Product Description:

The MHD112B-048-NP1-BN servo motor is manufactured by Bosch Rexroth Indramat and is part of the MHD Synchronous Motors series. It serves as the electromechanical actuator in industrial automation cells that require accurate speed and position regulation, such as tool changers, pick-and-place stations, and gantry axes. Coupled with Rexroth drives, it turns commanded currents into controlled shaft rotation while delivering feedback for closed-loop motion. The frame follows series mounting geometry, so it fits machine layouts that use this mounting pattern.

The motor can exert a continuous standing torque of 28.0 Nm, giving the axis enough stall capacity for tensioning, clamping, or low-speed moves without overheating. A centering pilot of 130 mm positions the stator concentrically against the machine flange so radial runout stays within tolerance. Matching that pilot, the square flange measures 192 mm across, which sets the bolt pattern and couples the housing to gearboxes or bell housings with predictable rigidity. Thermal energy is removed through liquid cooling; coolant absorbs losses directly at the jacket, permitting higher continuous output than air-cooled frames of equal size. Rotor angle is reported with digital servo feedback in high-speed format, enabling the drive to calculate fine position increments for smooth vector control.

A holding brake rated at 22.0 Nm secures vertical loads when power is off and releases automatically during commanded moves. Power conductors terminate on an output connector on side B, simplifying cable routing in cabinets laid out for right-hand service access. Motion is transmitted through a keyed shaft, which provides positive torque transfer to couplings or pulleys while preventing slip during reversals. The motor uses winding code 048, which corresponds to the electrical data expected by compatible drives.
