Three-phase asynchronous motor In the event of failure, there will be some abnormal phenomena, such as a sudden increase in temperature; When we check and eliminate the motor fault, we should first carefully observe the motor, understand the abnormal phenomenon after the fault occurs, and then analyze the cause of the motor failure, find out the problem, and then eliminate the fault, the following Senli motor Xiaobian to share some Three-phase asynchronous motorCommon fault phenomena and troubleshooting methods:
       Note: If the motor fails, please be sure to be handled by technical personnel, strict non-technical personnel privately, otherwise it may cause personal and property losses.

       one. After being powered up Three-phase asynchronous motorCan not turn, but no noise, no smell and smoke. 

       1. Failure cause analysis:
       ①Power failure (at least two phases failure)
       ②Fuse blown (at least two phase blown)
       ③The overcurrent relay is too low
       ④The control device is improperly connected

       2. Troubleshooting cause: 
       ①Check the power circuit switch, fuse, junction box for breakpoints, repair
       ②Check the fuse model, the cause of the fuse, and replace the fuse
       ③The adjusting relay setting is matched with the motor
       ④Correction connection

       two.After being powered up Three-phase asynchronous motorDon't turn, and then the fuse burns
 
       1. Failure cause analysis:
       ①Lack of a phase of power supply, or a fixed main ring a reverse connection
       ②Stator windings interphase short circuit
       ③Stator winding ground
       ④Incorrect connection of the stator winding
       ⑤The fuse section is too small
       ⑥The power cable is short-circuited or grounded

       2. troubleshooting:
       ①Check whether there is a phase of the brake is not good, but the power circuit has a phase break line; Remove the reverse connection fault
       ②Locate the short circuit and repair it
       ③Grounding exclusion
       ④Find out the misconnection and correct it
       ⑤Replace the fuse; ⑥Exclude the ground point. 

       Three-phase asynchronous motor Regular maintenance and overhaul is needed to avoid and reduce sudden damage accidents.
