5x5x1.2 mm, gold plated. Met vriendelijke groet ;-) Ron van Sommeren near Nijmegen, the...
