Product Description:

The MHD115C-035-NP0-AA belongs to the MHD Synchronous Motors series from Bosch Rexroth Indramat. This servo motor is intended for closed-loop axis control in industrial automation where precise torque delivery and position tracking are required. It is well suited to handling systems, machine tools, and packaging equipment that depend on repeatable motion. Its overall configuration supports stable servo response during repeated starts, stops, and positioning moves.

It delivers a continuous standstill torque of 70.0 Nm, giving machinery static load capacity without overheating. An enclosure rating of IP65 protects internal components from dust ingress and low-pressure water jets, allowing direct mounting outside a cabinet. Heat is removed by natural convection, so no external fan or liquid circuit is required when ambient conditions remain within 0 to 40 °C. Mechanical output is transferred through a keyed shaft, which simplifies coupling alignment and helps prevent slip under cyclic torque. The 180 mm centering diameter mates with a 192 mm flange, and the motor uses frame size 115 with length code C. The NP0 variant is supplied without a holding brake, so position retention must be provided by the drive or by external mechanics. Power and feedback conductors exit toward side A through a sealed output connector, and a shaft seal helps block lubricant migration.

Position quality is supervised by digital servo feedback (HSF) that uses an optical measurement method and delivers relative position data. Its system accuracy is held within ±0.5 angular minutes, which helps minimize following error in multi-axis platforms. For storage, the unit tolerates temperatures from -20 to +80 °C, and operation is permitted up to 1000 m above sea level without derating. Winding code 035 identifies the electrical values used for drive matching, and the relative feedback system requires a homing routine after power-up. The optical encoder channel also helps reduce the effect of magnetic interference on feedback signals.
