Key Technology of Traction Motor
Technical Development of Traction Motor
Two-circuit cooling system for an enclosed traction motor
Conventional self ventilation type traction motor
An Enclosed Traction Motor vs. Open Type Traction Mo tor
Heavier and larger than same capacity self-ventilation type traction motor (without forced cooling systems)
Lighter and smaller than same capacity enclosed traction motor (without forced cooling systems)
Longer maintenance interval
Shorter maintenance interval, but practical maintenance interval is 3 year overhaul and 6 year heavy overhaul.
Higher maintenance cost reflecting that the structure of motor is some complicated
