Product Description:

The MHD112B-048-NP0-AN is a servo motor from the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. As a feedback-controlled rotary actuator, it is intended for positioning, contouring, and speed-regulated tasks on packaging lines, gantry axes, and similar industrial automation equipment. The motor converts electrical energy from a servo amplifier into mechanical rotation while providing real-time position data to the control loop. This arrangement supports accurate starts, stops, and speed changes during repeated machine cycles.

Its continuous stall torque is 28.0 Nm, giving machinery a stable torque reserve for holding or slow-speed duty cycles. A centering diameter of 130 mm aligns the stator housing to machine flanges for concentric mounting, and the B-length housing fits the 112 frame size without adding unnecessary bulk. The stator jacket uses liquid cooling channels, so thermal dissipation is handled by coolant instead of airflow and the motor can operate in enclosed installations where ambient air circulation is limited. Feedback is supplied by a digital servo feedback (HSF) encoder, which transmits high-resolution rotor position for tight velocity control and accurate commutation. Because the motor is built without a holding brake, the axis must rely on drive torque or an external clamp to maintain position when power is removed.

A square flange measuring 192 mm provides the standardized mounting face for direct attachment to machine structures or gearbox adapters. The output shaft has a keyed shaft profile to transfer torque to couplings or pulleys without slip under normal operating loads. Winding code 048 matches the motor to compatible drive modules with the required electrical characteristics. For added protection, a shaft seal helps keep oil or coolant away from the bearing cavity. Power conductors exit on side A through an output connector, and relative position detection means the controller establishes an absolute reference after homing.
