Rail (traction-motor cooling). Cooling on the move.
Rugged motors for locomotive traction-motor cooling blowers.
Background: representative footage
The duty
Rugged, reliable cooling.
An electric locomotive carries two traction-motor cooling blowers, each cooling one group of three traction motors. The blower and its motor are among the most important auxiliary machines on board.
These motors are rugged in construction and extremely reliable. We supply them to the companies that build the blowers.
Applications
What the duty demands
- Full cast-iron construction, IP66
- Vibration and shock on rolling stock
- Long service intervals
