When measuring rotor winding interturn short circuit fault of use method

Put the rotor under test in a test in the mouth,make the motor spare parts turn-to-

turn short circuit energized tester,tester within the closed magnetic circuit core and rotor core has

alternating magnetic flux,and if there is no short circuit,magnetic flux through the coil of the

coil,there is no short www.dongfeng-motor.com circuit current,on the small iron

notches (small hacksaw blade vibration will happen.If the coil turn-to-turn short circuit,word small plate,vibration will occur when the rotating rotor,one can find out all the short-circuit coil

slot."Little experience" When small plate vibration,should be cleaned motor

laminationup mica slot commutator conductive material (such as charcoal powder),then test

again,in order to avoid miscalculation.When measuring rotor winding interturn short circuit fault of use method.
