What Is Servo Motor?
A servomotor (or servo motor or simply servo (to be differentiated from servomechanism, which may also be called a servo)) is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration in a mechanical system. It consists of a suitable motor coupled to a sensor for position feedback.
Accuracy: Realize the closed-loop control of position, speed and torque; overcome the problem of stepping motor out of step;
Speed: highHigh-speedformance is good, generally the rated speed can reach 2000~3000 rpm;
Adaptability: Strong anti-overload ability, able to withstand a load three times the rated torque, especially suitable for occasions with instantaneous load fluctuations and requirements for quick start;
Stable: Low-speed operation is stable, and there will be no stepping phenomenon similar to that of stepping motors during low-speed operation. Suitable for occasions with high-speed response requirements;
Timeliness: The dynamic response time of motor acceleration and deceleration is short, generally within tens of milliseconds;
Comfort: Heat and noise are significantly reduced.
Dc servo motor
The motor which is used as a DC servo motor generally have a separate DC source in the field of winding & armature winding. The control can be archived either by controlling the armature current or field current.Based on the applications the control should be applied to the DC servo motor. DC servo motor provides very accurate and also fast response to start or stop command signals due to the low armature inductive reactance. DC servo motors are used in similar equipments and computerized numerically controlled machines.
Ac servo motor
AC servo motor is an AC motor that includes encoder is used with controllers for giving closed loop control and feedback. This motor can be placed to high accuracy and also controlled precisely as compulsory for the applications. Frequently these motors have higher designs of tolerance or better bearings and some simple designs also use higher voltages in order to accomplish greater torque. Applications of an AC motor mainly involve in automation, robotics, CNC machinery, and other applications a high level of precision and needful versatility.
Positional rotation servo motor
Positional rotation servo motor is the most common type of servo motor. The shaft's o/p rotates in about 180o. It includes physical stops located in the gear mechanism to stop turning outside these limits to guard the rotation sensor. These common servos involve in radio-controlled water, radio-controlled cars, aircraft, robots, toys and many other applications.
Continuous rotation servo motor
Continuous rotation servo motor is quite related to the common positional rotation servo motor, but it can go in any direction indefinitely. The control signal, rather than set the static position of the servo, is understood as the speed and direction of rotation. The range of potential commands sources the servo to rotate clockwise or anticlockwise as preferred, at changing speed, depending on the command signal.
Industrial automation and robotics
Housed and frameless servo motors are advancing the state of the art for factory productivity, surgical precision, energy production and many other endeavors.
CNC machinery and machine tools
Servo motors bring the greatest possible precision and repeatability to shaping, grinding, drilling and other tooling applications.
Aerospace and defense
From surveillance, defense and weapon systems to the commercialization and exploration of space, servo motors are crucial to mission success.
Automotive applications and electric vehicles
Servo systems are improving efficiency and safety from the manufacturing floor to the distribution center and beyond.
Components of Servo Motor
The servo motor consists of a number of essential main components. These basic structural components include:
Housing、Stator、Rotor、Motor winding (inserted in the stator)、Cooling (optional)、Power connection、Feedback system (encoder)Further components are assigned to the motor itself. Among these, the servo controller is particularly important. This acts as an intermediary between the motor and digital control elements (e.g. PLC), as it converts the signals as required. Only in this combination is the servo drive complete. The following sections will take a detailed look at some of the components.
Motor shaft and motor winding
The shaft and the winding form the structural core of a servo motor. They function as the rotor and the stator. Looking at the servo motor from the outside in, the stator (with the motor winding) is located below the housing. The latter consists of an electrically highly conductive material and can have various designs: The wire can vary in thickness or diameter, which in turn influences the winding intensity. The thinner the wire, the more and tighter windings can be implemented. These have a significant influence on the specifications of the motor. Decreasing wire thickness and increasingly tight windings yield the following effects:amplified magnetic field、increased maximum torque、higher countervoltage with increasing speed、reduced efficiency、increased waste heat, which requires appropriate cooling.This means that a tighter winding of the stator results in extremely high power being converted at low speed. At higher speeds, there is a massive drop in power, but this drop is insignificant in these cases. The type of motor winding depends on the specific application.The rotor is the motor shaft located inside the stator. It is set in motion by the electromagnetic field of the winding as soon as energy is supplied from outside. The shaft then transmits the motion to the machine driven by the servo motor.
