RE: (ET) General discussion of motors

["Elie, Larry (L.D.)" <lelie ford com>]

I don't have all the answers in front of me.  But question 1, 'Large Frame'
describes the frame itself.  
ALL the 'Large Frame' tractors have very similar mechanicals; transmission,
dimensions, etc. (except the 
E12M...), but the motors and controls are quite different.

Subject: (ET) General discussion of motors


        Hi
        I am hoping to start a bit of a thread here and I hope that the
discussion is informative both from a historic and technical perspective.
The questions are.
1.)     When GE refers to large and small frame tractors are they talking
about the motors as in large frame and small frame or the steel backbone of
the tractor.
2.)     What type of motors are in each of the models and the accessories
and who manufactured them
                                -Large frame?
-       permanent magnet
-       Shunt wound 
3.)     The E12's GE seem to have used a large frame motor, while in the
B145 Wheelhorse seems to have used a small frame is this correct? 
4.)     Clearly the big motors in the tractors, blowers and cultivators are
GE are the motors in the mower decks and small frame tractor GE as well?
