Product Description:

The MHD112A-035-NG0-AN is a servo motor manufactured by Bosch Rexroth Indramat in the MHD Synchronous Motors series. It uses a 112-frame stator with winding code 035, giving the motor a mid-power profile that fits compact axis modules. Designed for industrial automation, the unit provides closed-loop torque and position control for indexing tables, gantry drives, and packaging machinery that require accurate and repeatable motion. Its synchronous design helps the connected drive maintain stable response during frequent starts, stops, and direction changes.

The motor delivers a continuous standstill torque of 15.0 Nm, allowing holding or low-speed positioning without overheating. Heat is removed through a jacket for liquid cooling, so thermal load does not depend on cabinet airflow. A die-cast housing sealed to IP65 helps prevent dust and low-pressure water ingress during washdown cleaning. Rotor position is reported by a Digital servo feedback (HSF) encoder, enabling precise velocity and position control. Mechanical attachment uses a 192 mm square flange, and the power lead exits toward side A through an output connector that helps simplify cable routing. Output torque is transmitted through a plain shaft that mates with clamping couplings or shrink discs without key-related stress concentrations.

The unit can be stored from -20 to +80 °C and operated within an ambient range of 0 to 40 °C, accommodating unconditioned warehouse storage and typical factory floor climates. A system accuracy of ± 0.5 angular minutes supports fine interpolation in multi-axis assemblies, while relative position detection helps the axis retain reference after short power drops. F-class insulation withstands winding temperatures up to 155 °C, and installation is permitted up to 1000 m above mean sea level without derating. A 130 mm centering diameter promotes accurate alignment during mounting, and a shaft seal helps block lubricant migration.
