Our first contact with Fanuc servo motor is more than ten years ago, a customer's CNC lathe always appear machining accuracy drift. At first, we suspected that the tool clamping is not stable, changed a few sets or not. Finally, an old maintenance master squatted at the machine, listened to the motor running sound, said: "not the knife, is the servo motor feedback problem.” Remove a look, the encoder in the accumulation of metal dust, resulting in position feedback jump. After cleaning it up, the machine immediately returned to accuracy. This incident made me realize for the first time, Fanuc servo motor is not an ordinary motor, it is the entire precision motion system "brain and muscle” combination.
Its Core Task
The most important function of
Fanuc servo motor is to make the machine move accurately, quickly and steadily. It and the driver, encoder form a closed-loop control system, real-time from the CNC or PLC to receive instructions - to turn how many degrees, how fast, how strong - and then immediately executed, and at any time according to the feedback fine-tuning.
And stepper motor kind of "according to the grid go” way different, servo motor is "always correct the route”. As if you drive a car on the highway, stepper motors are like cruising in a fixed direction, while servo motors are like an old driver holding the steering wheel all the time, fixing the direction as soon as the road conditions change.
In the industrial field, this ability has several benefits:
* High accuracy: Whether doing CNC processing of precision molds, or assembly robots on the screws, can do millimeters or even micron-level positioning.
* Fast response: some actions on the production line only give you a few hundred milliseconds of reaction time, Fanuc servo motors do not drag at all.
* Strong adaptability: the load suddenly becomes large, such as the robot grasping the parts heavier than expected, it can also immediately compensate, will not shake, no stop.
* Dynamic stability: high-speed movement is still stable, like laser cutting, 3D printing, such as the requirements of the side of the fast and stable scene, it is more veteran.
Where It Has Made Its Mark
The applications of Fanuc servo motors cover almost the entire industrial automation circle:
* CNC machine tools: control the axis movement of the tool or workpiece, so that processing is both fast and accurate.
* Industrial robots: welding, handling, painting, assembly, smooth and precise movements.
* Automated production line: belt machine, sorting robot, marking machine can not be separated from its precise control.
* Laser cutting/3D printing: ensure the stability and precision of the cutting trajectory and printing layer.
The Secret Weapon of Fanuc Servo System
What makes a Fanuc servo motor so powerful cannot be separated from the partners around it:
* Servo drive: like its commander, responsible for regulating speed, position and torque.
* High-precision encoder: its eyes, real-time reporting of rotation, so that the system is always corrected.
* Closed-loop control system: ensures that every movement is monitored in real time and corrected instantly.
Advantages Known to Those Who Have Used It
* Power saving and high efficiency: power output is adjusted on demand without wasting a trace of energy.
* High precision and high stability: it can hold even aerospace-grade precision parts processing.
* Resistant to "tossing”: it is still as stable as an old dog in places with large load changes and harsh working conditions.
The Most Common Problems in the Field
* Overheating: high ambient temperature, heavy load or poor heat dissipation may make the motor fever, long time this is very hurt.
* Electrical interference: plant welding machines, frequency converter more times, be careful of interference signals, let it use shielded wires and filters will be much better.
* Mechanical wear: Wear of bearings and gears will affect the performance. Regular inspection and replacement of parts will add years to the life of the motor.
Maintenance Experience
* Regular inspection: appearance, wiring, encoder status should be looked at.
* Cleaning and lubrication: Especially for equipment that has been operating under high load for a long period of time, accumulation of dust and lack of oil are invisible killers.
* Make good use of the diagnostic function: Fanuc's servo system comes with alarms and fault codes, so if something goes wrong, first see what it suggests, and then start to troubleshoot.
* Find reliable technical support: Fanuc has a technical network around the world, do not delay, repair is not a motor thing.
Conclusion
In this line of industrial automation, Fanuc servo motor is the kind of "usually do not show, a bad let you know how important it is” guy. Its high precision, high response, high stability, so that it has become the heart of the global manufacturing industry. Whether you want to build a new production line, or to the old equipment to change the heart, choose Fanuc servo motor, basically equal to the equipment on a strong, smart and durable "heart”.
