This product adopts permanent magnet synchronous servo motor control principle. The servo drive outputs adjustable frequency and voltage three-phase AC to the stator winding to generate a rotating magnetic field, which drives the permanent magnet rotor to rotate and output mechanical torque. The built-in absolute encoder collects the real-time position, speed and rotation angle of the rotor, and feeds back data to the upper servo drive to form a full closed-loop control. The control system adjusts the output electrical parameters in real time according to the operating commands, so as to complete high-precision speed regulation, positioning and torque output. The temperature sensor monitors the internal temperature in real time and triggers protection action when over temperature occurs.

- Excellent dynamic performance, suitable for high-frequency reciprocating motion
- High structural rigidity, strong resistance to vibration and impact
- Good heat dissipation performance, supporting long-time continuous heavy-load operation
- Standard industrial interface, easy system integration and after-sales maintenance
Machine tool equipment, automated production lines, logistics handling machinery, lifting positioning equipment, rubber and plastic machinery, metal processing equipment, intelligent storage equipment
- Use standard flange for fixed installation, ensure the mounting base has sufficient rigidity
- Strictly control the coaxiality between motor shaft and load shaft to prevent additional shear force
- Install wiring in accordance with the standard phase sequence, and do not mix power line and signal line
- The surrounding environment shall be kept ventilated, and heat accumulation is prohibited
- For long-distance transmission, use shielded cables for encoder signal lines
- Long-term operation under rated load is allowed; continuous overload operation is prohibited
- Regularly inspect the sealing performance of the motor and the wear of the shaft keyway
- Avoid working in environments with high temperature, high humidity and corrosive gas for a long time
- Do not disassemble the motor body and internal encoder privately
- Cut off the power supply completely before maintenance and wiring operation
- If abnormal vibration or noise occurs during operation, stop the machine for inspection immediately
