Product Description:

The MHD112B-024-NP0-BN is a servo motor manufactured by Bosch Rexroth Indramat and part of the MHD Synchronous Motors series. In an automation line, it converts controlled drive current into proportional shaft torque for indexing, feed, or traverse axes under CNC or PLC supervision. Its liquid-cooled frame supports continuous duty while maintaining stable speed regulation on medium- to high-power stations. This design suits machine axes that must keep motion consistent during changing process loads.

Its centering pilot measures 130 mm, providing a reference diameter that helps keep the stator concentric with the machine frame. The motor provides a continuous standstill torque of 28.0 Nm, so reducers or direct-drive loads can be matched to the available holding force without overheating during stationary operation. Position data comes from digital servo feedback (HSF), which sends high-speed incremental signals to the drive for rapid velocity and position control. Heat is removed through liquid cooling passages in the housing, allowing higher RMS load than comparable air-cooled designs. The square mounting face uses a flange dimension of 192 mm, matching common ISO machine interfaces. The feedback and cooling arrangement supports accurate closed-loop response during continuous production cycles.

The power leads exit toward side B through an output connector, which can simplify cable routing when the motor is mounted opposite the load. A keyed shaft transfers torque securely, and the shaft seal helps keep coolant or lubricant away from internal motor parts. Because the unit is supplied without a holding brake, external locking must be used when the axis must remain fixed after power is removed. Rotor feedback is based on relative position detection, so the control system references movement from the last index mark rather than from an absolute value at startup. Electrical characteristics correspond to winding code 024, matching the electrical constants expected by compatible drive systems.
