Servo motor damage analysis and preventive measures:
In the continuous long-time load working mode of Siemens servo motors, the bearing high temperature will appear over time, and the outer circle of the front end cover and the rear end cover will wear out, resulting in the burnout of the shaft extension end bearing of the motor, the rotor immobile current increases, and the temperature rises High, the insulation layer of the coil breaks down, causing a short circuit between turns and a short circuit between phases. It will also cause the encoder to be damaged by increased temperature.
Preventive measures and countermeasures
(1) Detect the running sound state of the motor during the inspection.
(2) Regular motor maintenance, add lubricating oil, replace bearings, and increase the insulation of the coil.
(3) In the operation management of the equipment, it is required to strengthen the operation monitoring of the equipment that has abnormalities (heat, abnormal sound, vibration), and timely shut down the equipment for maintenance. Servo motor damage analysis and preventive measures
The servo motor burned the encoder, the bad bearing was damaged, the overcurrent, and the brake could not be opened. The 1FK7 motor is a highly compact permanent magnet synchronous motor. According to different applications, you can choose the corresponding encoder. The integrated gearbox as an option and the wide product range make the 1FK7 motor easily applicable to various occasions. They can meet users' requirements for machine excellence. The organic combination of 1FK7 motor and SINAMICS S120 high-performance drive system can complete the speed and position control. The 1FK7 motor is only cooled by natural air, there is no external cooling system, and the heat is dissipated through the surface of the motor. 1FK7 Very strong overload capacity 1FT6086-8AC71-1TA01FT6084-8WF71-1AG01FT5108-0AC71-1-Z1FT6084-8AC71 (only applicable to 1FK701 to 1FK703) H-value encoder EnDat 32S / R (not applicable to 1FK701 to 1FK703)
