I mentioned that about a dozen posts back:

The 7090 certainly used MG sets.  From the "Power Supply and
Distribution Manual"

(http://bitsavers.org/pdf/ibm/7090/ce/7090%20Power%20Supply%20Control%20and%20Distribution%20223-6904.pdf,
page 5):

"The IBM 7608, a power converter or motor-generator set which converts
incoming 60-cycle three-phase (3Ø), 208v power to regulated 400-cycle 3Ø
208v power."
