Product Description:

The MHD112C-024-NG3-BN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Serving as a rotary axis drive for automated machinery, the unit converts controlled electrical energy into regulated angular motion for positioning, feed, and spindle tasks. An integrated feedback system and a liquid-cooled housing allow the motor to supply sustained torque in compact installations common to modern industrial automation. This arrangement supports closed-loop motion on axes that must hold position accurately and respond quickly to drive commands.

At standstill, the motor can deliver 38.0 Nm of continuous torque, allowing stable low-speed holding without external gearing. Rotor position is captured by a digital servo feedback (HSF) encoder that uses an optical method for fast control loops. Mounting uses a 192 mm flange and a 130 mm centering diameter, matching other size 112 frames. Heat is removed through liquid cooling in the stator jacket, which supports use inside tight enclosures. An integral brake provides 70.0 Nm of static torque, and the plain shaft transmits motion without key-related stress concentrations. Winding code 024 indicates the electrical characteristics of the motor, and the power leads exit on side B through an output connector for orderly cable routing.

The housing has an IP65 protection grade, and a shaft seal helps limit ingress at the rotating interface. Class F insulation allows the winding temperature to rise safely during intermittent overloads, while the feedback system supports a positioning accuracy of ±0.5 angular minutes after referencing. Operation is permitted from 0 °C to 40 °C, and storage can range from -20 to +80 °C without damage to the insulation system. Installation is permitted up to 1000 m above mean sea level without derating. The size-C motor length works with the internal coolant passages to keep the front face available for couplings, gears, or other driven elements.
