Energy-saving techniques
The sewing machine reduces power consumption with its advanced energy-saving techniques.
The latest compact-size servomotor has been adopted.
The DDL-9000B has adopted the latest compact-size servomotor as its driving
source. This latest compact-size servomotor is an energy-saving, highly efficient
motor which is able to run under a high torque and has a broader range of speed.
In addition, the servomotor is installed with a direct-drive system to transmit
the motor power directly to the sewing machine, thereby achieving improved
power-consumption saving, quicker response, quicker startup, increased accuracy
of the stop position and stronger material penetrating force of the needle.
The new model control box, which energy-saving mode is provided.
The new model control box SC-920, which consists of an energy-saving mode, has
been developed. This control box is the first one which provides an energy-saving
mode for the sewing machine. The power consumption during standby, when the
motor is at rest, is reduced by approximately 20%.
In addition, abundantly incorporated state-of-the-art energy-saving features such as
a compact-in-size solenoid for the auto-lifter (optional) allow the DDL-9000B to
reduce power consumption, to increase productivity and to be friendly to the
environment.
Comparison of power consumption
When the sewing machine availability factor is 25%, the DDL-9000B reduces
power consumption by 70% or more as compared with the conventional model
incorporating a V-belt type electronic stop motor, by 20% or more as compared
with the conventional model incorporating a V-belt type servomotor, or by 15%
as compared with its predecessor model (DDL-9000A).

Dry technology
The advanced dry technology helps prevent oil stains on the material being sewn. The main source of oil stains is the frame.
The semi-dry head type sewing machine comes with a frame which does not need lubrication. The fully-dry head type sewing
machine is an even further evolved dry-head type which comes with a frame and a hook section which do not need lubrication.
The needle bar mechanism is finished with a special surface treatment (DLC,
Diamond Like Carbon Coating) and uses JUKI's unique special grease for
lubrication. Grease-filled bearings have been adopted for the sections requiring
bearings.
The frame mechanism of the sewing machine demonstrates superb durability
even with no oil. Oil stains on the material being sewn are reduced. As a result
the frequency of stain removal work or re-sewing work is dramatically reduced,
thereby improving the finished quality of the product.

Design for achieving silent operation
One of the eternal challenges of a sewing plant is the improvement of the work environment.
One of the factors to be improved is noise within the plant. The DDL-9000B 1-needle lockstitch
machine is the sewing machine which is used most frequently in the sewing plant. For this
reason, the noise generating mechanisms have been attuned to eliminate any harsh noise.
The major sources of noise are the one-touch type reverse feed device, the wiper and the
auto-lifter, which have been designed aiming at the reduction of noise.
The resulting mechanisms' operating noise is reduced, thus helping reduce operator fatigue.
One-touch type reverse feed device
Power consumption is substantially decreased.
