Identification of the cause of the fault

At the beginning of analyzing electric, measure the winding resistance, insulation resistance against chassis, test compound between the windings and perform other necessary measurements. Follows the detection of engine failure. The engine apart and look for fault with the naked eye.

Peparation and Purification

Code generators and electric motors failure causes most worn bearings, or a breakthrough between the two phase windings. Remove the old coil, clean insulation, sand stator, remove shudder from the slot and, if necessary, sandblast the inner part of the stator.

Building insulation, winding and impregnation elements


Make a new profile insulation class H. The inside stator coat paint to prevent peeling old paint and increased dielectric strength. The following is an implementation windings. If the motor winding is still an original, copy the data factory-section wire, coil, coil binding, etc., Or if the engine has already been viklovan, data re-calculate and verify their accuracy. The coil is put into the stator and produce intermediate isolation. The following binding and impregnating windings.

Renovated electric motor-generator, ready for reinstallation

The figure below shows the restored generator with a new coil. The following is just a slight impregnation and drying in an electric furnace. Upon completion of the drying is carried out testing: stator resistance, the test circuit between coils, dielectric strength test and measuring insulation resistance against chassis.
