Every servo motor owner would come to a point where they believe it’s time to have the servo motor checked or repaired. If your servo motor is making strange noises, rotating incorrectly, or having issues, then it’s high time to have a servo motor repair. The following are some tips on troubleshooting common servo motor problems. 1. To know if your motor is still operating properly, you can check the ground resistance in-between the motor body and terminals. It should show approximately 100 ohms. If it is below 100 ohms, then something is not right with your motor. 2. Find the winding resistance. You can do this by simply connecting between the terminals. It should show 200 ohms. For those who have larger motors, it should reflect lower values. On the other hand, those who have smaller motors should have an ohm value around 100. 3. Checking the motor at the winding terminals is also advisable as compared to checking it at the cable end. Checking out at the cable end could not be 100 percent correct as it might already be corroded or broken. 4. Another tip is to disconnect the conductors. You should be able to see values that represent they are functional. The values depend on the size of your motors. 5. If you still something is not right with your motor, recheck the terminals. Remember not to do anything with your motor unless you are trained and experienced in servo motor repairs. Troubleshooting your servo motor actually depends on the issue you are faced with. However, these problems can be categorized into groups such as the following: Uncontrollable axis a.Command signal wiring is either incorrect or open. b.There is a malfunctioning in the internal system. c.Power shortage in the transistor module(s) exists. d.JP1 is set incorrectly. Unstable axis or system a.Velocity Loop Compensation or GAIN potentiometer is not set correctly. b.Accel/decel rate is not properly set. c.Noise are present due to improper grounding or shielding techniques. d.Incorrect jumper placement. On the other hand, if you are busy with other things and got no time to self-check or troubleshoot your servo motor, then you have the option of shipping it to the manufacturing company or look for servo company repair shops. These shops have specialized technicians that are capable of pointing out what the problem is. Also, shops are equipped with the best test and repair equipment that are capable of repairing shafts, sleeve end bells, or even motor housings. It is actually advisable to look for a service shop or an experienced technician to do the dirty work. They have more knowledge in the area and are trained in the field. Chances are that doing the dirty work yourself can cause more problems than actually provide solutions to the already existing problems.here are several motor service repair shops available in your area. When choosing, make sure to consider factors such as the equipment available, the experience of the technicians, the location, the place, and the services offered.

Just like other equipment, your servo can worn out due to wear and tear. Especially if it has aged already, you need to constantly check it for consistency. If your servo equipment is losing its efficiency, then it is probably time that you contact a servo motor repair service to do the fixes and make your servo in condition. So what are the signs that your servo needs repair? In this article, you will learn the top 10 signs that your servo needs repair. Weird sounds or noisy equipment. If your servo equipment is louder than usual, it is a sign that the engine is about to crash or that your bearings are getting worn out. When not given attention, this could lead to potential destruction or malfunction of your servo. Noisy engine is also a sign that your fan is becoming rusty or the shaft is not fitting right. Before everything is too late, it is important that you have it checked by a servo repair company for a safer work. Amps are drawing high. If your servo equipment is drawing high amps, it means that your internal winding is experiencing failure or your internal component is having some issues. Servo motor repair can test it to confirm whether or not there are grounded electrical parts or if the servo motor feedback are still aligned correctly. Faults in servo equipment. When your servo is very old already, it can suffer from thermal faults and over currents. If you don’t give attention to it, this can lead to short circuits which eventually cause your servo to stop functioning. Obvious physical damage. Light damages such as scratches in the surface due to mishandling or fork lift may not need heavy repair. But some damages such as corrosion due to old age or missing parts needs immediate repair. Corrosion can spread rapidly and if you don’t resolve it, it will destroy your servo. Your heatsinks are dirty. If you have not checked your servo for a while, it is probably having some issues with the heatsink right now. Some signs that your heatsink needs cleaning include engine malfunction, breakdown, or sudden blow in the IGBTs. Servo motor repairs company can fix these problems by brushing and cleaning the heat sink. They can also perform some test in other important parts that may have also contributed to the heat sink malfunction. Internal contamination. When your servo is dirty outside it can follow that it is also dirty inside. Dusts, coolant, and moist can generally form dirt inside which can cause your servo to malfunction. When your servo is contaminated, it can lead into overheating, component failure and severe damage to the servo itself. The cooling fans are no longer function. Damaged fans is a serious problem that you need to resolve immediately. Fans are one of the most important components of a servo, especially that they are needed for cooling. Some damages in the fan area are caused by overheating or overusing, damage in the IGBT, or damage in the sensors. Normally these problems involve internal component repairs which only a company trained for such specific thing can do. When confronted with this situation call a servo motor repair service immediately. Although servo motors are basically built with strong components, they can become less and less efficient as time goes by. Especially if your servo is on heavy duty, you need to be on watch of the inevitable damages that can occur anytime. Whenever you notice that something is seriously wrong with your servo, don’t for the time to decide for you. Contact the nearest servo motor repair company in your area and have it checked.
