Product Description:

The MHD093B-035-NG1-RN servo motor is built by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It converts drive commands into controlled rotary motion for automated axes that demand precise positioning in packaging, handling, and machining cells. The unit integrates optical position measurement and an internal holding brake, allowing it to follow dynamic trajectories and secure the load when power is removed.

At standstill the motor supplies a continuous torque of 17.5 Nm, letting machinery hold process forces without overheating. Heat generated in the stator is carried away by the integrated liquid cooling jacket, maintaining thermal stability during high duty cycles. Installation is through a square flange of 140 / 150 mm that registers on a 130 mm centering pilot for concentric alignment. The enclosure has an IP65 rating, protecting the windings and bearings from dust and low-pressure water jets common on factory floors. Position repeatability is enhanced by a system accuracy of ± 0.5 angular minutes, which suits indexing tables that require tight angular tolerances. The optical measurement method and relative position detection support this feedback performance.

During power-off conditions, an integrated brake supplies 22.0 Nm of holding torque to prevent unwanted motion. Rotor angle is reported by digital servo feedback (HSF), giving high-resolution data to the drive for accurate motion control. Class F insulation allows elevated winding temperatures incurred by rapid acceleration profiles. Reliable service is specified across an ambient range of 0 to 40 °C; storage from −20 to +80 °C and mounting up to 1000 m above mean sea level are also permitted. The motor has a plain shaft with a shaft seal and a right-side power connector. It uses winding code 035, motor length B, and frame size 093.
