The problem with taking apart motors with permanents magnets is not as much the loss of magnetism but its force. I have disassembled quite a lot of motors with perms. Back in 'the old days' when I was still young ;-) I already realized that it pays to recycle and removing the copper made nice pocket money.
Problem is that as soon as you remove one of the covers the rotor most of the times does not stay in the center - it immediately bonds to any other metal it may find, damaging the magnetic material or even permanently attaching it to this metal. But the motors I handled were strong - strong in the sense that you should not wear a mechanical watch when handling the motors ... I've had quite some motors where I had real problems removing the rotor from the housing after it got stuck to the metal core of the coils. So if you like to keep your brushless or stepper motors in qorking condition it is best not to disassemble. Rob -- Error! Grasshopper is disassemble.
