D2 series DC motor
Series D2 DC machine is used for industry. It’s suitable for
electric power drag which timing range of constant power is not
more than 1:2, over-loading capacity is not more than 1.5 rated
torque. It also can be used for metal cutting machine tool, paper
making, print, textile, cement-making, etc. Generator can be used
for motive supply, illumination or other constant voltage supply.
Booster generator is also suitable for charge and floating charge
of large storage battery.
In order to adapt to adjusting voltage & speed in wide range
when constant torque and accurate speed control, D2 series has
developed derive structure of strong wind and it’s detector, which
electrical specification is wholly the same with D2. But when
D2machine is equipped with ride style fan or double fan and speed
indicating generator, it has compact structure and can run at a low
speed for a long time, to make the use of wide range of
adjustable-speed, accurate speed control.
To meet the requirement of timing when constant torque, D2 series
electrical machine can be made to independent excitation generator
with all kinds of excitation voltage to easily speed adjustment.
According to different excitation power source, excitation voltage
can be 110V, 220V, also can be other suitable voltage.
Furthermore, D2 series can be adapted to other special demand, and
in order to meet other special requirements. D2 series derive some
1. DT2 wide range of adjustable-speed motorthe range of adjust
magnetism and speed when the motor is running at the constant power
is 1:3 and 1:4. It is convenient for power supplying to constant
voltage network which needs wide range of speed adjustment. To
reduce the draught loss when running at a high speed, DT2 which
frame size is more than 7 commonlly adapt strong ventaging.
2. DT2 special voltage motor: motor which rated voltage is 180V,
340V and 440V are suitable for 1-phase and 3-phase controlled
silicon electrical source supply, motor which rated voltage is 275V
and 460V can be use for mine traction drive power source and other
situation which need special voltage & power source.
3. ZO2 enclosed type motor: fully-enclosed, suitable for special,
dustproof working environment.
4. According to special needs, D2 series can also derive with
compensate winding motor and generator. At this time, the overload
times can be increased to about 2.5 times of rated torque, and the
time of constant armature loop can be reduced, it’s suitable for
the situation which is large power servosystem or needs large
overload torque. Presently, No.8-11 frame have a part of
specifications, if needed, can be developed.
Above mentioned four kinds of special specifications, the overall
dimension, moment of inertia and weight are same as D2.

On the following conditions, this series motor can be used
(1) Altitude above sea level maximal 1,000m.
(2) Cooling air temperature maximal 40C.
Excluded the above basic voltage, running speed and this catalogue,
if you want other motor of special voltage and running
speed, you can also contact us. For example, high humidity can
humid torrid zone. The basic excitation type of motor is shunt
with a little series stable winding. The voltage-regulating
compounded excited excitation. (without series winding)
In order to meet different requirements, the series motor can be
made to all
kinds of independent excitation motor of different excitation
also can be made to series and compound excitation motor with
or compound percentage. Motor frame D2-1~8 use class B insulation
when the cooling air is not above +40C, the temperature rise of
winding is 80K
(resistance method). Motor frame 9~11stator use insulation cl
