Product Description:

The MHD093B-058-NP1-AN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for closed-loop factory automation, it interfaces with Rexroth drive controllers to deliver commanded speed and position to mechanical loads. Its keyed shaft and built-in encoder allow the unit to act as the primary rotary actuator in packaging lines, transfer systems, and general motion platforms.

At stall, the motor can provide a continuous torque of 17.5 Nm, which is the continuous load it can hold without overheating when current is limited to the rated value. Protection class IP65 seals the housing against dust and low-pressure water, so washdown or airborne particles do not compromise the bearings or windings. Internal liquid cooling removes heat through a coolant jacket rather than relying on ambient air, permitting higher power density than naturally cooled frames. Position feedback is generated by a digital servo feedback (HSF) encoder, giving high-speed resolution for dynamic control loops. Torque is transferred to machinery through a keyed shaft, and mounting is simplified by a 140/150 mm flange and a 130 mm centering pilot that align the frame with gearboxes or direct-drive hubs. Insulation class F materials and winding code 058 set the thermal limits and electrical resistance.

The motor can be stored at -20 to +80 °C and operated continuously between 0 and 40 °C; these limits protect magnet strength and lubricant viscosity. A holding brake delivers 22.0 Nm of static torque to keep vertical loads secure when the drive is disabled, and accuracy in closed-loop mode reaches ± 0.5 angular minutes through the optical measurement method and relative position detection. A shaft seal is fitted to prevent coolant ingress, power is routed through an output connector on side A, and installations are permitted up to 1000 m above mean sea level.
