Mitsubishi HG-SR524BG5-1-21 AC Geared Servo Motor with Brake

The Mitsubishi HG-SR524BG5-1-21 (HG-SR524BG5-1-21) is a high-performance rotary AC geared servo motor designed for precise positioning and motion control in demanding automation environments. Developed as part of the Mitsubishi HG-SR series and compatible with MELSERVO drive systems, this motor serves as a direct functional equivalent to the HKST502BG715 model. The unit incorporates an integrated electromagnetic brake that secures the load safely during power loss or system stops, making it suitable for vertical axes and fail-safe holding applications. Equipped with a built-in 26-bit absolute feedback encoder, the HG-SR524BG5-1-21 delivers high positioning resolution and stable closed-loop feedback without requiring zero-point homing routines after power interruption. The motor features an integrated high-precision 1/5 reduction gearhead with a straight shaft output, providing multiplied output torque and consistent speed reduction for heavy-load operations. Typical applications include CNC machinery, automated assembly systems, packaging equipment, indexing tables, and transfer units where dependable mechanical braking, compact gear reduction, and absolute position tracking are critical.
