4-16-7 Balance. The rotor assembly is precision balanced to a high degree of static and dynamic balance. Balance is
achieved with the balance lugs on the field pole tips. The balance will remain dynamically stable at speed in excess of the
4-16-8 Bearing. The generator rotor assembly is suspended on shielded, factory lubricated ball bearings. They are
greased for life and do not require lubrication.
4-16-9 Stator Assembly. The stator assembly consists of laminations of steel mounted in a rolled steel frame. Random
wound stator coils are fitted into the insulated slots.
Make sure unit is completely shut down and free of any power source before attempting
any repair or maintenance on the unit. Failure to follow this procedure could result in inju-
ry or death by electrocution.
