Chinese Consumers Use Mobile Devices Will Surpass TV Firstly This Year

Sina Technology News Beijing time in the late April 19th news, research company eMarketer today issued a report that this year Chinese adults will use mobile devices for the first time to watch TV time. The report expects Chinese adults to spend 2 hours and 39 minutes on mobile devices every day this year, up 11.1% from last year, accounting for 41.6% of their daily media consumption. By contrast, the time they watch TV every day is estimated to be 2 hours and 32 minutes, down 2% from last year, accounting for 39.8% of their daily media consumption. Among them, watching online video is the main reason for Chinese consumers to spend more time in mobile devices. EMarketer expects Chinese adult consumers to watch online video at a time of 58 minutes this year, up nearly 26% year on year, accounting for more than 25% of their digital content consumption. By 2020, the proportion will increase to about 33%. The popularity of online video is largely due to market innovation, especially from Baidu, Alibaba and Tencent's video platforms. In addition, the short video has also played a great role in promoting. EMarketer analyst Selling Shum Shum said: "the time for Chinese consumers to watch TV will accelerate and decline, especially in the first tier cities." (Shelleen) At the same time, they are increasingly watching online videos through video platforms, because they are rich in content and can also be online on demand. With the popularity of smart phones and the improvement of network speed, people can watch and publish videos while doing other daily activities. Shum added: "short video has experienced explosive growth in the past year in addition to the long video of TV plays. In the past year, a lot of investments have been made in short video applications such as watermelon video and fast hands. In addition, e-commerce and news aggregation applications are also using short videos to enhance user interaction. (Li Ming)

Servo Concept

The steering gear first appeared in the movement of aeromodelling. In the aviation model, the flight attitude of the aircraft is achieved by adjusting the engine and each control rudder. For a simple four-way airplane, there are several places on the plane that need to be controlled: 1. The amount of engine air intake to control the engine's pull (or thrust); 2. Aileron rudder (installed on the trailing edge of the aircraft wing) to control the roll motion of the aircraft; 3. Horizontal rudder surface, used to control the aircraft's pitch angle; 4. Vertical rudder surface, used to control the yaw angle of the aircraft; The remote control has four channels, corresponding to four servos respectively, and the steering gear drives the rotation of the rudder surface through the connecting rod and other transmission elements, thereby changing the movement state of the aircraft. The servo is thus named: Servo motors that control the rudder. Not only in the model aircraft, but also in other model movements can see its application: used to control the rudder on the ship model, used to turn the car model and so on. It can be seen that the servo can be used to achieve any operational action.

Digital Servo

The digital servo is different from the traditional analog servo. The analog steering gear needs to continuously send a PWM signal to keep it in the specified position or let it rotate at a certain speed. The digital steering gear only needs to send a PWM once. The signal can stay in the specified position. Therefore, the appearance of digital steering gear to achieve the realization of 48 servo controller. According to the steering angle of the servo divided 180 degrees servo and 360 degree servo. The 180 degree servo can only move between 0 degrees and 180 degrees. If the servo exceeds this range, the servo will have an over-range fault. If the gear is broken, the gear will be damaged or the servo motor inside the servo will be damaged. The 360-degree servo rotates in a manner similar to a normal motor, and it can rotate continuously. However, we can only control the direction and speed of its rotation and cannot adjust the angle of rotation.

