permanent magnet in DC Motor
(OP)
Hello all,
I'm restoring a old dc motor from a wheelchair, I'had to re-glue permanent magnet because it was un-sealed probably caused by overheat or oldness.
but I'm not sure that the sens and order was respected when I reguled it...
Is permanent magnet have sens ?
TRhanks a lot

If you have magnets from several motors, you will have to match a North outside with a South outside.

I'm able to identify magnet polarity with another toy magnet and have found two identical pair of magnets.
Now I want to re-glue them together to the case, but a doubt arises...
when I couple 2 same magnets, I have a relatively strong force that repulse the two magnet...
It is normal ?
Thanks a lot

The two magnets that are not shown in the picture should be the opposite polarity.
That is unless the armature is somehow non-standard.
