The smaller the working lift, the lighter the load of the motor should be. There's nothing to say. Your motor burned three sets, probably not the motor. First of all, you didn't protect the motor well. The overcurrent relay should be installed and adjusted to the rated current of the motor. If it's not the problem of lack of phase or machinery or pump, the working current of the motor should be below the rated current; Whether the factory voltage is above 380, whether the motor is easy to get water, etc. If not, there are only two reasons: first, whether the circuits of the motor are out of phase but not obvious; Second, whether the resistance of the pump is too large (it should be easier to turn the fan blades of the motor), and the resistance of the pipeline will greatly exceed the rated current if it is bent too much. Or the outlet pipe is too small and the resistance is too great. These remedies should be within this range!
