Mitsubishi HC153BS-SZ-E51 Geared AC Servo Motor with Brake

The Mitsubishi HC153BS-SZ-E51 (HC153BS-SZ-E51) is a high-performance rotary AC geared servo motor designed for precise positioning and industrial motion control. This motor features an integrated electromagnetic holding brake and a built-in 26-bit absolute feedback encoder, delivering accurate closed-loop feedback and reliable position retention during power interruptions. Engineered with a keyed shaft and a factory-fitted standard 1:6 gearhead, it provides increased torque transmission and smooth speed reduction for high-load automation tasks. As part of Mitsubishi Electric's motion control ecosystem, this drive unit matches applications requiring controlled deceleration, high mechanical stiffness, and dependable holding capabilities. It serves as an equivalent replacement solution for HKST702BG116 configurations within the MELSERVO J5 series lineup. The integrated gear reducer assembly and robust electromechanical design make it well-suited for industrial machinery, packaging equipment, robotic axis positioning, material handling systems, and automated production cells that demand exact rotary indexing and steady load management.
