What are the characteristics of three-phase motor windings in the reverse connection?
In three-phase windings, if one phase winding is called a tail swap, instead connected. On the contrary, the main features are as follows:
1 motor starting torque serious decline. As long as a load or low voltage, the motor will not start to normal operation;
2 three phase load current is significantly different, and it is much greater than the normal value;
3 severe vibration of the fuselage and has obvious electromagnetic noise;
4 even if the no-load operation, motor to severe fever, if not timely power, motor burn out easily.
Therefore, when found in the contrary, it is necessary to check, find out and correct.
