Re: (ET) More lift motor observations

["Konstanty, Walter \(GE Consumer & Industrial\)" <Walter Konstanty ge com>]

   Can you let me know the model number of a lift motor??
Since I work for GE Motors I may be able to get some specs/info on them to 
help us all out.
I do have info on the E15, E20, and snowblower motors which I'll send to 
the website soon.
Running motors at higher than rated voltage causes them to run higher 
speed by the same ratio - that 
increases load/current as this is a constant torque application (load 
stays same with speed).
Also, these are not continuous load capability motors......intermittent 
duty at best.
