Product Description:
The MHD112C-058-NG0-AN servo motor is produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It serves as the electromechanical actuator in industrial automation, converting controlled electrical energy into rotary motion for feed axes, spindle drives, and handling modules. The motor combines a permanent-magnet rotor with digital feedback so the paired drive controller can apply precise current and maintain commanded position and velocity during continuous or cyclic duty. This arrangement supports smooth response during acceleration, steady running, and repeated positioning moves.
The unit can deliver a continuous standstill torque of 38.0 Nm, which supports static load holding without overheating under rated conditions. Its square mounting interface uses a flange that measures 192 mm across, while the 130 mm centering pilot aligns the housing concentrically on machine frames to help limit radial runout. Heat generated in the stator is removed by liquid cooling, allowing higher RMS currents than comparable air-cooled models. Rotor position is reported through Digital servo feedback (HSF), supplying high-resolution incremental data that the control loop uses for fine torque modulation even at low speed. This feedback method also supports stable velocity control across changing load conditions.
Winding code 058 identifies the electrical resistance and inductance combination matched to the rated voltage range of standard Indramat drives. Mechanical output is carried by a plain shaft with an integral shaft seal that helps block coolant ingress. The position channel is configured for relative measurement, so an external homing routine establishes the reference position after each power-up. Power is introduced through an output connector on side A of the housing, which can simplify cable routing when space behind the motor is limited. The C-length stator and 112 frame size provide substantial torque density within a moderate installation depth, and the motor is supplied without a holding brake.
