──Mar 30 , 2021Three-phase asynchronous motor does not turn what is the reason (1)

       When we found outThree-phase asynchronous motorWhen we can't start, we can judge the reasons for not turning through some methods, and we can check and find out the reasons from the following pointssendynamoLet's learn about it.

       Here are five points that can lead to Three-phase asynchronous motorReasons for not rotating, if there are reasons not summarized welcome to add:

       1.Power supply is not connected: the power supply is not connected or the contact is poor resulting in the motor will not rotate, at this time we should seek the help of technical personnel, check the switch, fuse, contact and wiring, the fault will be gradually eliminated and then maintenance;

       2.On start-upThree-phase asynchronous motorIf it is found that the fuse is not turned by the fuse, it is necessary to find out the cause of the fuse, and install the fuse of the same specification according to the capacity of the motor;

       3.Overcurrent relay setting current is too small, should be adjusted higher;

       4.The load is too large or the motor structure card causes no rotation, and it is necessary to choose a larger capacityThree-phase asynchronous motorOr reduce the load and check the transmission condition;

       5.If the stator or rotor winding is disconnected, open the junction box and check whether the motor winding is disconnected (wire is broken) with a multimeter ohm. If there is a disconnected circuit, there will be an abnormal resistance value, which needs to be openedThree-phase asynchronous motorFurther check the disconnect point, connect well;

       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.
