The same is true if their magnets are stronger, as there is more field for the armature to push against.<br /><br />Since some of my motors are weaker motors, I had hoped I might be able to convert them to the 4-pole version simply to double the current input to them, by using two armature windings at a time rather than one, for every commutation-segment-rotation, which would perhaps double their torque (and halve their speed). <br /><br />It's too complex to do, though, for my capabilities and tools. <br /><br />The armature (well, commutator) generally seem to have 16 segments, at least on the PMDC motors I have opened up for maintenance. For some reason I cannot remember what relation the number of segments has to the motor properties, but my day only started about 15 minutes ago, so I'm a little muzzy. ;-)M.E.https://www.blogger.com/profile/15375034485988839284noreply@blogger.comtag:blogger.com,1999:blog-6231841547435511043.post-30816051478799317062009-06-04T09:43:38.498-07:002009-06-04T09:43:38.498-07:00The post took this time. :)
