Product Description:
The MHD093B-035-NG0-RA/S018 is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Designed for integration into CNC machines and automated production lines, the unit converts electrical energy into controllable mechanical rotation so that drives can position loads quickly and repeatably. Its compact frame and digital feedback capabilities make it suitable for multi-axis systems that demand synchronous motion.
The motor delivers a continuous standstill torque of 17.5 Nm, allowing stable holding force without overheating when energized but motionless. A centering diameter of 130 mm aligns the housing with machine frames, and the plain shaft simplifies coupling to gearboxes or pulleys. The IP65 rating helps protect the stator against dust ingress and water jets, while operation is permitted at ambient temperatures from 0 to 40 °C. Position feedback is provided by digital servo feedback (HSF), which is read optically, and the system evaluates incrementally to a system accuracy of ± 0.5 angular minutes. Relative position detection works with the controller to maintain axis reference after homing. The winding code 035, motor size 093, and length code B indicate the electrical characteristics and mechanical depth within the series. Power is routed to the right through a molded power connector, and the motor does not include a holding brake.
Thermal management relies on natural convection, so the motor can be installed where forced airflow is unavailable, provided the installation height does not exceed 1000 m above mean sea level. The windings use class F insulation materials for a permissible winding temperature of 155 °C, and long-term storage is allowed from -20 to +80 °C. Mounting holes follow a flange pitch of 140 / 150 mm, and a factory-fitted shaft seal helps prevent lubricant leakage when the drive is paired with gear reducers.
