Siemens spindle motor maintenanceReplacement of front and rear bearings; Many people have basic skills in motor repair, but when it comes to motor components, they may not necessarily know how to repair them. Now let me share with you the repair of motor components:
(1) Repair of motor fan and fan cover
When the external fan or fan cover of the electric motor is damaged, attention should be paid to the distance between the fan and the fan cover, baffle, and fasteners, which should not be less than 1% of the fan diameter, at least 1mm, to avoid friction and collision sparks. If replacing the external fan, the magnesium content of the aluminum alloy fan should not exceed 6%. If replacing with a plastic fan, accessories that have undergone explosion-proof testing should be selected. When repairing or replacing the fan cover, its protection level should meet the requirements of explosion-proof standards.
(2) Repair of explosion-proof shell
If there are cracks in the shell of the explosion-proof motor, it is recommended to replace it with new identical parts. If small defects are found on the explosion-proof surface, they can be repaired according to the requirements of GB3836.13. Changing the roughness and coating of the outer surface of the motor should consider the impact on the surface temperature and temperature group of the motor.
The shell of the increased safety motor is a protective shell, which can be repaired using the same process as repairing the shell of general electrical products to restore its original shell protection level.
The servo system is mainly composed of servo motors, servo drives, servo encoders, power modules, and other parts. Any failure of any part can cause the motor to not work properly. Common faults include: coil short circuit and burnout, brake jamming, brake failure, inability to start, weak starting, running shaking, demagnetization, overcurrent, overload, positioning, output imbalance, encoder alarm, encoder damage, inaccurate position, alarm as soon as power is turned on, tripping as soon as power is turned on, magnet explosion and steel jamming, encoder wear, motor heating and overheating maintenance, abnormal motor operation, etc. The solutions include:
1. The encoder settings in the servo controller are incorrect. Modify the parameters.
2. Signal interference, improve grounding and shielding.
3. The motor bearings are damaged, repair the motor.
4. If the encoder or encoder cable is damaged, replace it.
5. If the encoder interface of the servo controller is damaged or has poor contact, repair it.
