Troubleshooting Elektro Motor

Troubleshooting Problems Causes Solutions The motor fails to start Overload Reduce load One phase of the supply power breaks down Check the distribution equipment and the fed circuit Connections of the stator winding isn't correct Correct the mistakes of windings connected The motor is difficult to accelerate Overload Reduce load One phase of the supply power open Check the distribution equipment and the fed circuit Low voltage and high frequency of network Improve the condition of the supply system Interturn short circuit or inter phase of stator windings The insulating resistance of the windings should be checked. Repair it after having asked the manufacturer Connections of the stator winding isn't correct Correct the mistakes of windings connected Buzzing noise occurs during start of the motor One phase of the supply power open Check the distribution equipment and the fed circuit Interturn short circuit or inter phase of stator windings The insulating resistance of the windings should be checked. Repair it after having asked the manufacturer Connections of the stator winding isn't correct Correct the mistakes of windings connected Buzzing noise occurs during operation Overload Reduce load One phase of the supply power open Check the distribution equipment and the fed circuit Interturn short circuit or inter phase of stator windings The insulating resistance of the windings should be checked. Repair it after having asked the manufacturer Connections of the stator winding isn't correct Correct the mistakes of windings connected Buzzing noise occurs due to periodic double-slip Bars of squirrel cage are thin and broken Repair after having asked after the manufacturer Excessive temperature in operation at no-load High voltage and low frequency of network Improve the condition of the supply system Excessive temperature in operation at load Overload Reduce load One phase of the supply power open Check the distribution equipment and the fed circuit Connections of the stator winding isn't correct Correct the mistakes of windings connected
