Keeping the servo motor running at its best is very important for any industrial enterprise, especially in industries like robots or CNC equipment tools. The cost of downtime on account of servo motor failure may be very expensive, both economically and economically. Still soon enough.
Next, let’s take a review of some of the most popular servo motor failures and also their potential causes to use to get around all of them.
Bearings
Servo motors typically ac motor area a bearing on each of the drive side and the non-drive side for connecting and support the continuous motor shaft. The axial and/or radial loads in which the drive-side bearings are that will support external mechanical connections generally have a very large size and the whole length load. Servo motor ball bearings are often double-protected and permanently lubricated and tend not to require maintenance under normal conditions people.
Fault phenomenon
Bearing failure is probably the most common motor downfalls. As the main use part in servo power generators, more than half involving servo motor failures are usually attributed to bearing injury. The specific performance belonging to the motor can be varied. If the motor rotates, the idea generates jitter, abnormal noise, etc.,and the motor shaft is stuck.
It is worth noting that impact failures, if not asynchronous motor dealt with in a timely manner, often bring secondary problems. For example, crushed bearing debris flies in the brake or motor encoder, causing more serious losses.
possible cause
Factors that affect all the memories of a motor bearing include: axial load acting within the bearing, radial load, generator speed, operating temperature, in addition to bearing rating parameters. There are various causes of bearing failures, common ones include.
But the practice of regular maintenance can avoid danger of accidental downtime, it’s not the most economical process. Because of the distinct operating conditions of various applications, the situation of bearing wear varies. By analyzing the actual use of the motor by a shrewd sensor (or diagnostic information provided by a smart encoder) attached to that motor, more targeted maintenance could be achieved.
When bearings get abnormal conditions or his or her service life expires, utilised together be replaced in time. Replace the bearing number should be just as the original bearing. Demolition on the bearing should use your special drawing die to the bearing. The assembly of the bearing is recommended to utilize the cold pressing approach (the heating method can easily cause the foreclosure of the internal grease on the bearing).
Shaft seal
For motor applications (especially wherever motor shafts are powering mechanical equipment) exposed that will contaminated environments, servomotors generally require oil seals. Shaft seals for motor shafts can easily block pollutants (oils, impurities) to extend motor life. Shaft seals are at the mercy of wear and require standard inspection and replacement.
