Basis of local life extension method insulation of electric machines of locomotives thermal radiation

The main damaged knot of traction electric motors of a traction rolling stock is isolation, namely in the field of the basis of front part. The imperfect system of isolation in face part of front windings results in humidity. Also the increased intensity in this zone is the reason of low reliability. Authors propose the system of local insulation encapsulation energy of infrared radiation as life extension activities of electrical machines.
