  1. Servo motor failures occur often

  2. Servo motors, also known as AC synchronous motors, are used by machine builders for a range of tasks. They are up to 60% more energy efficient and have a torque capability that is up to 60% higher than comparable-sized induction motors. Like any tool, servos are subject to failure, and these motor malfunctions may negatively impact both production and safety. Understanding the most common causes of servo motor failure is vital because of this. By paying attention to these very avoidable issues, you can minimize downtime and make sure that these motors operate at their best throughout their lifespan.

  3. 1. A Bearing's Deterioration Bearing failure, which occurs commonly in servo motors, can be caused by a variety of circumstances. Naturally, as bearings are used more frequently, they become less effective. Due to poor motor installation or reinstallation, these bearings may fall out of alignment. While the engine is running at high speeds, an odd sound, such as growling or screaming, will be discernible when a bearing fails. Predictive maintenance is the most successful tactic to avoid bearing failure. If the bearings are periodically inspected for deterioration, the motor's lifespan will be significantly increased. This will also allow for the scheduling of repairs at times when they won't hinder productivity. To ensure proper bearing replacement, working with a reliable repair partner is crucial. Critical applications should consider employing

  4. 2. Inadequate Braking When the drive is stopped or switched off, the weight is kept in place by servo motor brakes. The majority of servo motor brakes are designed exclusively for holding rather than dynamic stopping. The brake may need to be replaced if it is used frequently or during several e-stops because of wear and tear. Because many servo motors are manufactured with IP65 protection, the brake is frequently enclosed within the housing and is difficult to examine or repair. When stopping, always use the engine brake. Once the brake is engaged, it is possible to cut off the motor's drive current. If the machine occasionally has to do an e-stop and dynamic stopping, a separate brake with the recurring application should be used.

  5. 3. Cable and winding malfunctions The most frequent cause of Servo motor repair failure is defective winding. These copper coils inside the motor are susceptible to harm from water contamination or, more gradually, from natural vibration while the motor runs. The system's power, control, or feedback cables might deteriorate with time, much like a motor that can shut off as a result of voltage spikes or failure. The precise source of the issue can be found by fixing servo motors. If the servo motor has been exposed to any pollutants, such as coolant or water, it is imperative to check for winding breakdown. Because windings age and deteriorate with time (more on this below), even clean ones need to be examined. Winding the broken coils will lengthen the life of the motor. Purchasing dependable cables is one of the best ways to avoid cable failures. Fast, error-free connections are made possible by a good feedback cable, which improves system performance as a whole. Cables should always be periodically inspected as part of your troubleshooting processes, regardless of how good they are.

  6. 4. Contamination Contamination is at the heart of many of the motor issues we've discussed thus far. Despite their generally robust nature, several substances, including coolant, oil, and even common debris like dirt, can seriously harm servos. The latter might overheat the gadget by clogging fans and other essential system components. Liquid contaminants have the potential to harm the motor's windings, encoder, and other parts. Servo contamination must be avoided, hence regular inspections and cleanings are required. Sealing the motor windings and adopting entirely enclosed motor systems can help prevent these toxic components from entering and having an impact on the system, especially in challenging climatic conditions.
