Product Description:
The MHD115A-035-PG1-BA is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for precision axis control in industrial automation, where regulated torque and accurate positional feedback are needed for packaging lines, gantry drives, and material-handling stations. A digital servo feedback encoder with absolute multi-turn capability is integrated into the housing, so the controller receives position data immediately after startup without a separate transducer. A plain shaft supports direct mechanical coupling, and an internal holding brake keeps the axis secure at standstill during a power interruption.
The motor can deliver a continuous standstill torque of 32.0 Nm, which supports sustained load holding without overheating under rated conditions. It uses a flange dimension of 192 mm and a centering diameter of 180 mm for an accurate mounting fit and stable shaft alignment. The enclosure carries an ingress rating of IP65, so dust is excluded and water jets do not interfere with operation. When dynamic stops are required, the built-in brake provides 70.0 Nm of torque to resist reverse motion. Heat is removed through natural convection, so the housing depends on unobstructed airflow around the motor surface. Class F insulation protects the stator windings, and winding code 035 matches the electrical characteristics expected by a compatible drive.
The assembly operates at ambient temperatures from 0 to 40 °C and can be stored between -20 to +80 °C without damage to the insulation system. Overall system precision is supported by a positioning accuracy of ± 0.5 angular minutes, which helps reduce accumulated error during repeated indexing and coordinated multi-axis motion. Installation is limited to 1000 m above mean sea level, and a radial shaft seal helps keep lubricant away from the feedback section. Power and feedback connectors exit on side B, which can simplify cable routing when the motor is mounted close to guards, brackets, or other machine structures.
