Re: Common Motor/Gearbox Reference Sheet

There is something I have been wondering about this information, if someone could enlighten me.

The Stall Current and Max Power values don't seem to line up. For instance the RS-550 motor pulls 85A at stall. Given a 12V supply, the power consumption should be: 85A x 12V = 1020W. But the value listed for Max power is significantly lower at 254W.

I know that at stall a motor acts like a (small?) resistor and that without the back EMF resistance the current draw jumps up. Do the Max Powers listed only apply to non-stall situations?
