Does anybody know where we can get the specs on this year's cims?

Does anybody know what the maximum operating temperature for them is?
How dangerous is it if we do overheat them?

The CIM motor data from 2005 is here.

Note that the normal load specified for this motor is 64 oz-in torque, and the specified current draw at that load is 27 Ampere. Note also the endurance test conditions specified (under the heading Special Features near the bottom right of the drawing):

So the CIM's manufacturers indicate that motors of this design were tested by running the following load cycle:

1) Apply +12V between the red and black leads and load the shaft at 64 oz-in for three minutes,
2) Remove the voltage for two seconds,
3) Apply -12V between the red and black leads and load the shaft at 64 oz-in for three minutes,
4) Remove the voltage for 30 minutes,

and then repeat steps 1 thru 4 until 1000 cycles are complete.

My understanding is that the CIM was developed as a winch motor. In that application it is often operated intermittently beyond its normal load.
