REPAIR OF RAILWAY ELECTRIC ENGINES

The collector of the DC electric motor is made of collector copper plates, isolated from each other and from the case by micanite gaskets and cuffs.

The anchor winding is made of rigid sections, made of PSDKL wire. The insulation system uses modern electrical insulation materials with heat resistance class "F", impregnation based on organic silicon compounds.

The coils of the main and additional poles are made of PSDKL wire. In the insulation system, electrical insulating materials impregnated with organosilicon varnish are used.
