Remember that magnetic steels have hysteresis. When the magnetizing field is removed, the steel still acts as a weak permanent magnet. (We've all seen this too often when we use our pliers and screwdrivers around a strong magnet, after which the tool is forever picking up metal filings.) On a 2400 volt motor, I have little doubt that this residual field is quite sufficient to generate lethal voltages.
