General
1.1 The instruction is suitable for ZD series large scale
DC motor and its derived products.
1.2 The insulation class of this series motors is F class.
The armature and stator coil are both made vacuum pressure
integral impregnated (VPI).
1.3 The excitation type of motor is separately excited.
There are two kinds of regular excitation voltage, and
they are 220V (in series connection) and 110V (in parallel
connection).
1.4 The name of motor terminal mark as follows:
Initial end Terminal
Main loop A ¡ª¡ª C
Excitation loop F1(5)¡ª¡ª F6(2)
When markF1¡¢F2¡¢F5 and
F6 in connection diagram at the same time,
short circuit F2 and F5£¬F1
as initial end£¬F6 as terminal£¬hereby the
excitation winding is in series. When shorting circuit
F1 and F5 as initial end£¬short circuit F2
and F6 as terminal, hereby the excitation winding
is parallel connection. The mark of thermometric element,
space heater and etc., please refer to relevant documents.
1.5 The cooling type of motor are IC17£¨Duct ventilation,
open circuit ventilation£©, IC37£¨Duct ventilation at
both ends£©, and ICW37A86£¨with water to air cooler£©¡£
1.6 The mounting type of motor is IM7311or IM7321£¬that
is, put rotor on two pedestal slip bearings, and together
with stator installed on the same soleplate (Soleplate
has integral type and partitioned type). Bearing lubrication
is divided into oil ring lubrication, compound lubrication
(oil ring and adscititious low voltage circulation oil¡ªsupply
by lubrication station£©£¬and static pressure bearing
lubrication£¨oil ring and adscititious low voltage circulation
oil and high voltage circulation oil¡ªsupply high and
low voltage circulation oil by the same lubrication station£¬and
the high voltage circulation oil is for supporting rotor
to form oil film£©. |
