It would seem that it was originally wired for 220V 3-phase at 2.8 Amps, and that it had been rewired later for 440V at 1.4 Amps. But it is unwise to believe everything one reads. In fact the motor is wired for 220V 3-phase. (Attempting to run it at 440V simply results in a rapid temperature rise which trips the machine's breaker in under a minute.)
