Facebook's first financial report after listing: mobile active users increase
A Dc Motor is any of a class of rotary electrical
machines that converts direct current electrical energy into mechanical energy.
The most common types rely on the forces produced by magnetic fields. Nearly
all types of DC motors have some internal mechanism, either electromechanical
or electronic, to periodically change the direction of current flow in part of
the motor.
DC motors were the first type widely used, since they
could be powered from existing direct-current lighting power distribution
systems. A 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 DC motors 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 DC motors are used in
propulsion of electric vehicles, elevator and hoists, or in drives for steel
rolling mills.
Dc motor areas of application: smart home field, robotics, precision medical equipment industry, automotive drive field, electronic products and personal care equipment
Application of the product:
Features: high torque, low noise, small volume, light weight, easy to use, running
constant speed, etc., can also be matched with various gearboxes to change the
output speed and torque.
Features: small volume, fast speed, stable performance, low price, good speed regulation.
Method
of use: the best stable in horizontal plane, installed on the dc motor output
shaft parts, cannot use a hammer to knock, knock prone to press into the dc
motor drive, may cause damage to internal components, and cannot be used in the
case of blocked.
Operating temperature range:
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 geared 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:
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:
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.

Facebook's advertising revenue for the second quarter ended June 30 was $992 million, an increase of 28%. The number of monthly active users in the second quarter was 955 million. Although the number of active users per month increased by 29% year-on-year and was in line with analysts' consensus expectations, the daily number of active users was an average of 552 million, which exceeded analysts' expectations. The number of active users per day increased by 32% year-over-year, exceeding analysts' average forecast of 19%.
The largest year-on-year increase was mobile active users. The number of mobile active users in the second quarter was 543 million, a year-on-year increase of 67%.
According to Facebook’s financial report, Facebook’s actual net loss of US$157 million was calculated by calculating the quarterly earnings per share of $0.08 per share before 2011. Facebook’s capital expenditure in the second quarter was US$ 413 million, a year-on-year increase of 213%. According to GAAP statistics, Facebook’s second quarter operating loss was US$743 million. In the same period last year, Facebook’s operating profit according to GAAP was US$407 million.
