Electric dc motors were the
first type widely used, since they could be powered from existing
direct-current lighting power distribution systems. A electric Dc Motor's speed can be controlled over a wide range, using either a variable supply
voltage or by changing the strength of current in its field windings. Small electric dc motor are used in tools, toys, and appliances. The universal motor
can operate on direct current but is a lightweight motor used for portable
power tools and appliances. Larger electric dc motor are used
in propulsion of electric vehicles, elevator and hoists, or in drives for steel
rolling mills.
Areas of application: the electric dc motor rotor part of the armature iron core, armature, commutator, such as equipment, electric dc motor is suitable for most electronic products, such as electric screwdriver, laser, smart home, gas valve, etc
Applications:
Method of use: the best stable in
horizontal plane, installed on theelectric dc motor output
shaft parts, cannot use a hammer to knock, knock prone to press into the electric
dc motor drive, may cause damage to internal components, and cannot be
used in the case of blocked.
Operating
temperature range:
Electric dc motor should be used at a temperature of -10~60℃.
The figures stated
in the catalog specifications are based on use at ordinary room
temperature catalog specifications re based on use at ordinary room
temperature (approximately20~25℃.
If a electric dc motor is used outside the prescribed temperature range,the grease on the gearhead
area will become unable to function normally and the motor will become unable
to start.Depending on the temperature conditions ,it may be possible to deal
with them by changing the grease of the motor's parts.Please feel free to
consult with us about this.
Storage
temperature range:
Electric dc motor should be stored ta a temperature of -15~65℃.
In case of storage
outside this range,the grease on the gearhead area will become unable to
function normally and the motor will become unable to start.
Service life:
The longevity of
geared motors is greatly affected by the load conditions , the mode of
operation,the environment of use ,etc.Therefore,it is necessary to check the
conditions under which the product will actually be used .The following
conditions will have a negative effect on longevity.Please consult with us
should any of them apply.
â—Use with a load
that exceeds the rated torque
â—Frequent starting
â—Momentary reversals
of turning direction
â—Impact loads
â—Long-term
continuous operation
â—Forced turning
using the output shaft
â—Use in which the
permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive
,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage
that is nonstandard as regards the rated voltage
â—Use outside the
prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with
us about these or any other conditions of use that may apply,so that we can be
sure that you select the most appropriate model.

(2) Whether the post-process package is reasonable will affect the life of the LED. Whether the post-process package of the LED is reasonable will affect the life of the LED. At present, the world's major companies such as Cree, Lumilends, Nichia and other high-level LED packages have patent protection. These companies have higher post-process packaging requirements and their LED life is guaranteed. However, the LED post-process package of most enterprises has more imitations, and it can be seen from the appearance. The process structure and process quality are poor, which seriously affects the life of the LED.
(3) Lighting design is the key issue <br> <br> reasonably affect the life of LED lamps lighting design in addition to meeting other indicators lamps, a key issue is the heat generated by the LED lights up when you want comes out. Using high-quality LED originals from Cree and other companies on different luminaires, the LED life can be several times or even several times. For example, the integrated light source luminaires currently sold in the market (single 30 W, 50 W, 100 W), the light source and the heat sink channel contact parts of these products are not well cooled, resulting in some products causing light after lighting for 1-3 months. More than 50% decay, some products use a small power tube of about 0.07 W, because there is no reasonable heat dissipation mechanism, resulting in very fast light decay. These products are low in technical content, low in cost and short in life.
(4) lighting power supply is essential <br> <br> lamps use is reasonable will affect its lifespan for LED life. Because the LED is a current-driven device, if the power supply current fluctuates greatly, or the power spike has a high frequency, it will affect the life of the LED light source. The life of the power supply itself depends mainly on whether the power supply design is reasonable. Under the premise of reasonable power supply design, the life of the power supply depends on the life of the components. 
What is the impact of the life of LED lamps
(1) is determined by mass LED die life <br> <br> first condition of the LED manufacturing process, contamination of other impurity ions, lattice defects and other processes will affect their life, so a high-quality LED tube The core is the primary condition.
