dewalt motor VS. CIM motor

[Joe Johnson]

I have never seen a spec on the Dewalt motor that comes with the XRP drill, but my considered opinion is that it is close to a 400W motor which would make it a higher power motor than the CIMs.

Note that 400W is a theoretical number that is calculated as the power produced by the motor at the peak mechanical power output of the motor (loaded at 1/2 stall torque and therefor running at 1/2 its free speed).

As a practical matter, I think that that motor will not be able to sustain 400W without overheating. So while the motor may be theoretically a higher power motor than the CIM, I think that in many cases you can get more actual power out of a CIM (especially if your application is for high power over extended periods of time).

Calling 'em as I see 'em.
