Putting the coils made in H insulation class into rotor channels with AC electromotor ISVK 644-8, with power of 850 kW, 770 V and 1100 rpm.
|
We provide services of mainteninance, servicing and fixing of electromotor and generators on electrical locomotives 441 and 461 series and diesel electrical locomotives 661 for ex Yu, Turkey, Bulgaria and Romania.
 |
Pulling engine ISVK-8, power 850 kW, 770 V and 1100 rpm serries 441 after general remont and final testing prepared for delivery. |
After servicing or remont of pulling electromotors of electric locomotives, they go to diagnostic station which works for electromotors loaded and unloaded.
 |
Diagnostic station for testing the pulling electromotors ISVK 644-8 from the locomotive 441 series with possibility of tracking and measuring of electrical, mechanical and thermal values in real time. This station is creation of employed engeneers . |
