Product Description:
The MHD115B-058-NG1-AA is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. In automation systems, it supplies controlled rotary power for indexing tables, gantry axes, and similar motion tasks that require repeatable positioning accuracy. A permanent-magnet rotor and high-resolution feedback work together to convert drive current into stable torque, helping the connected drive controller maintain smooth motion during acceleration, holding, and direction changes. This arrangement makes the motor suitable for applications that need accurate response without unnecessary mechanical complexity.
This model sustains a continuous standstill torque of 50.0 Nm, allowing it to hold load during extended dwell periods without overheating. For power-off or emergency conditions, an integrated holding brake provides up to 70.0 Nm of braking torque to keep the shaft from turning when electrical control is removed. The motor uses a 192 mm flange and a 180 mm centering diameter, which help align the housing accurately with the machine interface. These mounting dimensions correspond to frame size 115, giving the unit a mechanical envelope suited to medium-to-high torque axis assemblies where secure mounting and concentricity are important.
Position feedback is supplied through HSF digital servo feedback, so the controller receives fine incremental data for precise speed regulation and position control. Heat leaves the housing through natural convection, which removes the need for external fans and keeps the motor layout simple. The motor uses a plain shaft with an internal shaft seal, allowing direct coupling to gears or pulleys while helping protect the bearing area from contamination. Winding code 058 corresponds to the electrical characteristics expected by the matching drive, and the relative measuring system supports operation with a homing routine. Power leads exit on side A through an output connector, which helps keep cable routing organized around nearby machine components.
