What is an Explosion-proof Screen Protector? This is a Soft Film made of imported PET material. It has very good flexibility and can help you solve the problems of tilting, white edges, and not suitable for curved screens. Can closely fit the curved edge of the screen.
The PET Screen Protector is made of imported materials from Korea. It is equipped with a proprietary "self-healing" function that can automatically repair minor scratches on the film. Daily protection measures to prevent accidental knocks and drops. The screen strengthens the screen and reduces the chance of cracking. Broken tempered glass is no longer replaced frequently.
1. Edge coverage: The Explosion-proof Screen Protective Film is made of PET flexible material, which is very suitable for the screen of your device, and 100% provides excellent edge coverage, and there is no gap between the edges of the device
2. High-definition resolution: high-definition display, true display of the original screen color.
3. Original touch experience: The oleophobic coating surface of the screen protector can provide your phone with original texture and perfect touch screen response speed. The Soft Film also has oleophobicity and water resistance, which can prevent unnecessary fingerprints.
4. Self-repairing scratches: The Screen Protection Film with self-repairing function can automatically repair tiny scratches and bubbles within 24 hours.
5. Anti-seismic and explosion-proof: PET material has high strength, flexibility and elasticity, which can fully decompose the impact force and prevent the mobile phone from breaking
Servo drives, also known as servo controllers or servo amplifiers, are essential components used to regulate the operation of servo motors. They function similarly to frequency converters used with standard AC motors and are an integral part of a servo system. These devices are primarily employed in high-precision positioning systems where accuracy and control are critical. Servo motors can be controlled in three main modes—position, speed, and torque—to achieve precise motion control. As a result, servo drives have become a key technology in modern industrial automation.
The working principle of modern servo drivers is based on digital signal processors (DSPs) that enable advanced control algorithms, leading to greater digitalization, networking, and intelligence. The power section typically uses intelligent power modules (IPMs), which integrate driving circuits along with built-in protection features such as overvoltage, overcurrent, overheating, and undervoltage detection. IPMs also include soft-start circuits to minimize stress during startup. The power drive unit converts incoming AC power into DC using a three-phase full-bridge rectifier, and then inverts it back to AC using a three-phase sinusoidal PWM voltage to drive the motor. This process follows an AC-DC-AC conversion model, with the rectifier section commonly using a three-phase uncontrolled bridge circuit.
As the use of servo systems expands, the importance of proper usage, debugging, and maintenance of servo drives continues to grow. Many industrial control service providers are investing in in-depth research to improve performance and reliability. Servo drives play a crucial role in modern motion control, especially in applications like industrial robots and CNC machining centers. The design of AC servo drives often incorporates vector-based control strategies, including current, speed, and position closed-loop systems. The effectiveness of the speed control loop significantly influences the overall performance of the servo system.
**Basic Requirements of Servo Drive Systems**
1. **Wide Speed Range**: Servo drives must operate efficiently across a broad range of speeds.
2. **High Positioning Accuracy**: Precision is vital for accurate movement and control.
3. **High Rigidity and Stability**: The system should maintain rigidity and stability at high speeds.
4. **Fast Response and No Overshoot**: Quick response to commands without overshooting ensures smooth operation.
5. **Low-Speed Torque and Strong Overload Capacity**: The drive must deliver sufficient torque at low speeds and handle short-term overloads.
6. **High Reliability**: Servo systems must be robust, stable, and resistant to environmental factors like temperature, humidity, and vibration.
**Motor Requirements**
1. **Smooth Operation Across All Speeds**: The motor should run smoothly from the lowest to highest speeds with minimal torque fluctuation.
2. **Long-Term Overload Capability**: It must support heavy loads for extended periods.
3. **Low Moment of Inertia and High Stall Torque**: This allows for rapid acceleration and deceleration.
4. **Frequent Starts and Reversals**: The motor should be able to handle repeated start-stop cycles without failure.
**Key Features of Servo Drives**
1. The software of a servo driver includes main programs, interrupt services, and data exchange routines.
2. The main program initializes the system, controls interface signals, and sets up control module registers in the DSP.
3. After initialization, the main program waits for interrupts to adjust current and speed loops.
4. Initialization tasks involve setting up the DSP core, current and speed loop timing, PWM configuration, ADC setup, QEP initialization, and more.
5. The PWM interrupt program samples motor currents, calculates rotor orientation angles, and generates control signals.
6. The power protection interrupt detects faults in the IPM and triggers necessary actions.
7. Encoder zero-pulse capture ensures accurate feedback for vector control.
8. Data exchange programs manage communication with the host, parameter storage, and display functions.
