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

,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.

Ye Guoguang, the marketing and sales director of Guangdong Deli Optoelectronics, said frankly that half of the mainland PSS market is from the processing and production of epitaxial chip manufacturers, and half of them are from sapphire manufacturers in Taiwan, while mainland sapphire manufacturers have missed.
At present, mainland sapphire manufacturers mainly produce flat sapphire substrates, and rarely produce equipment to process PSS. PSS gross margin is high, why mainland sapphire manufacturers turn a blind eye to this market, and Taiwan sapphire manufacturers and LED chip manufacturers are so keen?
There is a big technical risk for mainland sapphire manufacturers to do PSS. If the sapphire manufacturer does not produce high brightness, the manufacturing cost of PSS substrate is higher. According to an industry source, PSS belongs to the semiconductor category, and sapphire belongs to the field of silicon crystal. The technical processes of the two are very different. LED epitaxial chip manufacturers are originally in the semiconductor category, and they also do PSS in the original semiconductor equipment, and the technical difficulty and production cost are relatively small.
At present, domestic chip companies such as Sanan Optoelectronics (600703.SZ) and Dehao Runda (002005.SZ) are already developing and producing PSS, and companies such as Xiangneng Hualei and Huacan Optoelectronics (300323.SZ) are also trial production. .
For the phenomenon that the extension manufacturers do PSS, it is possible for Ye Guoguang to minimize the cost. “The price of a 2-inch per-sheet for a mid- to high-end PSS substrate is around $14, compared to $7 for a plain flat sapphire substrate. If the cost of an existing PSS for an extension manufacturer is only $2 per piece, calculate it compared to outsourcing. Companies can save $4 to $5 in costs."
Ye Guoguang believes that subject to the dual benefits of technology and cost, there will inevitably be more chip makers making PSS in the future. Sapphire manufacturers will take the initiative to abandon this market and seek a way out for their flat sapphire market.
However, in the Taiwan market where the division of labor is clear, the industrial division of labor for companies dealing with PSS is completely different.
"New Industry" has learned that almost all sapphire manufacturers in Taiwan have been vigorously promoting PSS substrates, such as Zhaoyuan, Xinjing Diamond and Ruijie Technology. Taiwanese chip makers have not made PSS, but have purchased PSS on a large scale from sapphire manufacturers. Previously, Jingyuan Optoelectronics disclosed that it has already included two PSS production lines for each of the two sapphire manufacturers, Zhaoyuan and Ruijie.
Benefiting from the continuous growth of PSS demand, the performance of Taiwan Ruijie Technology, which focuses on PSS, has maintained rapid growth. In the first half of 2013, Ruijie Technology achieved a revenue of NT$120 million, a year-on-year increase of 46%.
At present, some sapphire manufacturers in mainland China, such as Yunnan Blue Crystal, are also looking for Ruijie Technology to do PSS OEM.
Mainland sapphire manufacturers seem to be giving up the PSS market.

Mainland sapphire manufacturers may give up the PSS market
[Text / "New Industry" reporter Tang Guirong] Due to high luminous efficiency, this year's sapphire graphics substrate (PSS) has been widely used. PSS is machined from flat sapphire and used as a high-brightness LED chip substrate. However, Chinese sapphire manufacturers seem to be not flustered by PSS, and epitaxial chip makers seem to have a soft spot.
