Product Description:
The MHD112B-024-NG2-AN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. This motor is intended to deliver closed-loop rotational power to axes in automated machinery, where precise speed and torque regulation are required for coordinated motion tasks such as packaging, material handling, and machining. As a servo unit, it converts controlled electrical input from a drive into mechanical rotation while returning position data to the controller for accurate trajectory tracking.
The motor’s mechanical envelope includes a centering diameter of 130 mm and a 192 mm square mounting flange. This interface matches the ISO size used for the 112 frame class and supports accurate alignment during installation. Continuous torque at standstill is rated at 28.0 Nm, so the shaft can hold that load indefinitely without exceeding the stator’s thermal limit. Heat generated under this load is removed through liquid cooling channels in the stator jacket, allowing higher duty cycles than comparable air-cooled units. Position feedback is supplied by a Digital servo feedback (HSF) encoder, which provides high-resolution incremental data to the drive for stable speed and position control. The motor length code B, winding code 024, and plain housing complete the configuration.
Additional features support load holding and cable routing in machine installations. A spring-applied brake delivers 32.0 Nm of static torque, keeping vertical axes in position when power is removed. The drive end uses a plain shaft with a fitted shaft seal, which helps prevent light oil or coolant splash from reaching the front bearing. Power cables attach through an output connector mounted on side A, so the cable exits parallel to the motor body for compact routing in tight spaces. Relative position detection is maintained by the encoder, and the overall motor size 112 helps limit mass while preserving torque density.
