Most of the medium sized motors run at slightly below line rate, and often at 
half of line rate.  I'm thinking of the classic squirrel cage induction motor 
vs a synchronous motor.  A quick google search found 1725 and 1750 RPM.

Is it possible to measure things accurately enough to notice that?

These are my opinions.  I hate spam.
