Rewound cdrom motors

This message from "Steve Corbin" <crash_corbin@earthlink.net> brought to you by EFLIGHT!

I remember that about 40 years ago I bought plastic model kits of destroyers and battleships made by a company called "Paul Lindberg". These had a kit motor that you built yourself. That was the last time I built an electric motor. I'm wondering if I would have any better luck today making my own motor than I recall having when I was 12 years old. Is it difficult to rewind these motors? What kind of tools are required? Most people I know have four fingers and one thumb but I have one finger and four thumbs on each hand, and getting the two hands to co-operate with each other is a real feat. Is there a on-line tutorial, such as "cdrom motor rewinding for dummies"? The cost savings sound attractive but I admit to feeling intimidated. Thanks to all of you on this list, we're all great.

The only hard part about building your own CDRom type motor is winding the
stator. The best tool for this is a length of dowel that will fit snugly
into the center of the stator. This can then be held in a vise, or between
your knees, leaving both hands free to control the wire. This makes it much
easier to not bend the 'tails' of the magnet wire left for making solder
connections while winging the stator. I've found that these tails have a
disturbing tendency to break off just after I finish winding a stator. Thus
requiring me to strip and rewind the stator. www.gobrushless.com can sell
you a motor kit and they have assembly instructions on their site. There
are other kit dealers too.

Winding CD ROM motors can be problemmatic at first. My first two
attempts were a disaster. One had a short, the other had a misswound
phase. Both just wouldn't run. I realized that I had to be much more careful.
I then bought some of the carbon fiber bearing tubes from GpBrushless and
that allowed me to hold the stator securely while winding. I have now wound
two successful motors (22.7 mm, one 17T, one 21T, both 12 pole rotors.

GBL ships a generous amount of wire in their kits. If you need to re-wind,
throw away the unwound wire and wind with fresh wire. What's the saying
about new oats vs. old oats?

This message from bruce johnson <brucej@alphalink.com.au> brought to you by EFLIGHT!

here is a question for the people who know something about
cdrom motors.
do you need a complete controller to make them work ?

what i mean is can they be wired for just on and off operation
or do the coils have to be switched no matter what.
thanks
bruce

basically the controller takes the place of the commutator (sp?)
and brushes. Which do just what you said, it switches the coils on
and off as they pass the north and south magnet poles.

They can be wired for on and off but you'll still need a controller.
For simple on off such as a free flight model or control liner would
use plug into the controller a servo tester. This will take the place
of the transmitter and receiver and allow the motor to run at a set
speed.
