Rotate the rotor shaft to see its free motion and check the bearings and play. Rotor shaft may be jammed in the bearings or brushes.
Single phase motor winding checking series#
Open circuit in relay circuit or centrifugal switch.Ĭheck with a test lamp in series of the supply and correct them.Ĭapacitor may be defective in capacitor type motor.Ĭheck the capacitor with a series test lamp and replace it. correct them by doing the connections of ends of each coil polarity. join it or solder it and if the polarity is wrong. Stator winding may be open-circuited or reversed coil connections.Ĭheck the windings and polarity of coils with the test lamp and if any end is found broken. Rotate the rotor by hand and if it is free to move, then reduce the load.

Be sure to contact the motor manufacture for best practices when applying a megger to the motor. To perform the insulation resistance test using a meghommeter, follow the steps below:ĬAUTION: Working with live electrical components requires the proper PPE to be worn and all safety precautions taken into consideration.
