Product Description:
The MHD115C-058-NP1-AA servo motor is manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Designed for industrial automation, it provides commanded rotary motion to machine axes that need consistent torque delivery and precise speed regulation. A permanent-magnet rotor, an internal encoder, and a closed-loop drive interface allow the motor to translate controller signals into coordinated movement for packaging, printing, and material-handling equipment. That arrangement lets the paired drive monitor rotor position continuously and correct load-related speed deviations during operation. This supports repeatable motion on indexing, feed, and transfer axes.
The motor sustains a continuous standstill torque of 70.0 Nm, so it can hold static loads without thermal overload when airflow is limited. A flange diameter of 192 mm mates directly to gearboxes or mounting plates, while the 180 mm centering pilot keeps the housing concentric with coupled mechanics. Heat is removed through natural convection, so no external blower or liquid circuit is required. Position data is generated by a digital servo feedback (HSF) encoder that operates in relative mode, giving high-speed incremental signals to the drive. The size-115 frame with C length gives the motor its overall envelope, and winding code 058 matches the electrical characteristics expected by the inverter. Because cooling is passive, the motor can be used where auxiliary airflow is not available around the axis.
An integrated holding brake locks the shaft during power loss and helps keep the axis at rest without external clamps. Motion is transmitted through a keyed shaft, and a shaft seal limits oil ingress from connected gearboxes. The power leads exit on side A through an output connector, which helps keep the cable plug clear of adjacent hardware. This arrangement supports compact motor installation where cable routing space is limited. The connector placement also helps route the power cable away from nearby couplings and machine surfaces.
