WebAugust 20, 2007 What Causes Inductive Imbalance in Wound Rotor Motors? Although shorted turns in the stator windings can be a source of a high imbalance, inductive imbalance seen on the stator windings of a wound rotor motor can often be the result of a fault in the rotor field or resistor bank. WebThis will adversely affect the Standard Test results, possibly creating higher than normal resistive and inductive imbalances. Wound Rotor Electric Motor Testing Wound rotor motors have a three-phase winding wound on the rotor which is connected to three phases of start-up resistors in order to provide current and speed control on start-up.

Web10 jan. 2024 · The electric company that responded used a state-of-the-art technology in electric motor testing—PdMA’S MCEMAX ® —that uncovered an inductive imbalance in the stator winding. The technology then promptly identified the culprit—two reversed leads causing a phase inversion and a reverse torque that opposed the normal rotation. Web30 jul. 2024 · I had to walk an electrician, and subsequently a junior technician, through the diagnosis of a three phase motor problem today. There is one part of the situation that I am trying to work out for myself. It was a 15hp 480V motor with a mag starter and no drive. The starter heaters were tripping and shutting down the starter. They told me that it was … Web21 jul. 2024 · On some motors, the normal inductive imbalance could be much lower than 8%. On other motors, the Inductive Imbalance may be significantly higher than 8% without indicating a fault. Comparing to a baseline test is the best way to determine whether the … debugging react application
