Technical Specifications

Ventilation and Cooling
A new design was developed to improve
heat transfer with a low-pressure drop
Rugged inside and out.
Viton
®
is used to seal commutator bands, preventing
penetration of contaminants into critical areas
Grease relief plug prevents forcing of excess
grease into internal parts of the motor
Cartridge-type bearing assemblies protect bearing
from dirt and contaminants during
overhaul
Drain holes allow excess moisture to drain
from bottom of motor
Commutator risers are TIG welded to armature
conductors for higher overload capability
Proven GE commutator design has greater stability
for severe MD motor applications with improved
tracking resistance
Constant-pressure brush holders help to assure
excellent commutation without
spring pressure
adjustment, reducing
maintenance
