Product Description:
The MHD115B-058-NP0-AN servo motor is produced by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. Designed for closed-loop axis control in industrial automation, this unit converts drive current into precise mechanical rotation for positioning, conveying, and packaging equipment. A keyed shaft provides positive mechanical coupling, and the integrated feedback interface allows the drive controller to monitor rotor position in real time for accurate motion control. This arrangement supports repeatable axis movement in systems that require stable speed regulation and precise positioning.
The motor develops a continuous standstill torque of 50.0 Nm, which permits direct drive of medium-inertia loads without external gear reduction. Its housing has an IP65 rating, which prevents dust ingress and protects the motor against water jets. Heat generated by the winding is removed through liquid cooling, allowing full torque delivery even inside sealed machine enclosures. Position data are generated by a digital servo feedback (HSF) encoder with optical reading for accurate commutation. Mechanical alignment to the driven assembly is handled by the 180 mm centering diameter and a 192 mm square flange. The motor uses class F insulation, has winding code 058, and has a length variant of B. Power is routed through an output connector on side A, a shaft seal is fitted, no holding brake is installed, and relative position detection is supported.
The servo offers a positional tolerance of ± 0.5 angular minutes, supporting precise interpolation in multi-axis gantries and other coordinated motion systems. It can be mounted at elevations up to 1000 m above mean sea level without requiring operating changes. During operation, the motor maintains rated performance within an ambient temperature range of 0 to 40 °C. For storage and transport, it can withstand temperatures from -20 to +80 °C without damage to its basic mechanical and electrical components.
