Web19 feb. 2024 · I don't recall ever seeing a bad motor cause phase loss faults. But stranger things have happened. I suppose if the motor had a shorted phase, it could be pulling the DC bus down on the same input cycle every time, (if the ouput is 60hz) which would appear as a loss of input phase. But I would expect an output current fault to occur first. WebEffect of Single Phasing or One Phase Failure on Three Phase Machines. Electrical machines will operate at a considerably reduced speed, under power and produced toque. Due to the loss of one phase, the current in the other two phases will increase. This causes heat up the motor winding and insulation failure which leads to a short circuit.
