The free-speed of a CIM motor is about 5500RPM according to
http://www.firstwiki.net/index.php/CIM_motor
which is about what the motor would spin at if an eccentric mass (it's not really a cam) were mounted to it. Doing a little math shows...
5500 cycles/minute * 1 minute / 60 seconds = 91.7cycles/second [Hz]
Take off a little fudge factor for increased bearing load, and because round numbers are nice, you've got a vibration source of about 90Hz.
I will not, however, try to figure out the 3D non-linear vibration of the table
