Magnet Orientation on an old Len'sRC motor
Teaching the Wee Man how to fly, long story short my old GWS Pico Moth ended up in a tree and I am guessing the throttle was open for awhile and heated up the motor resulting in about half of the magnets in the bell coming unglued. I switched out the bell with a known good one and the motors runs fine so the windings seem to be in good shape but I would like to re-glue in all the magnets so I can get the other motor running again.
Are there any good pages that show how the magnets should be orientated?
Alternating N-S-N-S- ...
However, could be that magnets got to hot and weakened because of this. Weake magnets means higher Kv. Motorcurrent is proportional to Kv (and voltage squared) so don't forget to check/measure your current.
Use thick CA glue, and clothespins to clamp the magnets in place.
