The appearance inspection found no fault point,can according to the fault phenomenon,combined with the circuit diagram analysis of the cause of the problem,permanent magnet motor in expanding the scope of the fault,damage under the premise of electrical and mechanical equipment,direct current experiments,or remove load (off) from the control box terminal plate electric test,in order to distinguish the fault may be in electrical parts and machinery,and other parts;Is on the motor and control equipment;Is in the main circuit and control circuit such as contactors and motor movements,the fault in the main circuit;If contact not suck,fault in the control circuit.Usually check control circuit,particular way is: a button or switch operation,circuit in motor run capacitor the contactor,relay will take place according to the order of the work.If,in turn,moves to a certain electrical components,found that do not conform to the requirements,both show that the electrical components or the relevant circuit has a problem.In this circuit,item by item analysis and check again,usually can find fault.

To control circuit electricalmotor1.blogspot.com troubleshooting back to normal again after turn on the main circuit,check the main circuit of the control effect,to observe the performance of the main circuit with and without exception,etc. In the current test,must pay attention to personal and equipment safety.To abide by rules of safe operation,shall not touch the live part,as far as possible to cut off the electric power main circuit,only under the permanent magnet generator condition of the electric control circuit for inspection;For motor operation,should make the motor under no-load operation,to avoid the movement of industrial machinery parts misoperation and collision;To temporarily partition defective main circuit,in order to avoid failure,and fully estimated in advance to the local line movement after the possibility of adverse consequences.
