3. Product Features
The motor adopts medium inertia rotor design, which has good load adaptability and anti-interference ability, and can maintain stable operation under fluctuating load and frequent speed regulation conditions. Built-in high-resolution absolute encoder realizes high-precision closed-loop speed and position feedback, ensuring accurate positioning and repeat positioning accuracy. Optimized electromagnetic winding design effectively reduces cogging torque, making the motor run smoothly at low speed and high speed without crawling and jitter phenomenon. Fully sealed integral shell and waterproof connector structure meet IP67 protection standard, which can effectively prevent dust intrusion and liquid splashing immersion, suitable for harsh workshop working conditions. The motor has high mechanical rigidity and reinforced bearing structure, with strong vibration resistance and long service life. High-efficiency magnetic circuit design reduces operating heat generation and energy consumption. The standard mounting size and electrical interface are completely compatible with the original FANUC servo amplifier, supporting direct replacement without complicated parameter modification.
4. Installation Instructions
Before installation and maintenance, please completely cut off the power supply of the equipment and servo system to ensure operation safety. Check the motor appearance, flange surface, output shaft and keyway for damage, deformation, rust and foreign matter adhesion. Align the motor flange with the mechanical mounting surface, use standard bolts for fixing, and tighten evenly to ensure the flatness of the mounting surface and the concentricity of installation. When installing coupling and transmission parts, strictly ensure the coaxiality between motor shaft and load shaft, avoid eccentric installation, so as to prevent vibration, noise and abnormal wear during operation. Connect the motor power cable and encoder cable in strict accordance with the official wiring specification and pin definition. Arrange the cables reasonably during wiring, avoid sharp bending, excessive stretching and heavy extrusion, and do not lay cables cross with high-voltage lines. Fix the cables with cable ties to prevent long-term vibration from causing cable loosening and damage. After installation, recheck all mechanical fastening bolts and wiring connections to ensure firm installation and correct wiring. After confirming no error, power on the system, complete servo initialization and origin calibration, and perform no-load test operation to check whether the motor runs smoothly without abnormal noise and vibration.
5. Operation Precautions
Do not make the motor operate beyond the rated voltage, rated speed and rated load range, so as to avoid motor overheating, magnetic demagnetization and winding burnout. Avoid long-term frequent forward and reverse inching operation, reduce overcurrent impact and thermal load of the motor. Do not use the motor in explosive gas, corrosive gas, conductive dust and direct water spraying environment, so as not to damage the motor sealing structure and internal components. The motor and equipment must be reliably grounded to prevent electric leakage accidents and electromagnetic interference from affecting positioning accuracy. Do not disassemble the motor shell, internal encoder and rotor structure without professional permission, otherwise it will cause permanent damage and void the warranty. If abnormal noise, obvious vibration, shell overheating and servo system alarm occur during operation, please stop running immediately and cut off the power supply for inspection. Do not apply heavy impact and long-term axial pressure to the motor output shaft, so as to prevent shaft deformation and internal encoder precision damage. Regularly check the sealing performance of the connector and waterproof rubber ring to maintain the IP67 protection level for a long time.
6. Maintenance and Storage
Regularly clean the dust and oil stains on the motor surface, keep the motor heat dissipation surface clean and unobstructed, and ensure natural heat dissipation effect. Regularly check the motor mounting bolts, coupling connection parts and cable terminals for looseness, and tighten them in time if any looseness is found. The motor bearing is filled with lubricating grease at the factory, which can be used for a long time under normal working conditions. If abnormal noise and vibration occur during operation, the bearing should be inspected and replaced in time. When storing the motor, place it in a dry, ventilated and dust-free indoor environment without corrosive gas. The storage temperature is controlled between 5℃ and 35℃, and the relative humidity is not more than 85% to avoid condensation. Avoid collision, extrusion, falling and long-term heavy pressure on the motor during handling and storage. It is recommended to keep the original packaging for storage. The shelf life of the motor under standard storage conditions and original sealed packaging is 12 months.
