The causes of an electrical fault may be a lot of,it is important to find out the main reason in many reasons,and use approach to troubleshooting.For example,a three- phase cage asynchronous motor fault functioning,whatever the case,is the most concentrated performance motor does not work,but is not necessarily in the motor fault,and may be a power failure,may also be the failure of circuit or equipment and components.That is to say,the same failure form,failure of a variety of reasons.In these reasons,which is what reasons make the motor can't work,even after a deeper and more detailed analysis.For example: if the motor is used for acmotortrading.blogspot.com the first time,it should check power supply,circuit,the motor and load analysis; If the motor is used for the first time after repair,it should start from the motor itself check analysis; If the motor is running for a period of time suddenly can't run,it should check points off power supply and control components.Through the above process,then determine the specific cause of motor fault.
