Detailed explanation of core technical parameters

1. Power performance parameters

-Rated power: 0.2kW (200W), belonging to the category of small servo motors, suitable for precision drive scenarios with medium and low loads, such as small robotic arm joint drive, precision detection platform feed, etc.

-Speed characteristics: rated speed of 3000r/min, speed tolerance of ± 10%, ensuring speed stability under rated operating conditions; The maximum no-load speed can adapt to system requirements for precise control, and with efficient driving algorithms, it can achieve smooth switching and fast response of speed.

-Torque performance: rated torque 0.64N · m, instantaneous maximum torque 1.92N · m, with 3 times overload capacity. This feature enables it to maintain stable operation in scenarios of sudden load changes, such as device startup and emergency positioning, avoiding positioning deviations or system shutdowns caused by load fluctuations.

2. Electrical characteristic parameters

-Power specification: Using single-phase AC200V power supply, the voltage fluctuation adaptability range is -15% to+10%, which can adapt to voltage fluctuations in different regions of the power grid and reduce the impact of voltage instability on motor operation.

-Encoder configuration: Standard 13 bit high-resolution relative value encoder, capable of outputting 8192 pulse signals per revolution. This encoder provides core feedback guarantee for the precise positioning of the servo system, enabling the control accuracy of the motor to reach ± 0.01 ° within the full speed range, which can meet the high positioning accuracy requirements of scenarios such as semiconductor packaging and optical detection. Some upgraded versions can support 20 bit serial encoders, further improving resolution and control accuracy.

-Insulation and withstand voltage performance: The insulation resistance is ≥ 10M Ω under DC500V testing conditions, and the insulation withstand voltage is AC1500V for 1 minute (200V level). The main circuit and control circuit are designed to be isolated, effectively avoiding interference between control signals and power signals, while improving the electrical safety and anti-interference ability of the motor.

3. Physical and installation parameters

-Structural dimensions: Adopting a compact design, the specific dimensions are 120x100x80mm (length x width x height), with a weight of only 3.5kg, making it easy to integrate into space limited equipment such as small automated assembly machines, medical instruments, etc.

-Shaft end design: The standard configuration is a straight shaft without keyway, and a version with oil seal and holding brake (DC90V) can be selected according to actual application needs. The brake can achieve positioning and holding after the motor is powered off, suitable for vertical loads or emergency braking scenarios.

-Installation method: Adopting flange installation, standardized installation interface, convenient for precise docking with various mechanical structures, and reducing the difficulty of equipment integration. The default rotation direction is counterclockwise (CCW) when viewed from the load side under the forward rotation command, and the steering can be adjusted through system parameters.

Key functional features and technological advantages

1. High precision closed-loop control technology

The motor adopts a brushless permanent magnet structure, combined with a high-resolution encoder to achieve full closed-loop control. Its working principle is based on the generation of a rotating magnetic field by the stator winding, which interacts with the permanent magnet rotor to generate torque. At the same time, the encoder collects real-time rotor position information and feeds it back to the servo driver. The driver decomposes the stator current into magnetic field component (Id) and torque component (Iq) through vector control algorithm (FOC), and accurately regulates them respectively, achieving high-precision control of motor speed and position. Compared to traditional control methods, vector control technology significantly improves the dynamic response speed and steady-state control accuracy of motors, effectively suppresses speed fluctuations, and ensures smoother operation.

2. Intelligent automatic tuning function

Equipped with advanced automatic tuning function, it can automatically detect and adapt the characteristic parameters of mechanical loads (such as inertia, damping, etc.), and optimize the control parameters of the servo system (such as gain, integration time, etc.) to achieve the best matching state between the servo system and the mechanical system. This feature significantly reduces the difficulty of system debugging and reduces debugging time. Even non professional operators can quickly complete system setup and optimization, while improving the overall stability of the system and avoiding oscillation or slow response caused by parameter mismatch.

3. Comprehensive diagnostic and maintenance functions

-Fault diagnosis function: It has comprehensive fault detection and alarm functions, which can monitor the encoder status, power supply voltage, overload situation, overheating and other abnormal working conditions in real time, and output corresponding alarm codes (such as encoder fault corresponding alarm code A.84) through servo drives, making it easy for operators to quickly locate the cause of the fault.

-Alarm tracking memory: supports the tracking and memory of alarm information, can record the operating parameters before and after the occurrence of faults, and provide detailed data support for fault diagnosis. The isolation design between the main circuit and the control circuit enables maintenance to be carried out by simply turning off the power supply of the main circuit in case of a fault, ensuring the safety of maintenance personnel and simplifying the maintenance process.

-Convenient wiring and debugging: Adopting a fully plug-in terminal block, the wiring is standardized and convenient, reducing the risk of wiring errors; Supports RS485/Modbus communication protocol, enabling efficient data exchange with the upper control system, facilitating centralized monitoring and parameter adjustment of the system. In addition, advanced functions such as parameter backup and waveform recording can be achieved through the Yaskawa Mechatrolink II debugging software, further improving debugging and maintenance efficiency.

4. Mechanical resonance suppression ability

Built in mechanical resonance suppression algorithm can automatically detect the resonance frequency of mechanical systems and suppress resonance by adjusting control parameters, effectively reducing the impact of mechanical vibration on system operation. This function is particularly important in vibration sensitive scenarios such as precision machining and optical inspection, which can avoid the decrease in machining accuracy or increase in detection errors caused by vibration, and improve the machining/detection quality of the equipment.

Environmental adaptability and protective performance

1. Protection level and anti pollution design

The protection level reaches IP65 (IP52 at the shaft end), which means that the motor body can completely prevent dust from entering and can withstand low-pressure water spray in any direction. The IP52 level at the shaft end can prevent harmful dust accumulation and vertical dripping from entering. Simultaneously adopting oil resistant design, it can adapt to the common oil pollution environment in industrial sites, expand its application scope, and can be safely applied to scenarios with high oil pollution such as machine tools and packaging machinery.

2. Wide temperature and humidity range and resistance to shock and vibration

-Temperature adaptability: The working environment temperature range is 0-40 ℃ (without freezing), and the storage temperature range is -15-70 ℃, which can adapt to the temperature conditions of most industrial sites and avoid motor performance degradation or damage caused by high or low temperature.

-Humidity adaptability: The working environment has a humidity of 20-80% RH (no condensation), effectively preventing electrical component short circuits or corrosion problems caused by moisture condensation.

-Anti impact and vibration capability: The anti impact level reaches 5G (10-55Hz), and the vibration level is V15. It can withstand the common impact and vibration interference in industrial sites, ensuring stable operation under harsh working conditions and extending the service life of the motor.

3. Altitude adaptability

Suitable for use at altitudes ≤ 1000m. When used in ultra-high altitude environments (exceeding 1000m), the motor performance and safety should be ensured through derating operation to avoid poor heat dissipation or insulation performance due to thin air.

Typical application scenarios

1. Precise positioning system
