The Yaskawa SGM7J-08AFC6E is a rotary servo motor from the SGM7J series, designed for high-speed applications without a gearbox, featuring medium inertia. It operates at a rated speed of 3000 r/min and delivers a rated output of 750W, supported by an AC200V power supply. The motor is equipped with a 24-bit incremental serial encoder, ensuring high-resolution feedback for precise control. Its design sequence is designated as "C," and the shaft end is a straight shaft with a keyway and a threaded hole. Optional features include an oil seal and a holding brake (DC24V).

This motor is engineered to maintain stable operation even when the load inertia or the state of the cantilever changes. It offers improved responsiveness, achieving approximately twice the response performance of conventional models without the need for adjustment. Stability is also enhanced, ensuring smooth operation even in systems with fluctuating loads. Gain adjustments are unnecessary, as the motor guarantees performance with zero tuning time.

The system is protected against abnormal temperature conditions. Both the servo motor and servo unit are equipped with temperature sensors that directly monitor the temperature state of the components. This enables early detection and prevention of potential faults. Additionally, the system allows the machine controller to monitor temperature conditions, providing safe and reliable operation.
