Laminations and commutator are stripped
Replacement armature coils are insulated
from the laminations with Nomex to meet or
exceed the O.E.M. specifications.
Armatures are dipped in Class "H" varnish
and baked before final assembly.
Each armature is turned and undercut to
the proper depth to extend the operating
life of the motor, to prevent premature
shorts and to increase brush life.
After tension banding with Permafil
treated glass banding to hold coils in
place, the commutator is faced and the
armature assembly is completed by brazing
the coil and commutator.
Finally, the completed armature is both
ground and bar-to-bar tested to assure the
