TROUBLESHOOTING MOTOR UNBALANCE - .

Deze pagina vertalen

6/06/2019 · Electric motors are almost always well-balanced when they leave the motor manufacturer. But occasionally, motor unbalance problems are picked up with vibration monitoring tools, such as the OneProd Hawk. Here are some easy troubleshooting methods to determine the cause of unbalance in the motor. An electric motor's rotor, like any rotating mass, cannot become out .

In my July 2014 column, I demonstrated that three-phase voltage variation can significantly affect several alternating current (AC) motor characteristics.If that variation is large, it can also reduce motor life. Voltage unbalance can be an even bigger problem and is one of the major causes of premature motor .

Shake-out systems in foundry or hopper discharge feeders are also important applications. The unbalance motor creates a centrifugal force the vector of which rotates at the speed of the motor round the shaft of the drive motors. A circular movement is created. Two unbalance motors driven contrarily are synchronized and create a targeted force.

voltage unbalance also causes an increase in current unbalance well in excess of the voltage unbalance percentage. Fig. 1 shows how motors should be de-rated based on the percentage of voltage unbalance. Variable speed drives (VSD) may trip off due to an increase in AC line currents caused by a compensation for the voltage unbalance.
