[QUOTE="ciaonzo, post: 6444752, member: 607015"] So at this point, you might think that a 3HP equals a 35mm top plate or that it has three .75" slugs or a total of 2.25" of magnet height. You might also think that a TC-9 equals a 12mm top plate or that it has two 1" slugs or 2" of magnet height. The problem with that logic is that the motor for an LMS 4000 is called a 3HP+ (the plus sign presumably meaning that an extra slug was added) which might suggest that it has a 35mm top plate but it has a 12mm top plate as seen in these photos, sitting next to the 3HP. I've left the threaded ring on but it is not part of the flux circuit (though, it does play a part in reducing flux modulation). Only the 12mm thickness is carrying flux. Also, notice how the T-yoke is cut down to maintain the traditional relationship of a TC-9 top plate and T-yoke. Clearly that specific flux pattern is a strict requirement and resembles a TC-9 more than it does a 3HP, yet it's called a 3HP+. You can also see the copper shorting ring beneath the top plate.
