Product Description:

The MHD112C-058-NG0-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It converts electrical energy into precise rotary motion for positioning or speed-regulated axes in industrial automation cells. In service, the motor supports closed-loop motion tasks where repeatable response and stable operation are required across changing load conditions. This makes it suitable for automated equipment that depends on controlled acceleration and consistent stopping accuracy.

Its continuous stall torque is rated at 38.0 Nm, allowing the shaft to maintain load during prolonged standstill without thermal overload. A centering diameter of 130 mm locates the motor accurately on the machine interface, while the 192 mm square mounting flange provides a rigid bolt pattern for installation. Heat generated by the windings is removed by liquid cooling, with coolant circulating through housing channels to limit stator temperature during continuous duty. Rotor position is returned to the drive by digital servo feedback (HSF), providing high-resolution incremental data for fast current and velocity control. This combination supports accurate motion on axes that need steady torque output and low thermal drift.

Position evaluation is relative, so the axis requires an external homing routine at startup. The motor uses a plain shaft with a shaft seal to reduce coupling backlash and help limit oil or coolant ingress, and it does not include an integrated holding brake. Power leads exit on side B, and terminations use an output connector for straightforward cable routing at the non-drive end. Winding code 058 identifies the electrical characteristics matched to compatible MHD drives, while motor size 112 indicates the frame size used in this family. Length code C gives the motor a housing length that supports the torque class without making the unit unnecessarily long. The layout also supports compact installation in enclosed machine assemblies.
