There are numerous reasons why Servo Motor failures happen. It’s crucial to understand the preventative maintenance measures you can implement to minimise the likelihood of unforeseen motor failures. A Servo Motor can be affected by Electrical, Mechanical, or Environmental factors, which can hinder its operation. 

Run Testing a Servo Motor

Most manufacturers estimate a machining lifespan of 20,000 to 30,000 working hours for servo motors, although this can fluctuate based on the application and maintenance performed on the servo. 

This blog will explore 5 potential causes of Servo motor failures and suggest methods to optimize the efficiency of the Servo Motor. 

Continual operation of a servo motor at high temperatures, or without adequate cooling intervals can lead to overheating. Persistent overheating can eventually lead to motor failure, as it damages the internal insulation and diminishes the motor’s efficiency. 

To avoid overheating in the Servo, it is advisable to improve the regulation of heat distribution within the servo. Regular upkeep of the servo can help detect worn-out parts; replacing these parts can minimize the heat generated during rotation. Allowing extended cooling periods will assist the motor in resetting its temperature before it starts operating again. 

Degraded Bearings 

Continuous spinning inside the Servo can degrade specific parts, with bearings being a prime example. When a bearing deteriorates, it can cause the motor to become loud or even stall. Bearings play a crucial role in a servo, as their degradation can affect the accuracy during machining. 

Increased friction is produced when bearings are worn out. This friction can elevate the temperature while the motor is in operation, and potentially lead to the motor overheating, which is an adverse effect. 

Environmental Consequences 

The environment in which the Servo motor operates can influence its effectiveness, especially if it’s not an appropriate setting. Environments that are corrosive, hot, or humid can heighten the risk of motor breakdowns and diminish the dependability of the Servo Motor. This factor should be considered when choosing the motor for a specific task, ensuring it can endure the environmental conditions. 

Intrusion of dust or liquids can negatively affect the motor and its internal parts. Monitoring the dust accumulation within the servo is crucial, as excessive dust can pose a fire hazard within the motor. 

Servo Motor Maintenance Obligations 

Maintaining machinery is crucial for detecting and fixing issues before they inflict internal damage to other parts. Regular inspections of lubrication levels, cleanliness, and motor balance are essential aspects to be examined when the motor is frequently in operation. 

Servo Motor Vibration Issues 

Vibration in the motor can lead to misalignment, as the motor’s movement can displace internal components. If your servo is vibrating, this is an indication that it needs to be inspected and rebalanced to reduce the vibration. At our Neutronic workshop, we utilize our CEMB 2000 or ZB20/TCN/GV balancing machines, essential tools for motor repairs. Every motor that exits our workshop is rebalanced to G1.0, enhancing its efficiency and lifespan. 

Our servo motor specialists at Neutronic possess the skills to detect, correct, and test the servo motor to ensure it operates at OEM specifications. Email Neutronic today to schedule your Servo Motor repair today!
