Mitsubishi HG-SR52BG7-1-21 Rotary AC Geared Servo Motor with Brake

The Mitsubishi HG-SR52BG7-1-21 (HG-SR52BG7-1-21) is a high-performance rotary AC geared servo motor engineered for industrial motion control applications within the MELSERVO family. Designed with an integrated electromagnetic brake and a keyed shaft output, this unit delivers reliable holding and precise driving capabilities under demanding operating conditions. It features a factory-fitted 1/11 ratio standard gear head with a foot-mount reducer configuration, providing balanced torque multiplication and smooth rotational operation for positioning tasks. Feedback is provided by a high-resolution 26-bit integrated absolute encoder, ensuring accurate velocity regulation, steady low-speed operation, and reliable multi-turn position tracking without requiring constant homing routines. Equivalent to model HKST52BG1H111, this motor is well suited for demanding production machinery, automated conveyors, indexing tables, material handling systems, and assembly lines requiring compact integration, secure load braking, and exact positioning accuracy.
