cd rom problems

[angus]

i have a small cdrom motor in a foam 3d plane, with a phonix 10 esc. the problem is that the motor gitters or cuts out during increses of throtle. i have programed the esc for every type of start possible, hardest seeming the best, but i cant get it to opperate smoothly? please help?

Could you give us a bit to work with? prop? #turns? #poles stator diameter? etc.

ya, sorry. ive ran a 8x4.3, 7x6 prop from gws(direct drive)
its a 17 turn motor from lens rc

Neither prop is too large enough to cause the problem. I'd try contacting Lens rc and see what they have to say.

This could be one of two things.

Your rotor is not rotating freely and is catching stator or wire, or it is being loaded down by a bad bearing or a spot of glue on the bearings. If your using the stock shaft assembly try some wd40 in there to get it going but be careful with overspray. If a magnet is catching there is not much you can do to fix that. You could break out the dremel with a sanding belt you know that little round sand paper belt. Take the dremel to the stator teeth. And go by each tooth carefully, I have done this, I don't reccomend it if you having problems controlling a dremel :? . But just becareful when you make each pass to not grind up any of the wire, blow all of the debris out and try it. (Please try to avoid grinding the stator, it's a last resort technique, I had a gbx the I recently took apart the stator was ground in the stator rusted.)

The other thing could be bad solder joints due to bad wire or poorly stripped wire. What I do is break out some sand paper like 60 grit. and mask off about 3/4 of wire and start stripping it that way. Just fold a small square over and pull the sand paper over the wire. Check all of your connections. A bad solder connection will almost feel like its hitting something when you throttle up. I was working a custom gbx motor for my friend to borrow and we had this problem so I chopped the bad leads started fresh and voila!

What kind of wind pattern arre you using. If its wye make sure your end leads are stripped and soldered together also.

Good luck with your fix and may your motors never over amp.
