Product Description:

Bosch Rexroth Indramat builds the MHD115B-058-NP1-LA for its MHD Synchronous Motors series. Classified as a servo motor, it is intended for precise velocity and position control in industrial automation, where its feedback interface pairs with Indramat drives to move indexing tables, gantry axes, or packaging mechanisms with repeatable accuracy. The unit combines a permanent-magnet rotor with a stator optimized for high torque density while still fitting a 192 mm flange footprint.

At standstill, the motor can sustain 50.0 Nm of continuous torque, providing a stable margin for holding static loads without overheating. A spring-applied holding brake provides a lock rated at 70.0 Nm, so vertical or suspended axes stay secure after power loss. Position data are generated by a digital servo feedback (HSF) encoder that uses optical scanning and a relative count, enabling fast homing at each startup. Protection against dust and water jets comes from the IP65 housing, and heat is removed solely by natural convection, which simplifies airflow requirements in sealed machine frames. A keyed shaft transmits torque directly, an internal shaft seal helps keep contaminants out, and power reaches the stator through a left-side power connector.

The motor uses F-class insulation, so its internal conductors tolerate high temperatures while ambient air may vary from 0 to 40 °C during operation and from -20 to +80 °C in storage. Installation is permitted up to 1000 m above mean sea level without derating. Precise seating is provided by a centering recess of 180 mm, matching the 115 frame size and the B-length housing used with winding code 058. When paired with the drive controller, the digital feedback chain achieves a closed-loop positioning accuracy of ± 0.5 angular minutes, supporting applications that require repeatable alignment after each cycle.
