High-voltage motors have used in many places, but often it is not functioning up some failures. So we usually have to accumulate a little more experience, then you can solve problems faster encountered problems.

     Xiao Bian now to summarize a few common questions we often encounter, and attach solution. High-voltage motors usually prone to problems are:

     1, the power of the motor does not rotate, but no abnormal sound, no smell and smoke.

     2, the power of the motor does not turn, then the fuse is blown

     3, the motor does not turn buzz after power

     4, the motor start-up difficulties, the rated load, the motor speed is lower than the rated speed more

     5, the motor load current imbalance, phase difference between the large

     6, the motor idling, when overloaded, ammeter pointer swings, swing

     7, the motor load current balance, but the big value

     These are the high-voltage motors usually seven questions arise.

     1, the power does not pass, the fuse is blown, overcurrent relays too small, wiring errors

     2, the lack of a power supply, the stator winding shorted to ground, the fuse section is small, the power short circuit

     3, sub-windings open circuit, the power supply voltage is too low, bearing jam

     4, the voltage is too low, open-cage rotor welding or broken, motor overload, excessive increase in the number of turns the motor windings and other repair

     5, the three-phase stator winding turns are not equal, inclusive winding termination wrong group exists between turn short circuit, reverse polarity, such as coil failure

     6, cage rotor bars open welding or breaking, wound rotor failure

     7, the power supply voltage is too high, the gap is too large or uneven
