Siemens servo motor demagnetization and displacement repair

Shanghai Quli Automation Technology Co., Ltd.: Siemens CNC system servo motor maintenance is a complex technical service industry. In recent years, servo motors have been used more and more widely, and the use of the market in Chinese Mainland has increased rapidly. The demand for technical services such as spindle motor maintenance has become increasingly urgent. Due to the fact that most of the servo motors used in China are imported products with high technological content, foreign servo motor manufacturers have adopted non-standard encoders or installation methods in order to monopolize the maintenance service market, making spindle motor maintenance more difficult and forming servo motor maintenance as an outstanding technical skill.Siemens servo motor demagnetization and displacement repair

Siemens servo motors are one of the core components in the field of industrial automation control, widely used in various industries such as machine tools, robots, printing equipment, packaging equipment, food processing equipment, textile equipment, medical equipment, etc. During long-term use, the servo motor may experience some malfunctions and require maintenance. To ensure the normal operation of the equipment, the following areSiemens servo motor maintenance planDetailed introduction.

1、 Troubleshooting

Before carrying out servo motor maintenance, it is necessary to first troubleshoot and determine the cause of the malfunction. Generally, we can start from the following aspects:

(1) Check if the power supply circuit is normal and if there are any issues such as short circuits or open circuits;

(2) Check whether the encoder and feedback circuit are damaged or have poor contact;

(3) Check whether the rotor and stator are damaged or worn;

(4) Check if the drive is functioning properly, including checking for issues such as overcurrent, overheating, and overvoltage.

Through the above investigation, the cause of the servo motor malfunction can be determined, and corresponding maintenance plans can be formulated accordingly.

2、 Repair plan

1. Replace damaged components

After troubleshooting, it is necessary to replace the faulty components to ensure the normal operation of the motor. If overcurrent issues are found in the drive, it may be necessary to replace the drive; If the encoder is damaged, it needs to be replaced.

2. Recalibrate

After replacing the damaged parts, recalibration is required. The calibration steps include:

(1) Encoder calibration: Encoder calibration is to ensure that the motor controller can correctly read the encoder feedback value. The calibration method is to set corresponding parameters in the motor controller and match the encoder signal with the controller;

(2) Position calibration: Position calibration is to ensure that the motor can stop moving at the correct position. The calibration method is to stop the motor at a preset position and set that position as the origin.

3. Preventive measures

In addition to maintenance, we also need to take some preventive measures to avoid similar problems. The specific measures are as follows:

(1) Regular inspection: Regularly inspect servo motors to promptly identify and resolve issues;

(2) Regularly replace parts: For vulnerable parts, replace them regularly to avoid issues such as excessive wear and tear;

(3) Pay attention to the usage environment: Place the servo motor in a dry, ventilated, and suitable temperature environment to avoid excessive dust accumulation or high temperatures.
