Z4 high
voltage big dc motor of motor supplierI. Brief introductionZ4 high
voltage big dc motor of motor supplier from China are widely used
for prime mover in various fields, such as mill auxiliary in
metallurgical industry, metal cutting machine-tool, paper making,
print, textile, printing and dyeing, cement-making, plastic
extruding machine, etc. .II. Performance condition Data listed
in the technical data sheet should be employed under the following
conditions;a. Altitude above sea level maximal 1,000m;b. Cooling
air temperature maximal 40 oC;c. Ambient conditions for motors
should be free from acidic, alkali fumes or other aggressive gases
which corrode insulation.d. Duty: Continuous (SI);e.monthly average
temperature would not be more than 24 degree celsius.and r elative
humidity: monthly average no more than 85%.III. Performance1. The
standard rated voltage of the electromotor are 440V, 550V, 660V,
750V etc. Voltage of other classes can also be derived according
specific situation, but must be negotiated when ordering.2. The
basic excitation style is separately excited, the excited voltage
is 220V, Voltage of other classes can also be derived according
specific situation, but must be negotiated when ordering.3. Short
time overload capacity of motor.Motor can be divided into two kinds
according to the useFirst kind (A): ordinary industrial DC motor;
Second kind (B): metal rolling mill DC motor.a) First kind (A)
motor can endure the overload (1min) according to table 3Table

bracket.5. The change rate of current6. Libration and noise7. The
efficiencies listed in the data sheet are for rated output, voltage
and speed, and include excitation loss.IV. Structure . The
methods and defend class of the motora) The method of cooling of
the motor is separately-cooled, according to the GB/T1993 "Method
of cooling of rotating electrical machinery", there are IC06, IC17,
IC37, IC86W. Standard entrance of cooling air is at the end of the
main transmission (not the commutator side).The defend class of the
motor can be divided into IP23 and IP44 according to the GB/T4942.1
"the crust defend class of rotating electrical machinery (IP
code)". If the user needs other method of cooling and defend class,
it can be negotiated. c)The cooling wind, wind pressure,
cooling water flux, motor power see Table

installation and the type of motor according to the GB/T997 "The
structure and installation type of rotating electrical machinery",
haveIM1001 (horizontal bottom install, column biaxial) and IM1002
(horizontal bottom install, column biaxial). If the user needs
other kinds of installation structure, it must be negotiated.3. The
position of terminal box on standard motor is on the right side
when seeing from the main drive end. It can also be installed on
the left side, but it must be written in the order contact.4. The
motor using rolling bearing, nonstop adding oil structure.5.The
motor can be installed the following accessories at the user's
optiona) Temperature detector component can be put into the stator
winding and bearing room of two side, and connect the outlet wire
to the terminal box.b) The non-drive part of the machine can
equipped with tachogenerator, centrifugal starting switch, coder
and others which buildup the speed meter protecting device.c)
Heater for preventing condensation can be installed in the motor,
but it must be written in the other contact.6. The air-to-water
heat exchanger is usually installed on the top of the motor. If the
user wants it to be installed on the side of the motor, the user
must put forward it when ordering and settle the assistant upholder
by the user himself.7.The cooler equipped with wind pressure
switch, temperature controller, heater for preventing condensation
and other protect device.V. Company introductionChina Electric
(Shanghai) Co., Ltd. is established since 1960s with over 8-year
experience in export in Alibaba. We locate in Shanghai and has more
than 1000 employees. Its factoryis about 30,000~50,000 square
