Product Description:
The MHD093B-035-NG1-BA is a servo motor from the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It converts drive signals from a matched inverter into torque for machine tools, packaging stations, and material-handling axes that operate with digital feedback control. This motor is suited for applications that require stable speed regulation and accurate positioning during repeated motion cycles.
This motor belongs to size 093 with a length code B and develops a continuous standstill torque of 17.5 Nm. The housing is rated IP65, which helps keep dust and water jets away from internal components during normal service. The centering pilot on the mounting flange measures 130 mm, and heat is removed by natural convection, so no auxiliary fan is required. Winding code 035 identifies the stator resistance and inductance used by the matching Bosch Rexroth drive, and normal operation is permitted from 0 to 40 °C. Position data come from an optically read digital servo feedback encoder that provides relative position information to the controller. The motor has a plain shaft with a shaft seal, power is connected through a connector on side B, and insulation class F materials are used in the stator. Installation is permitted up to 1000 m above mean sea level without derating.
A holding brake is fitted and provides 22.0 Nm of static torque to secure vertical or overhung loads when power is removed. The square mounting flange uses bolt patterns of 140 / 150 mm, which supports compatibility with related Rexroth motor mountings. Closed-loop performance is supported by a system accuracy of ± 0.5 angular minutes, which helps reduce following error in precision indexing tasks. Storage temperatures from -20 °C to +80 °C can be tolerated without damage, and the optical measuring method remains reliable across that temperature range.
