It appears you can do it with Emerson. I took a rotor out of what appears to be an unmolested Emerson 16" 24648 big motor stump to see what type number was stamped on the rotor. Type number 17666 for a 12" 6 pole stationary was the number stamped on it.   It appears you can rob Peter to pay Paul with Emerson rotors.

wonder if there is a difference in the amp draw with the 17666 rotor running in a 17666 stator as oppposed to running in a 24648 stator ?

Same number of bars in each?

I have a few more big motor stumps I could look into down the road. What are the chances someone swapped the rotor out in the 24648 I took the 17666 rotor out of??  I would bet rather small.  :D

Dr. TOM NEWCITY of the EMERSON REASEARCH FACILITY in ARKANSAW and I discussed this briefly once upon a time. Neither of us could validate for sure at that time. This became an obsession today, and I had to know despite sweating a few bucket loads in the warm storage facility. These are the results of 4 Emerson 16" big motor 4 pole stumps I have in my stash.



24648 16" 4 pole Big motor:  17666 type# stamped rotor


27648 16" 4 pole big motor:  19666 type# stamped rotor


#2 27648 16" 4 pole big motor:  19666 type# stamped rotor 



Early long tag 21648 16" 4 pole big motor:  17666 type# stamped rotor.

With 4 big motor 4 pole Emerson ducks in a row with 12" 6 pole big motor rotors in them, I didn't count the bars.  :D

There would not be a point. I only ask because both the GE and Westy tank 6 wingers have more bars in the rotor than their 4 wing counterparts. Its been determined here in the past, at least in the GE's, that a 4 pole rotor produces odd effects when used in conjunction with a 6 pole stator and vice-versa.

Thank you for the information.
