Everyone knows that the winches are used with 380V three-phase electricity.

We all know hoist winch hoist is 380V three electricity use, particularly where the use of winches, can be used with small gantry use, can be used with 1-10 tons of outdoor are three electricity use, particularly where the use of winches, It can be used with a small gantry, or with a 1-10 ton outdoor multi-function hoist, multi-function hoist, multi-function hoist bracket, but in the process of using the hoist, the motor is always burned out for no reason.

There is no lack of phase power in the three-phase voltage, so it is possible to eliminate the burning of the hoist caused by the voltage instability, which is most likely to be caused by the motor heating and burning caused by the motor sweeping, which has a lot to do with the bearing.

Motor sweeping means that the rotating rotor of the motor rubs against the stator when the motor is working, resulting in a substantial increase in temperature, burning out the windings, destroying the insulating paint, and finally burning out the motor.

The hoist motor sweeping bore is said to be bearing problems, but there are also several different manifestations.

This kind of motor is not concentric or the shaft is bent, which will cause sweeping.

The second type: the second type: 3 ton hoist, 3 ton hoist, 3 ton hoist, 3 ton hoist, ton hoist , the bearing will gradually wear out after long-term use, the cage will fall apart, and it will be easy to sweep the bore.

The third type: if the bearing goes inside and outside the circle, the rotor shaft is thin in the inner circle, and the end cover chamber is large in the outer circle, which may cause bore sweeping.

The fourth type: the bearing balls are scattered, the bearing shakes, the problem is not big, just change the bearing, and the friction between the rotating shaft and the bearing becomes thin for a long time, and the friction between the end cover and the bearing becomes larger.

    If the hoist motor is not severely cleaned and the rotor is polished with a grinder, then it will be fine.

    Some may say that another motor does not so much trouble, Xiao Bian want to say one might argue that there is no change in the motor is not too much trouble, Xiao Bian want to say a winch price hoist price hoist prices expensive may be thousands It would cost thousands or even tens of thousands of dollars to change a motor, so many people are reluctant to change to a new motor and look for the reason why the hoist motor burns to correct it.
