Agreed. Max output power of a (denso) window motor is about 85W, or 63 ft-lb/s. Even if you managed to get its output at its best speed to the totes with those weightless, frictionless components you get to use in intro physics class, that would raise six totes (47 lb) at about 16 inches per second. Using real gears, chains/belts, and a lift plate, the answer is quite probably zero. Further, we have had window motor gearboxes nearly explode when we've tried to get too much out of them.

A CIM drawing 40A has about three times the power of a window motor at its maximum. If you're hoping to lift six totes briskly, one of these is probably not enough.
