Product Description:

The MHD112B-048-NP0-BN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. In automated production cells, this motor converts drive commands from a digital amplifier into precise rotational motion, supplying regulated torque and speed for gantry, transfer, and processing axes. Its synchronous design supports accurate response during repeated starts, stops, and speed changes in closed-loop motion systems.

This model can sustain 28.0 Nm of continuous torque at standstill, allowing fixtures or vertical loads to be held without thermal overload. A built-in jacket provides liquid cooling, so heat is removed through circulating coolant rather than ambient air, keeping winding temperatures stable during high-duty cycles. The centering pilot is 130 mm in diameter, aligning the stator housing concentrically with the driven machine frame, while a square mounting interface of 192 mm flange size distributes mechanical forces evenly. Position feedback is handled by a high-speed digital servo feedback (HSF) encoder that delivers incremental signals for tight velocity regulation and absolute multiturn data for homing routines. The motor is supplied without a holding brake, so external means must secure the load during power loss, and a shaft seal blocks lubricant migration into the bearing cavity.

The winding code 048 sets the electrical values used by compatible Indramat drive controllers. Frame designation 112 identifies the motor size, while the B length keeps the housing shorter for installations with limited space. Torque is delivered through a keyed shaft, enabling straightforward coupling to pulleys or gearboxes without relying on friction fits. For streamlined cable routing, the power connector is oriented toward side B, separating it from feedback wiring and helping reduce electromagnetic interference. Relative position detection is also available when the application uses incremental data for motion profiling instead of full absolute position information.
