after a period of time, the heating of the motor leakage protection trip (acceptedwithout good). After cooling for a period of time, is it possible that the motor insulation value is small? 20Vertical rammer, after a period of time, the heating of the motor leakage protection trip (acceptedwithout good). After cooling, can use for a period of time again, is the motor insulation value small and overloaded?
Hello,- * the motor insulation has reached a critical point, the maintenance of electrical insulation properties...... according to explanation, the electrical insulation resistance with temperature rising and declining trend. It is obvious that the insulation of this motor has reached the limit of the leakage protector. It should be repaired immediately so as to avoid accident due to the malfunction of the protector.
Is the old, poor mechanical properties, motor overload, leakage protection if it can be adjusted to adjust, can not maintain the tone on rammer, change a little larger leakage protection, can be, the original motor is not hot, do not pay attention to is the trip.
Now the motor really dare not praise ah! The former are copper enameled wire, and now a lot of aluminum enameled wire ah!