The right cooling – especially efficient with water
Cooling represents an essential part of a servo motor. In terms of applications, various forms of cooling come into question. They can work via air, oil or water. With water cooling, the highest nominal power can be implemented in a compact design. This means an increase in power density. Considering the increased costs entailed by higher space requirements as well as the loss of design flexibility, this increased power density is an important economic factor in the operation of any industrial machine.
Interaction with the servo controller
The servo controller is effectively the communication medium between the control unit (e.g. PLC) and the motor. It converts signals from both sides and transmits them further. The control of the motor behavior can be set particularly exactly.
Servo motors are essential tools used across various industries, but like any equipment, they are not foolproof and can face issues that affect performance and safety. Knowing how to troubleshoot common issues is essential to ensure you get the best performance from these motors.
One leading cause of servo motor failure is contamination. Oil, coolant, and debris can infiltrate servo motors and cause damage to critical components like bearings and windings, for example. You can fend off contamination by inspecting and cleaning your servo motors regularly. You could also consider sealing motor windings and using fully enclosed motor systems.
If you hear growling or shrieking noises when your motor operates at high speeds, it's a sign of bearing failure. This can be brought on by various factors, including typical wear and tear, and improper installation or reinstallation. Regularly inspecting and replacing bearings can prevent these failures and help extend your servo motor's lifespan.
Few servo motors escape the issue of overheating. High temperatures can cause damage to the internal components or connected systems, leading to costly downtime. Motor blockages, high ambient temperatures, and long operating hours are all common causes of overheating. Thankfully, many servo motors feature fail-safes that shut down the motor when things get too hot. Whenever possible, place your servo motor in a temperature-controlled environment with proper airflow.
While motor brakes play a critical role in stabilizing loads when your motor stops or powers down, these brakes are not designed for continuous and frequent use. To avoid brake failure, always engage the brake when the motor is at rest, allowing it to take a breather. If your application needs frequent stops or dynamic braking, look at brakes designed for that purpose.
Winding and cable issues are also common problems in servo motors. Contaminants, such as water exposure, or the motor's natural vibrations, can harm the copper coils inside. As time goes on, power and control cables can wear down and potentially cause motor failure or voltage spikes. To tackle winding problems, regular maintenance tasks like rewinding damaged coils can help. You should also choose top-notch feedback cables.
How to Maintain Servo Motor
Regular inspection
Perform visual inspections of the servo motor to check for any signs of damage, loose connections, or abnormal wear. Look for loose screws, damaged cables, or worn-out components. Inspect the motor's cooling system, such as fans or heat sinks, and ensure they are clean and free from debris.
Lubrication
Follow the manufacturer's guidelines for lubrication intervals and use the recommended lubricants. Proper lubrication helps reduce friction, heat, and wear within the motor. Pay attention to the motor's bearings and ensure they are adequately lubricated.
Cable management
Proper cable management is crucial for the reliable operation of AC servo motors. Ensure that cables are securely fastened and protected from potential sources of damage, such as sharp edges or excessive bending. Check for any signs of cable wear or insulation damage and replace damaged cables promptly.
Environmental considerations
Servo motors may be exposed to harsh environmental conditions in certain applications. Take measures to protect the motor from excessive dust, moisture, or temperature extremes. Use appropriate enclosures or covers to shield the motor from environmental elements that could potentially affect its performance and reliability.
Calibration and tuning
Periodically calibrate and tune the servo motor to maintain accurate control. Follow the manufacturer's guidelines for calibration procedures, which may involve adjusting the motor's feedback devices, controller settings, or gain parameters. Proper calibration ensures precise positioning and speed control.
Monitoring and diagnostics
Implement a monitoring system to track the motor's performance parameters such as temperature, vibration, and current draw. By monitoring these parameters, you can identify any abnormalities or early signs of motor degradation. Use diagnostic tools or software provided by the manufacturer to analyze and interpret the collected data.
Troubleshooting
In the event of a malfunction or unexpected behavior, troubleshooting techniques can help identify and resolve the issue. Start by checking the power supply and connections to ensure the motor is receiving adequate power. Inspect the wiring and connections for any loose or damaged components. Consult the motor's documentation or contact the manufacturer for specific troubleshooting steps.
Professional maintenance
For complex issues or major maintenance tasks, it is advisable to seek assistance from qualified professionals or technicians with expertise in servo motors. They can perform advanced diagnostics, repairs, or replacements when necessary.
