Rewinding the stator of the Pilger heavy duty DC electric motor

• Wood

Eltra MG carries out demanding works of rewinding the stators of Pilger DC electric motors, specially intended for the railway industry and heavy-duty traction motors. These electric motors require high precision, quality insulation and reliable workmanship due to extreme operating conditions.

Description of the works performed

• Dismantling of the stator winding and detailed inspection of the stator core
• Analysis of the insulation condition and detection of any local damage
• Manufacturing and installation of a new stator winding using high-quality insulating materials
• Application of an insulation system adapted to heavy operating conditions and high current loads
• Impregnation of the winding with resins and varnishes of the appropriate thermal class
• Final electrical tests: insulation resistance, absorption factors, inter-turn tests and high DC voltage test
• Preparation of the electric motor for safe commissioning

Benefits of the rewinding performed

• Complete renewal of the stator insulation system
• Increased reliability and safety of the electric motor
• Extended service life of the unit under demanding conditions
• Reduced risk of failures and unplanned downtime

Eltra MG combines expertise, many years of experience and modern technologies in order to ensure top-quality rewinding and long-term reliability of Pilger heavy-duty railway electric motors.
