More than likely that won't be listed anywhere.. You need to weigh it.

Or call the OEM.

In my experience you are more likely to find the total motor weight in catalogs etc. and perhaps the rotor inertia for torsional modeling.   I have seen a "rule of thumb" that the rotor weight is about 1/3 total weight within ± 5%.  Very much dependent on the design of the motor, hence the probable reason for the ± 5%.
