Product Description:
The MHD093B-035-NG1-RA servo motor is produced by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. Designed for closed-loop motion axes, the unit converts drive current into regulated rotary motion for functions such as indexing tables, pick-and-place modules, and machine-tool positioning. An integrated optical encoder generates relative position data that are fed back to the drive controller. By combining a medium frame size with the 035 winding code, the motor offers a balance of speed and torque for general-purpose automation tasks.
At stall, the rotor can deliver 17.5 Nm of continuous torque, while the flange interface measures 140/150 mm and aligns with a 130 mm centering recess to simplify mounting against standard gearboxes. The motor is sealed to IP65, which helps protect internal components from dust ingress and low-pressure water jets, and a shaft seal is fitted to support that protection when the motor is coupled to external equipment. Heat is removed by natural convection, so cabinet airflow is not required. Position information is captured through digital servo feedback (HSF) using an optical measurement method that supplies high-speed incremental and absolute data to the controller. Power enters through a right-side power connector, and the maximum installation altitude is 1000 m above mean sea level.
The holding brake supplies 22.0 Nm of static torque, preventing unwanted motion during power-off events. The motor uses F-class insulation and is rated for continuous duty between 0 to 40 °C, while storage is permitted from -20 to +80 °C. System positioning is reproducible within ± 0.5 angular minutes, which suits mid-precision axis drives. The motor has length code B, which helps keep inertia suitable for rapid starts, and the relative position feedback system requires a homing routine after each power-up.
