Product Description
D Series Large Size DC motor used polygon structure so that the
using rate of the stator's inner space is very high. The magnet
yoke is laminated style, suitable for silicon controlled commutate
power supply and it can endure pulsating current and rapid change
of current (load change).Magnetic poles are fixed by precise
orientation. All the motors of system are with compensate winding,
so the reverse performance is very well.
The insulation class of the motor is F,using of reliable insulation
structure and nonmenstruum vacuum pressure impregnated,guaranteeing
the stable performance of insulation and good heat
dissipation.
Product Feature
1.Data listed in the technical data sheet should be employed under
the following conditions:
a) Altitude above sea level maximal1,**0m;
b) Cooling air temperature maximal *0C; Cooling water temperature
maximal *2C;
c) The motor can be installed under foul situation, but the right
cooling method of cooling method of cooling and defend class must
be chosen. If the situation is special, need humid tropic, please
negotiate.
d) The motor is suitable for *-phase bridge style smoothing
reactor, also can adopt power supply of DC generator.
e) The motor accord with GB**5 "The ration and performance of the
rotating electrical machinery", IEC******1 "The ration and
performance of the rotating electrical machinery" and JB/T***7
"Technical requirements of D series middle motor electromotor";
2.The standard rated voltage of the electromotor are **0V, **0V,
**0V, **0V etc. Voltage of other classes can also be derived
according specific situation, but must be negotiated when
ordering.
3.The basic excitation style is separately excited, the excited
voltage is **0V, Voltage of other classes can also be derived
according specific situation, but must be negotiated when
ordering.
4. Short time overload capacity of motor.
Motor can be divided into two kinds according to the
use
First 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 3
c)The short time overload capacity seldom used means happens
infrequency or only at the urgency, the motor working exceed the
continuous rated overload capacity, we suggest you adjust the
instantaneous open/close device of the switch according to the
short time overload capacity seldom using.
The short time overload capacity seldom constantly
used means its an part of the normal working period, the motor
endure the continuous rated overload capacity again and again.
After working at short time overload, it must working light load to
make the overload periods overload root-mean-square less than its
continuous ration.
d)Second kind DC motor(B)can endure the following
continuous load; Working continuous within the rated voltage and
rotate speed with **5% rated power overload, the temperature is
higher when at this overload, other features maybe different from
working at the rated condition.
Within the rated voltage and rotate speed, after
running at the rated overload, working at the **5% rated power for
two hours, the temperature rise cant overrun the regulated
numerical value other features maybe different from working at the
rated condition.
e)Second kind DC motor(B),at the rated rotate speed,
the overload can reach 2.5 times no longer than *5s only used once
in a while.
5.The change rate of current
Under all rotate speed and load, the change rate of current (di/dt)
that the motor can endure is **0 times rated current.
6. Libration and noise
a) the libration of the motor accords with GB****8"Measurement
evaluation and limits of the vibration severity of rotating
electrical machines which the shaft center height is *6mm and
above" center standard's regulation.
b) The noise of the motor accords with GB****9.3 "Measurement of
airborne noise emitted by rotating electrical machinery and noise
limits".
7. The efficiencies listed in the data sheet are for rated output,
voltage and speed, and include excitation loss.
The choice of the motors capacity
1.First kind (A): Ordinary industrial DC motor. The
technical data of this kind of motor please see the technical data
table. The buyer can decide the capacity, voltage, running speed
and the method of cooling of the motor at the buyers option.
2. Second kind (B): Metal rolling mill DC motor. The
output power of this kind of motor is about *0% lower than kind
(A), the detail numerical value can be negotiated by the user and
the manufacture.
3. Exclude the specification of technical data in the
table. Manufacturer can derive other specification at the
requirement of the user.
