"...D.C. or 25 to 60 cycles."

Excluding DC, I know of no power
company that  commercially produced
electricity with a frequency of less than
25 cycles.   There might have been?

Would such an "AC or DC" series motor
give a rat's fanny if it was fed less than
25 Hz?

Heck, it'll run on DC!     That's zero Hz!  :shock:

Would frequencies between DC and 25 Hz
fry those motors?    I don't think so.
