Why do servo motors fail?

Servo Motor

Some of the most common parts in today's highly automated facilities are servo motors. According to CM Industry Supply Automation, They play a crucial role in the operation of sophisticated machinery and fine tools, including multi-axis milling machines and assembly robots. Naturally, if these parts malfunction, the equipment they are powering will also stop working. Sadly, servo motors do occasionally break down for a variety of causes.

Basics of servo motors

Servo motors are crucial parts that possess and exert a lot of power. Servo motors operate a variety of gear and equipment on the factory floor, including cutting-edge technology like robotics or anything with an automated process. They have a positioning device that offers helpful feedback and further control.

Servo motors are used in almost every industry to power machinery and facilitate daily tasks. Production on the manufacturing floor can halt instantly if even one motor is broken or defective. It is imperative to perform routine maintenance on servo motors to maintain their integrity and functionality.

Typical reasons for servo motor failure

While there are warning indicators that a servo motor may be failing, routine inspections are the only way to guarantee operation. The simplest method for identifying typical catalysts that lead to failure is to routinely check the integrity of servo motors. The following are some of the variables to monitor and correct:

Overheating and excessive heat. Overcurrent on the machine brought on by mechanical faults such brake troubles or failed mechanical binding frequently leads to overheating. Replace worn out parts, use fans, and give the motor periodic breaks to promote adequate cooldown to control servo motor temperature.

Particles of pollution. Due to the inherent dirtiness of factories, it is not surprising that contamination from dust, oil, and other substances can enter servo motors and have an impact on everything from brakes to bearings. It is necessary to disassemble, clean, and reassemble a filthy servo motor.

Failures caused by a bearing. The high-pitched whining noise that bearing-related issues make is easy to identify. Changing the settings of the servo motor can fix the problem, whether the bearing is worn out or not greased. You'll most likely need to replace the bearing if that doesn't work.

Electrical errors and malfunctions. Even though servo motors drive mechanical equipment, any of its electrical components could experience issues. This include making whether the drive, positioning controller, and other electrical components are functioning as intended and looking for any problems.

Errors and failures due to mechanics. Servo motor failure is caused by mechanical problems. Mechanical parts, such as drive gears and circuits, can deteriorate over time, preventing a servo motor from providing sufficient power to equipment. Mechanical issues frequently result from maintenance mistakes.

Neglecting maintenance. Servo motors require routine maintenance, and if they aren't, they could break down at any time. Without adequate care, bearings could wear out, fluids could accumulate over time, and many other issues could develop. Regular maintenance appointments help prevent total failure and the pricey fixes that go along with it.

Value of professional diagnosis and treatment

The fact that not every servo motor involves the same factors makes it prudent to use the trained eye of a maintenance specialist when identifying and fixing problems. You can reduce the high costs of servo-induced downtime and maintain output by investing in regular maintenance and building a strong collaboration with a reliable maintenance provider.