New Small Servo Motors For Short-stroke Movements At Lightning Speed

Travel speeds of up to 900mm/s are now a reality thanks to the new “short stroke dynamics” variant of WITTENSTEIN cyber motor’s cyber dynamic line. This new option is available for all four sizes of the industrial grade small servo motors with integrated screw. Together with the servo controllers in the WITTENSTEIN cyber motor simco drive series, it can be configured as a complete small servo axis to meet even the highest dynamics requirements of short-stroke applications. It is typically used for positioning, joining, bending, gripping and dispensing in reshaping and handling applications, the semiconductor industry, packaging machinery or assembly automation. The 100 percent stainless steel model with IP65 protection also opens up numerous interesting applications for all fully integrated linear actuators in the cyber dynamic line in the wet areas of manufacturing, packing, filling and bottling plants for food and beverage products. Servo actuators convince with process quality and reliability The complete series of small servo motors with integrated screw is designed for use in highly dynamic positioning axes of machines or for installation where space is restricted. The new variant has been specifically optimised for rapid movements of up to 50mm by modifying the ball screw drive. With a maximum travel speed of 900mm/s, the “short stroke dynamics” version of the cyber dynamic line is a good alternative to pneumatic cylinders, even in the most highly dynamic applications, so that better, more reliable and more economically efficient machining processes can now be achieved. Unlike their pneumatic equivalent, the small servo motors are not only easy to connect to a higher-level controller. They also allow precise position control – without any retooling on the machine in case of format changes. Another advantage of this servo technology is that it is leakproof and far more energy efficient in normal operation – after all, compressed air is not only expensive to produce but a significant share of it is lost. Finally, the small servo motor with integrated screw are virtually maintenance-free and simultaneously quieter – two further benefits compared to pneumatics. Small servo motors excite with industry grade design and compactness All variants of the small servo motors with integrated screw enable highly optimised mounting solutions in the sizes with an outer diameter of 17, 22, 32 or 40mm. The servo motor, spindle drive, linear guide rail and encoder system were designed by WITTENSTEIN cyber motor as a closed, highly integrated and ready-to-install unit – with the result that the moment of inertia is much lower than is possible, for instance, if the screw is simply attached to the servo motor. The strictly industry grade design was also a top priority. The complete drive is accommodated in a robust stainless steel housing with IP54 protection and can be mounted in any position. Small servo drive systems score with connectivity and risk-free commissioning The new small servo motors with integrated screw can be configured with simco drive servo controllers to form high-performance small servo axes. Multiple connectivity options are available for these solutions, which can be integrated in a higher-level controller via CanOpen, EtherCAT, Profinet RT/IRT, EtherNet/IP and now also SERCOS. In spite of this, this single-source system solution entails absolutely no interface risks.

Common Industrial Applications For Servo Motors

Servo motors are small and efficient but critical for use in applications requiring precise position control. The servo motor is controlled by a signal (data) better known as a pulse-width modulator (PWM). Here are several of the more common servo motor applications in use today. Robotics: A servo motor at every "joint" of a robot is used to actuate movements, giving the robot arm its precise angle. Conveyor Belts: Servo motors move, stop, and start conveyor belts carrying product along to various stages, for example, in product packaging/bottling, and labeling. Camera Auto Focus: A highly precise servo motor built into the camera corrects a camera's lens to sharpen out-of-focus images. Robotic Vehicle: Commonly used in military applications and bomb detonation, servo motors control the wheels of the robotic vehicle, generating enough torque to move, stop, and start the vehicle smoothly as well as control its speed. Solar Tracking System: Servo motors adjust the angle of solar panels throughout the day so that each panel continues to face the sun, harnessing maximum energy from sunup to sundown. Metal Cutting & Metal Forming Machines: Servo motors provide precise motion control for milling machines, lathes, grinding, centering, punching, pressing, and bending in metal fabrication for such items as jar lids to automotive wheels. Antenna Positioning: Servo motors are used on both the azimuth and elevation drive axis of antennas and telescopes such as those used by the National Radio Astronomy Observatory (NRAO). Woodworking/CNC: Servo motors control woodturning mechanisms (lathes) that shape table legs and stair spindles, for example, as well as augering and drilling the holes necessary for assembling those products later in the process. Textiles: Servo motors control industrial spinning and weaving machines, looms, and knitting machines that produce textiles such as carpeting and fabrics as well as wearable items such as socks, caps, gloves, and mittens. Printing Presses/Printers: Servo motors stop and start the print heads precisely on the page as well as move paper along to print multiple rows of text or graphics in exact lines, whether it's a newspaper, a magazine, or an annual report. Automatic Door Openers: Supermarkets and hospital entrances are prime examples of automated door openers controlled by servo motors, whether the signal to open is via push plate beside the door for handicapped access or by radio transmitter positioned overhead. The world would be a much different place without servo motors. Whether they're used in industrial manufacturing or in commercial applications, they make our lives better, easier, and in many cases provide us with more affordable products.

Why Do We Combine A Servo Motor With A Gearbox

Why a gearbox is essential when using a servo motor Almost every robot as we know it is equipped with servo technology, which enables them to move faster, more accurately and without interruption. Gearboxes are needed to translate the high speed of the sevor motors in a controlled movement of the arm, for example to pick a product. Without a gearbox, the mass and velocity of this arm will demand the behaviour of motor and it will literally overshoot the target.
