I have just aquired two 2 hp permanent magnet motors, one a Emerson, The other a Baldor. The problem with both is that the magents have lost strenght. The comutator is fine, new brushes installed.The question I ask is can I remove the existing magnets, And add(by cuting the outside case asemblly) Long bar magnets to increase the number of poles from two to four. This is out side my area of knowledge. So I hope someone with more knowledge Than mine can give me some direction on this matter. I also already have a four blade PVC, 7 ft blade assyembly ready to go if I could make it work with either of these motors.
Thanks
