eachThree-phase asynchronous motorThere will be more or less shaft current, but it will not harm the normal production operation; Some inverter motor power module switching frequency is high, the resistance of the split capacitor is small, the peak current is large, and it is easy to form "washboard pattern". belowAsynchronous motor manufacturersSenli motor will take you to understand the motor shaft current.

       oursAsynchronous motorUnder normal conditions of operation, three-phase AC motor, in the three-phase symmetrical winding flow is three-phase symmetrical current; At this time, the magnetic fields at both ends are symmetrical, there is no alternating magnetic field of the alternating chain of the motor shaft, and there is no potential difference between the two ends of the shaft, and the current at this time is not through the bearing; However, if the symmetry of the magnetic field is broken, then there will be an alternating magnetic field of the alternating chain motor shaft, resulting in an axial current.

       Shaft current is related to asynchronous motor design, and also related to the matching voltage and production situation in actual use, so now many motor manufacturers in order to prevent shaft current problems, take defensive measures on the motor, do not look at these seemingly "redundant" measures, in fact, in order to ensure the reliability of motor operation.
