Continue to run on 2 phases, draws excess current, winding likely to burn

Run at reduced speed and can take only 2/3 of the load

The new motor will be overheated

The new motor is better suitable for this work

The efficiency and the power factor will become low

The new motor has a longer useful working life and efficiency
