Working principle

The YASKAWA SGDS-08A01A high-performance servo motor, as the core power execution component of industrial automation systems, works based on the full process servo drive logic of "electromagnetic induction drive position/speed feedback closed-loop control". Firstly, the servo motor receives three-phase AC power from the servo driver through the U/V/W power interface. The current generates a rotating magnetic field in the stator winding, and the rotor rotates with the rotating magnetic field under the action of electromagnetic attraction, outputting mechanical power to drive the load operation; At the same time, the built-in 20 bit high-precision absolute encoder of the motor collects real-time position and speed signals of the rotor, and feeds back the signals to the servo driver through the encoder interface; The servo driver compares the feedback signal with the instruction signal issued by the upper computer (PLC/motion controller), dynamically adjusts the current size and frequency output to the motor, and achieves closed-loop control of position, speed, or torque; In addition, the built-in protection circuit of the motor monitors parameters such as stator winding temperature and operating current in real time. Once abnormalities such as overheating, overcurrent, and overload are detected, the fault signal is immediately fed back to the servo driver, which quickly cuts off the power output, achieving safety protection for the motor and load equipment.

Installation and usage precautions

（1） Installation precautions

-Voltage and driver matching: Before installation, it is necessary to confirm that the output voltage and current of the servo driver are consistent with the rated parameters of the motor (AC 200V, 4.5A), to ensure accurate compatibility between the driver and motor models (priority should be given to matching Yaskawa SGDS series drivers); It is strictly prohibited to directly connect power sources that do not meet the parameters to the motor to avoid motor burnout or performance damage; When not in use for a long time, the motor should be disconnected from the driver and protected against dust and moisture.

-Installation environment requirements: The installation position of the motor should be away from strong electromagnetic interference equipment such as welding machines and high-power frequency converters to avoid electromagnetic interference affecting the transmission of encoder signals; The installation location should ensure good ventilation and maintain a distance of ≥ 50mm from other equipment to ensure smooth heat dissipation of the forced air cooling device; It is strictly prohibited to install in environments with direct sunlight, high temperature and humidity, high concentration of corrosive gases or dust, to avoid damaging the motor winding and encoder.

-Correct wiring and mechanical installation: Strictly distinguish the power interface (U/V/W) from the encoder interface according to the wiring manual, strictly prohibit misconnection or mixing, and avoid motor reversal or encoder damage; Special shielded cables should be used for power cables and encoder cables, with a distance of ≥ 300mm between them to reduce signal interference; During mechanical installation, it is necessary to ensure that the coaxiality error between the motor shaft and the load shaft is ≤ 0.02mm to avoid bearing wear or vibration caused by eccentric operation; The installation bolts should be tightened to the specified torque to prevent loosening during operation.

（2） Precautions for use and maintenance

-Parameter configuration and trial operation specifications: Before the first use, the motor parameter configuration needs to be completed through the servo drive matching software, including motor model adaptation, encoder type selection, control mode setting, position/speed parameter calibration, etc; After the parameter configuration is completed, a no-load test run is required to check whether the motor direction, speed, and vibration are normal, and then a load test run is carried out to confirm that there are no abnormalities before it can be officially put into use; Prohibit arbitrary modification of core drive parameters to avoid abnormal motor operation or decreased positioning accuracy.

-Regular maintenance: Regularly check the operating status of the motor, including shell temperature, vibration, noise level, cable connection tightness, etc; Regularly clean the motor cooling duct and fan dust to ensure smooth heat dissipation; Regularly check whether the encoder signal cable is damaged and whether the interface is loose; It is recommended to conduct a comprehensive insulation test and parameter calibration every 6 months, and check the bearing wear and add lubricating grease every 12 months.

-Fault handling specifications: When a fault occurs, it is necessary to first read the fault code through the servo drive and investigate the cause of the fault based on the motor operating status (such as checking the cooling fan and ventilation situation for overheating faults, and checking the encoder and coaxiality for positioning deviation faults); It is strictly prohibited to forcibly start the motor without troubleshooting; When replacing components such as encoders and fans, it is necessary to use Yaskawa original parts to ensure equipment compatibility and operational reliability; Complex faults require maintenance by professional technicians.
