Product Description:

The MHD112B-024-PP0-LN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a rotary actuator, it converts drive controller commands into controlled shaft rotation, allowing positioning, velocity, and torque regulation in automated assembly stations, material handling axes, and machining centers. Its electromechanical design pairs with Indramat digital drives to create closed-loop systems that maintain repeatable motion profiles while minimizing wear. Because the motor uses digital feedback and a liquid-cooled housing, it suits duty cycles that demand high continuous power in confined cabinets.

The mechanical interface begins with a centering diameter of 130 mm, providing concentric alignment between the motor face and adjacent machine frames. A 192 mm square flange provides the bolt pattern for rigid mounting. At standstill, the motor can deliver a continuous torque of 28.0 Nm, ensuring steady load support without thermal overload when coupled to precision gear stages. Heat generated by copper losses is removed through liquid cooling channels that circulate coolant around the stator jacket, permitting higher current density than air-cooled designs. Power is transmitted through a keyed shaft, so the driven element locks to the shaft mechanically and resists slip under cyclic loads.

Position feedback is provided by a digital encoder that offers absolute (>4096 revolutions) resolution, enabling the drive to recover exact rotor angle after power cycling without homing routines. Electrical energy enters through a power connector located to the left of the housing, a layout that helps with cable routing inside multi-axis modules. The stator’s winding code 024 indicates the voltage constant and rated speed curve used by the drive during commutation tuning. A shaft seal is present to limit the ingress of cutting fluids, and the liquid-cooled body is identified by motor length B and size 112 for standardized envelope planning.
