Siemens servo motor housing replacement, flange replacement, maintenance

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.
Professional maintenance of various brands of servo motors for repair faults: magnet explosion, magnet detachment, stuck rotation, encoder wear, code disk/glass disk wear and tear, motor overheating, motor water ingress, motor abnormal operation, high-speed operation noise, loud noise, brake failure, brake pad wear, low-speed normal high-speed deviation, high-speed normal low-speed deviation, start alarm, start trip, overload, overvoltage, overcurrent, unable to start, weak start, operation shaking, demagnetization, running position, walking deviation, output imbalance, encoder alarm, encoder damage, inaccurate position, alarm when powered on, tripping when powered on, driver server alarm code, burnt coil winding, aviation plug damage, incorrect origin position, encoder debugging/zero adjustment. Replacing bearings, bearing groove wear, rotor fracture, Shaft fracture, gear groove wear, etc
This article will share common faults and corresponding maintenance methods of Siemens servo motors, hoping to be helpful to users.Siemens servo motor housing replacement, flange replacement, maintenance

1、 Preliminary preparation for starting servo motor:

1. Measure insulation resistance;

2. Measure whether the power supply voltage and motor wiring meet the requirements;

3. Check if the starting equipment is in good condition;

4. Check if the fuse is intact;

5. Check if the motor is properly grounded and zeroed;

6. Check if there are any defects in the transmission device;

7. Check if the motor environment is good and free of combustibles;

2、 Siemens servo motor temperature rise too high or motor smoking fault:

Reasons: excessive load, two-phase operation, air duct blockage, high working environment temperature, stator winding short circuit or grounding, high or low power supply voltage;

Maintenance: Reduce the load, select a large capacity motor, remove the air duct, cool down, and use a multimeter to check the input power voltage;

3、 Electric sparks in the motor housing:

Reason: The stator winding is damp, the insulation material is aging, and the outgoing line collides with the junction box casing;

Maintenance: Replace the stator winding and dry it;

4、 Abnormal vibration of motor:

Reason: Unbalanced rotor, bent shaft, unbalanced pulley, uneven air gap, resulting in unilateral magnetic tension;

Maintenance: Correct the dynamic and static balance, correct or replace the shaft, and readjust the air gap;

5、 Siemens servo motor current three-phase imbalance:

Reason: The power supply voltage is severely insufficient, the three-phase turns are not equal, and the internal wiring is incorrect;

Maintenance: Check the power supply voltage, replace the motor, and calibrate the wiring;

6、 High no-load current of the motor:

Reason: Large air gap between the stator and rotor, insufficient number of turns in the stator winding, and improper assembly;

Maintenance: Reduce the air gap between the stator and rotor, recheck, upwind, and reassemble;

7、 The insulation resistance of Siemens servo motors is significantly reduced:

Reason: The stator is damp, there is too much dust, the insulation material is damaged or aged;

Maintenance: Drainage, dehumidification, ash removal, repair or replacement of insulation materials;

The above are the faults and maintenance methods of Siemens servo motors.
